Multi camera production

1) How does multi-camera production differ from single camera, what constraints are faced by multi-camera productions and what benefits does multi-camera production offer?


In typical multi-camera productions, dramatic actors have to memorize lines for a complete production. They may even have to go through the whole production without stopping. Lighting, audio, make-up, etc., have to work for long shots and close-ups, and for a variety of different camera angles. Soap operas (Emmeradale, Days of our Lives, Eastenders) talk shows (Graham Norton, Conan, Late Show with David Letterman) some sitcoms (Friends, How I Met Your Mother, The Big Bang Theory) more frequently use the multi-camera setup. Multiple camera shooting is the only way that a scene involving multiple actors performing in front of a live studio audience may be recorded from multiple perspectives. In the picture is one of the three main sets used in the multi-camera sitcom Friends. The set is Joey and Chandler’s bedroom, in Episode 222, The One With The Cake (Season 10 Episode 4).In the photo above there are three cameras being manned, with possibly another which isn’t in the photo. The lighting and the set is set up easily in a soundstage, but a lot of lights are being used, 18 are visible in this picture, no doubt there are more. This is so that an entire scene can be filmed, theoretically, in one take. The lighting arrangments and the number of cameras means that setting up would normally be a very time consuming process, but with a big-budget sitcom like Friends, there are a lot of men on the set to make this job very quick. 

Multi-camera compared to single-camera production.
A disadvantage of single-camera production is that filming each shot individually and setting up the lighting for each shot can take much longer than filming one entire scene in multi-camera. In some cases, it can sometimes be more expensive to produce than multi-camera because it takes much longer to produce a single scene, and the post production editing time can be very time consuming. If a multi-camera production is edited live, then there is little to no post production editing needed. Obviously in single camera, one singular camera is recording at one time. There may be more than one camera being used by the film crew, but they will not be set up and connected together like in multi-camera. In single camera is it reasonably more difficult to create a sense of realism with the cuts in post-production editing, because in multi-camera everything is happening live but in single camera, you have to work to get it to look live (matching up frames and creating fluid transmissions). 
Multi camera production is a method of shooting television programs, live events (for example football games and rock concerts) and films where several cameras are employed on the set to record or broadcast a scene simultaneously. Usually, there are two outer cameras for close shots of the most active characters and a central camera for the master shot, capturing the overall action and establishing the geography of the set.
Disadvantages include a less optimized lighting which needs to provide a compromise for all camera angles and less flexibility in putting the necessary equipment on scene, such as microphone booms and lighting rigs. These can be efficiently hidden from just one camera but can be more complicated to set up and their placement may be inferior in a multiple-camera setup. While shooting, the director and assistant director create a line cut by instructing the vision mixer to switch between the feed from the individual cameras. In the case of sitcoms with studio audience, this line cut is typically displayed to them on studio monitors. The line cut might be refined later in editing, as often the output from all cameras is recorded, both separately and as a combined reference display called the q­ split. 

The video below is a video of Oasis playing in Manchester in 2005. At the start of the video at 3:20, a few seconds into the first song, the show is stopped because of a problem with the barrier at the front of the crowd, and they needed the crowd to step back from the front in order to fix the barrier. Multi-camera is used well in this instance as the cameras are filming parts of the situation which are relevant to what's happening. For example, when the song is stopped and Noel is letting the crowd know what's happening, Noel says "take two or three steps back from the back, get it sorted..." there is a shot from the crowd's point of view followed by a shot of the team telling people to move back, and a wide shot of the crowd of the broken barrier. When Noel continues to joke about the crew are going to lose their jobs as a result, there is a shot of him pointing towards the crew and then a shot of the crew's reactions. 
This is a good example of live multi-camera because it shows the possibility and adaptability of multi-camera production. Single camera wouldn't work in this instance because using one camera would mean that the camera would have to be repositioned for each shot.



In a live event such as a sports event or a music concert, multi-camera set-up is the only method that can be used. It allows the entire event to be shown, and nothing is missed. For example in a football game, you can go back to specific things that have happened for different angles, because the multiple camera set-up has allowed there to be several cameras trained on the same thing, live. This wouldn't work in single camera as you would miss the action, and the live event is only happening once. Multi-camera is used very effectively in live music concerts, which differ to sports events as there are no replays and all the cameras are showing different aspects of the show (for example wide shot, crowd, singer, drummer etc.). This is so that it is interesting to the viewer and it makes it more entertaining. in most instances the sports and live music shows are being broadcasted on live television and so the editing is done there and then, as it happens. This eliminates the need to edit in post-production, which saves a lot of time. Also it is not possible when it's being broadcast live on TV. It is also a virtual necessity for regular, high-output shows like daily soap operas, which often film several episodes a day and need quick and easy and cheap production method. Once the camera and the lighting are set up, the entire scene can be shot in one take if needed which saves a lot of time compared to single camera where you would be needing to set up the lighting in each and every shot, a reposition cameras, and make sure there was continuity. Disadvantages include a less optimized lighting which needs to provide a compromise for all the camera angles used and less flexibility in putting the necessary equipment on scene, such as microphone booms and lighting rigs. These can be efficiently hidden from just one camera but can be more complicated to set up and their placement may be inferior in a multiple-camera setup. 

4) Analyse a 5 minute section from one studio based and one live-event based multi-camera production and discuss the techniques employed in each. How many cameras have been used and how and why have they been positioned as they are? Discuss use of camera (movement, framing and angles), coverage of action, lighting, editing, sound (diegetic and non-diegetic) and any use of effects or graphics. Try to use the correct terminology throughout your discussion. 

The video I have chosen to analyse is a section of the video that I have used above, between 1:02:17 and 1:07:30.
At the start when before the song starts, there is a wide shot of the stage, waiting for the next song to start so that they director can cut to different relevant cameras. The wide shots are used as a safety net so that if something goes wrong with some of the cameras or the direction of the vision mixer, then the wide is there to fall back on. When the drummer starts the beat at the start of the song, the video cuts to two closeups or the drummer, which have already been in position as the camera direction will know the song and will know beforehand which shots to position. There is then a wide from the crowd's point of view of the stage (again another safety shot) which moves nice and smooth into a tracking dolly shot of the piano being played as that is a dominant instrument in the intro of the song. The shots are relevant to the song that's being played. There is then a quick shot of the drummer as the intro drum fill is played, which is a well choreographed shot. This version of the video may as well be edited after in post-production, in order to get the shot timings right if the team messed up, but most of it will be edited straight off as it happens. Another well timed shot is when there is a cross-dissolve transition into a close up of the singer as he starts singing. Then a slow fade to a wide shot of the audience, and another shot from the audience's point of view which are like filling shots while the first verse is played, which could be because there is less to work with because than a specific instrument as like in a guitar solo for example. There is a few shots like this on different band members and then a shot of Noel as he does the guitar fill which leads into the chorus. There is then an extreme wide shot of the crowd as you can hear them singing along to the song. During lots of shots of the crowd, there is a shot of Noel singing away from the microphone, which is the reason behind there not being any vocals heard from the band, which helps the viewer understand what's going on. There is then a shot if the lead guitarist as another guitar fill is played. Mostly all the effects that are used during the video are cross-dissolves which could have been edited into the live show or added in post-production before it was broadcast. The effect is used effectively because the song is quite a slow-moving song, and the dissolve makes the cuts smoother. In a more faced-paced song, the cuts will just be straight cuts and the shots will be a lot quicker and less smooth. The sound is all from the output of the sound mixer, which will be mixed live by sound engineers, but there will be a separate sound engineer for the output for the live TV show because they sounds needed for the crowd and the TV differ greatly (i.e. the sound of the crowd is not played through the stage speakers). There aren't a lot of effects needed to be added onto this multi-camera production as it will all be done live. There are many cameras used, there are at least four on stage, with four wide shots, and at least two at the sound desk for close ups of the singers. And more at the foot of the stage. It is difficult to tell as in a production like this, the cameras are constantly moving all over the place. 




The second video that I am analyzing is a section of an episode of Mock The Week. The show is filmed in studio in multi-camera. The first part of the video is when the guests and the presenter are discussing a photo. The VT of the picture is used, and when they are playing the game and saying what they think the headline of the photo is, the VT is quickly shown to show a reference to show what they are talking about. There is one camera on the presenter, two cameras on each of the three guests on each side. And a close up camera on each row of three, making at least five cameras in total. The wide shots are used as a back-up as the close-up cameras are moving to each guest who are talking. There is a medium shot of the presenter and this camera will always stay just on him because he is the most frequent speaker and the center of the show and will always need to be gone back to in the show. The show doesn't get broadcast live, so some post-production is available if anything goes wrong.

Media Production Unit 23 - Multi-camera - Production Blog

Production Diary for Multi-Camera Production
(a)

Tuesday 25th Feb -

We found out who was in our group, and then got together and discussed ideas. It went well.

Wednesday 26th Feb -

Another group discussion, ran through some examples of multi-camera production in the studio, which were fun and got us really hyped for the project we're doing! We had an idea but we're still in disagreement over it.

Thursday 27th Feb

Working on pitch which is due in on Friday.

Friday 28th Feb -

Group discussion doing work for the pitch. We now have a clear idea which we have all decided on which is the news idea.

Tuesday 4th March -

Group discussions, and mind map completed.

Wednesday 5th March - 

Planned out the set design.

Thursday 6th March -

Forward planning sheets, studio work, floor plan completed (lights, cameras, seating) Questions for vox pops.

Friday 7th March -

Co tinted with the script, set layout, logo designs and music progress. We sorted out our folders and added to the questions that will be used in the show.

Tuesday 11th March -

Continued with script went to the set and set up lights, made sure it's all sorted. We also did our first run through of the show. Also other things like the music and planning shooting dates (tomorrow) for vts.

Wednesday 12th March -

Ash and Izzy went to film some of the vox pops which we lost the SD card several days later.

Thursday 13th March - Enterprise week 

Wednesday 19th March - 

Vox pops filmed, had another practice/run through of the show, we were testing the show for the two presenter format, which we had doubts about at first, but it was our original idea and when we ran through it and it worked really well. The script had to me adjusted slightly because the questions that we were asking the students in studio were the same as the questions that we were asking students in the vox pops . we lost the sd card so we had to film some more vox pops and presenter links with izzy and Alice.

Thursday 20 March - 

Filmed a lot of vox pops today for the vt about enterprise week. Finished the script and progressed on set design (completely changed the whole thing). 

Tuesday 26th March -

We filmed the production on Tuesday. We recorded the whole thing on the first take. The production went really well, the only thing that let it down was the guests. Our choice in guests could've been better. 

(b)
- What was your role and what were your responsibilities?
My role was the sound desk, setting up the lights, hot heads, camera positioning, set layout (chairs, table, set boxes etc) stage plan, partly helped with the script, part editing of the VTs (critical last minute edit before shoot), setting up microphones, sound checks, on camera with Izzy doing vox pops (which we lost), parts of the set design, getting plants for the set and setting up all the cameras on the day (white balance, exposure, framing etc). 
- How well did you carry out the tasks you were allocated?
I feel like I carried out my tasks well, but at times I lacked the motivation to help as a team, which was due to some unhealthy relationships in the group and some personality clashes. I think for me personally I could've been a better leader, as sometimes the group lacked guidance. All the practical tasks that I was allocated turned out very well done in the end. The sound at the time of the shooting was good. 

- How well did you work as part of the team?
As I mentioned above, we could've worked better as a team if it wasn't for a strong personality clash in the group. I think that in a professional situation if there was such a clash then they would just have to put it behind them and get on with the task that they have been allocated and not let it affect their profession work. 

- How could your contribution have been improved?
I feel as though I could've been more motivated and worked harder at times, and I personally could've worked to bring peace to the group as I think this was a critical matter in the turnout and the quality of the production. 


- Looking at the P3, M3, and D3 criteria, what criteria do you think you have achieved? Try to justify this grade honestly with reference to the way you performed in your operational role. 
Looking a the criteria, I think that I have achieved a merit. I think that individually I needed some assistance at times but generally I worked to a good technical standard, because of my roles such as sound, camera setup and set planning. These things were critical to our group and helped maintain the good technical standard.

Single Camera Production Blog

10/01/2014

Production Pitch 
On Tuesday we got given the Single Camera Production brief. On Wednesday we worked one our ideas for the project. On Thursday we decided on a final idea, and completed the pitch. We pitched our short film to the group today (Friday).

---------------------------------------------------------------------------------------------

Pitch
Genre – Drama
Plot – Man standing on a rooftop, looking back on his life. He has a series of flashbacks to when he was in a happy relationship and about to become a father. His girlfriend gets kicked out of her parent’s home after they find out that she’s pregnant. She goes to live with the man but arguments start because of the stress of having a baby. The girl gets post mortem depression and kills herself/ODs. He ponders about jumping of the rooftop for a while and then decides not to because of his responsibility and his love for his child.
Characters – Man, Girl, Girl’s Father and Mother, baby and a toddler.
Location – Rooftop, Girl’s house and Man’s house.
Casting – Performing Arts 
Production Schedule – Next week.
Other Films – Limitless

Roles
Jazmine - Producer
Kim – Director
Sam – Assistant Director/Sound
Ash – Camera/Editor
Anna – Camera
---------------------------------------------------------------------------------------------

Changes to pitch from feedback.
We received some feedback on our pitch which included a tightening on the roles within the group. I am now the editor and Anna is on camera. Research into post natal depression, and the main character has it and not the woman. She also does not kill her self, they just fall out. We changed the rooftop to a cliff top because that way the main character can have a progressive journey towards the cliff edge which wouldn't be possible. 
Production Schedule.
The Script is going to be done over the weekend and Monday and we will continue from that point. Jazmine will be contacting the Performing Arts at the college for our actors.

Unit 36: Interview Techniques for Creative Media Production

Interview Styles

Hard news style
Seen everyday on the daily news programmes. The questions are serious and to-the-point. These questions are used for informative purposes. An example of a Hard News Style interview is: https://www.youtube.com/watch?v=OXlTfbVFN3w The interviewer is asking formal questions in order to get an informed opinion. In this interview, very objective questions are used about the matter at hand. The questions are only about the matter at hand. Stephanie Booth has been specifically selected for the interview in advance because she is an expert on the internet and a very relevant person to the subject (it has not been selected loosely e.g. vox pops). The matter is serious, but the questions are level sided and there is not one biased side to the questions or the answers. The questions are purely for the purpose of finding out information on the subject. 

Investigative Style
Purely for finding out information on the particular subject. Can be used to interview a celebrity, a politician, or a person of particular importance, who has certain information which cannot be found elsewhere or is sought after. Investigative interviews are likely to contain a lot of closed questions which are aimed get a straight answer and usually to put pressure on the interviewee, so that the interviewer can find out the truth. 

Light-hearted
Light hearted interviews are not entirely serious. The interview subject could be a serious matter but the interview is conducted in a more casual way. The interviewee will be more comfortable because it is more generally orientated. 

Combative 
This style of interview is when the information or opinion that the interviewee holds is of some importance and so the interviewer will ask very biased questions in order to get the answer out of the interviewee. Quite often nowadays, politicians will get caught up in the news with stories and allegations involving their personal life, and will be engaged in combative interviews to try and get the truth out of them. The politician will want to participate in the interviews to try and gain back their public image. https://www.youtube.com/watch?v=Uwlsd8RAoqI. In this clip of Jeremy Paxman and Michael Howard, it is a very serious matter. As the interviewer, Paxman is trying to 'break' Howard by asking him specifically chosen questions to get a particular answer out of him. In this example, Paxman asks the question 'Did you threaten to overrule him?' (him being Derek Lewis) thirteen times, so that Howard will be put under pressure. He asks Howard the question so many times because he repeatedly avoids the simple yes/no question. In the end Paxman gives up because Howard does not back down. Combative interviews are filmed multi camera because the interview is taking place with two people face to face, and would be very difficult to film single camera with the interviewer asking the questions after. 

Promotional 
Promotional interviews are usually seen on chat shows nowadays. They are most often celebrities who want to promote their latest film or book etc. The interviews will be rather light-hearted and will mainly be about the thing that they are trying to promote. The interviewer will mainly ask open questions so that the interviewee can talk about their product fairly freely.

Interview Questions

Open
Open questions are very broad. They cannot typically be answered in the 'yes or no' format. An open question is very general, and the interviewee can answer the question using range of things about the interview subject. How wide range the answer is depends on the question. Open questions allow the interviewer to find out a lot of information about the subject. An example of an open question: "How do you feel about what happened at the game yesterday?". This question is open because it cannot be answered with 'yes or no'. 

Closed
The opposite to open questions. They are typically answered with the 'yes or no' format. These types of questions will we used in the investigative style of interview and will be used to get information out of the interviewee. Sometimes when an interviewee is asked a closed question in an investigative interview, the closed question will be ignored or 'answered' with an open answer, in order to avoid ether saying yes or no. If the interviewee is clever, he can make it so the interviewee is faced with saying yes or no, both of which will reveal wanted information.

Single
A single question is one main question about a subject. It is used closely with closed questions. 

Multiple
A multiple question can have several parts to it, and can either be asked at the same time or one after the other. More often than not, the interviewer will ask multiple questions at once. This is often used in light-hearted and promotional interviews as there is less pressure on the interviewee for each individual question.

Direct 
Direct questions are used in combative, hard news style and investigative interviews where the interviewer wants some specific information from the interviewee. Direct questions are very specific, and can either be open or closed. 

Leading
Leading questions are designed to that the question is biased to a particular side. The interviewee will be specifically looking for an answer which he is trying to get from the interviewee, and will use leading questions to try to get a biased answer. An example would be "You didn't enjoy the film?".

Evolution over the years
The first documentary film to feature an interview was Housing Problems (1935). The interview was fairly simple, just a woman talking to the camera about where she lived and what she did and the problems she faced. Through something fairly simple, spawned a whole new concept of documentary film making, and the move onto television. The evolution into modern interview nowadays Nowadays that form of interview has evolved into the promotional chat shows you see everyday, to the hard news style. These styles are a lot different to the interview featured in Housing Problems, but still have the main elements relating.

My documentary film, Island Collision, is an expository documentary dealing with a serious subject. The interviews that feature are a main part of the film, and are dealt in a serious manner. The interview style that I have chosen for the film is investigative, but keeping in mind the potentially sensitive issues that the film will discuss. The questions will be mainly open questions so that the interviewer can get the most amount of information that is available from the interviewee, and so that the interviewee can choose how much they want to talk about the sensitive issues without any pressure on them.

Understanding Video Technology

Ash Mosdell - Media Production Level 3 Year 1


Unit 21: Understanding Video Technology



Analogue and Digital Camera Technology



Analogue camera technology was introduced in the late 19th century, and was the original method of moving picture technology. The first moving picture cameras used a roll of film to capture frames in sequence. The film used exposure to light to capture the images. 

Digital camera technology was introduced in the late 70s, with several types of video production equipment with digital internals. Digital video was first introduced commercially in 1986 with the Sony D1 format. Digital video technology is now an extremely important aspect in every day modern life. 
Camera Functions
  • White Balance 
Changing the white balance changes the colour of a shot. When shooting indoors, the camera will need to compensate for the cooler or warmer colours. 
Auto White Balance (AWB) is a mode which is set to make the camera automatically choose the best setting for the current lighting situation, and generally does a pretty good job. But the camera doesn't know exactly how you want the shot to look, so a manual white balance setting is preferred. When shooting indoors, the type of light bulb that is being used can make the room either seem warmer or cooler. Tungsten bulbs make the colour of the room seem a lot warmer, whereas Fluorescent bulbs make the room seem a lot cooler. By selecting Tungsten and Fluorescent modes on a camera, you are able to compensate for the warmer and cooler colours, as the camera adjusts the colour levels. 
Custom White Balance allows you to tell the camera which area in the scene is supposed to be white. By holding a white piece of paper in front of the subject being filmed, the camera can get an accurate view of true white. Once the camera is set in the custom white balance, it will not change until you set another custom white balance or change it to any of the other white balance modes.
  • Focus
Changing the focus allows you to set what exactly is seen as sharp, and what is blurry in a shot. Auto Focus is the standard setting most cameras have. If Auto Focus is set, then the camera will automatically focus on the subject directly in front of the camera, or whatever the camera is pointing at. If the camera is set to Manual Focus, then the camera operator is able to change what is in focus manually by turning the focus ring on the lens. By having different things in the shot in and out of focus, the camera operator is able to put the attention on one particular subject. Manual focus can be used for a racking focus, which is when the focus moves from one subject to another, with one subject behind the other. 

Manual Focus Tutorial Video 
  • Exposure
Exposure is the amount of light that reaches the sensor in a camera, determined by the aperture. Aperture is a hole through which light travels.



Amateur and professional recording formats.
A very widely used example of an amateur recording format is the VHS, a magnetic tape based, analogue solid state. The VHS was used to record Television by using a Television recorder bo, which connected to the tuner. The quality of the VHS video varied from bad to not good, depending on the quality of the television signal being received by the TV tuner. A more modern way of home recording is using the digital DVD and Blu-ray disc format. The disc recording is made possible by using a Digital DVD or Blu-ray recorder. It connects to the TV Tuner or HDTV digital box. It is a lot higher visual and audio quality than VHS. A profession recording format is Betacam, which was developed by Sony in 1982, which came in both analogue and digital formats. 




The Digital Betacam format records a 3-1 compressed digital component video signal sampling in PAL at 720x576 resolution at a bitrate of 90 Mbit/s plus four channels of uncompressed 48kHz encoded digital audio.
Solid State recording format is SD (Solid State) card which uses flash memory technology. SD technologies have been implemented in more than 400 brands and more that 8,000 models. The capacity of SD cards can range from 1MB to 256GB.
The first video technology used cathode ray tube (CRT) television systems. The first video recorder was created in 1951, which used magnetic video tape on which the electrical  impulses  were  transferred.  



Solid State recording format





  •  Television Standards


PAL (Phase Alternating Line) is a colour encoding system used in analogue television broadcasting systems in most countries (primarily the UK, Austrailia, Brazil, and a majority of Asia and Africa. The resolution of broadcast is 576i. In the 1950s, Europeans countries were planning to introduce colour television, but wanted to overcome NTSC's weaknesses. The PAL and SECAM standards were created. The goal of PAL was to provide a colour television standard which had a picture frequency of 50 hertz, and overcoming the problems faced with NTSC. The signal of the subcarrier is 4.43361875 MHz. PAL has 576 visible lines compared with 480 lines with NTSC, which leaves PAL with 20% higher resolution (768 x 567). PAL uses a frame rate of 60i (half frames per second) or 30p. 

NTSC (National Television System Committee) is another analogue television system which is used primarily in the USA, Canada and a majority of South America. The typical resolution of NTSC is 640x480. The first colour standard of NTSC was created in 1953. After nearly 70 years of use, the majority of NTSC transmissions were turned off in 2009 and 2011. The signal of the sub carrier is 3.579545 MHz. 

SECAM (Sequential Colour with Memory) is also an analogue television system which was first used in France. It is the first colour television standard in Europe, with development starting in 1956. The first proposed system was a system named 'SECAM I' in 1961. The system uses the existing monochrome television receivers, but adds a second signal which carries the colour information. This is called chrominance. The signal of the sub carriers are 4.41 MHz and 4.25 MHz. SECAM typically displays half the vertical resolution of NTSC


  • Aspect Ratios
4:3 is the traditional television aspect ratio standard for video. It has been used since moving picture cameras (video cameras) were invented. 4:3 is the aspect ratio of 35mm films. Nowadays the aspect ratio of 4:3 is becoming less of a standard for television, and modern technology is moving on to the more favorable aspect of 16:9/16:10. 

16:9 is the standard format of HDTV, digital television, and PALplus. 16:9 is the only widescreen aspect ratio to be supported by the DVD standard. Even wider ratios can be achieved (in the DVD standard) by adding black bars the the image. 
1.85:1 is the UK and US widescreen standard for theatrical film, and was introduced by Universal Pictures in May, 1953. 





 2.39:1 is the aspect ratio of current anamorphic widescreen theatrical showings. It is a current cinema standard. Below is a film in the aspect ratio of 2.39:1, displayed on a screen of 16:9 aspect ratio (hence the black bars at the top and bottom). 




  • Video Signals 
DVI (Digital Visual Interface) is a video display interface developed by the DDWG (Digital Display Working Group). It is used to connect the video source to a display such as a monitor. It allows a maximum resolution of 1920 x 1080 at 60Hz displayed in 16:9 (1915 x 1436 at 4:3 aspect ratio).


HDMI (right) and DVI (left)

HDMI (High Definition Multimedia Interface) is a compact interface which carries uncompressed audio and video data. It carries uncompressed video and uncompressed/compressed audio from the source device to a compatible computer monitor, digital video projector or HD television. HDMI connections allow up to 8 channels of either uncompressed or compressed digital audio. HDMI 1.3 can allow for a maximum resolution of 2560x1600, which is possible because of the increased pixel clock rate to 340MHz. 


HDTV (High Definition Television) provides up to five times as many pixels as SDTV (Standard Definition Television). The maximum resolution which HDTV can transmit is 1080p (the standard HD resolution of 1920x1080p). (1080 pixels in height and 1920 pixels in width).
The 'p' stands for progressive scar, while 'i' stands for interlaced. For example, 1080p will be alot higher picture quality because it draws all the lines in a frame in sequence. 1080i draws only the odd lines in each frame, halving the quality. 




  • Broadcasting Systems
Terrestrial Television is a type of television broadcasting. It does not involve either satellite transmission or cables. Transmission is done by using radio waves, and antennas. In North America it is referred to as OTA (over-the-air television) and requires a tuner to view content. The first non-terrestrial way of transmitting television was in the 1960s and 70s by using satellites. Nowadays, analog terrestrial television is under threat from cable and satellite television, as well as the distribution of video and film content over the internet. 

Digital Television (DTV) is the transmission of audio and video by digitally processed and multiplexed signal. 

Internet Television is the distribution of television content, often in an 'on-demand' format, enabled by the use of the internet. It uses video streaming, and is used by many broadcasters.

  • Domestic, Professional and Broadcast differences?

  • Audio Equipment
Radio mics are battery powered microphones which are small and portable, lightweight and discrete. The mic itself is attached to a long wire which attaches to a battery pack and transmitter which is small and light enough to comfortably fit into a subject's pocket. Radio mics can be especially uselful when the individual is in a crowded area with alot of surrounding noise, it allowes the subject to be the main thing that is heard. The radio mics are connected directly to the cameras so that further syncing of audio and video later on is not required. 


Directional mics concentrate the audio which is being recorded in the area that they are being pointed at. Directional mics are long and thin, so it is easy to see where the mic is pointing when recording audio. The mics are usually used on the end of a boom pole, so that the sound operator can easily point the directional mic above a person, for example, without interrupting the shot. 


Voiceover mics eliminate any surrounding noise, which can be critical in a voiceover. Any distracting background noise can distract the viewer from what the narrative is saying, which can hinder the production. The voiceover mics are positioned infront and slightly above the person's head. The position is adjustable to get optimal sound. 


Audio Levels are vital to any sound recording. If the levels are set too loud, it can cause the audio to peak, which may cause distortion later on in the production stage. If the levels are set too quietly when recording, the sound quality will be negatively affected when it comes to try and correct it (louder). It can cause noisy and bad quality audio. 



  • Export Formats
AVI (Audio Video Interleaved) is a multimedia format created by Microsoft in 1992. AVI files contain both audio and video data. AVI is now somewhat outdated, and has some limitations, in that it cannot select the right aspect ratio automatically and that it cannot contain specific types of variable bit rate data reliably. AVI files can support multiple streaming audio and video, but it is rarely used.

DVD (Digital Versatile Disc) is an optical disc format, developed by Philips, Sony, Toshiba and Panasonic in 1995. DVDs have a much larger storage capacity than CDs while having the same physical dimensions. Data on DVD-ROM discs can only be read. DVD-R and DVD+R can be recorded onto once, then function as DVD-ROM. DVD-RW and DVD+RW discs can be recorded onto and erased multiple times. The most common type of DVD is the 4.7GB, which has a single-sided, single layer format. Double layer, and double sided DVDs have a higher capacity, ranging from 8.5GB - 17.08 GB. The weight of one DVD is 16g. 


H.264 (H.264/MPEG-4 AVC) is a video compression format, and is one of the most commonly used formats for recording, compression and distribution of video content. H.264 is best known as being one of the codec standards for Blu-ray discs. It is widely used by internet streaming sources, such as YouTube, Vimeo and the iTunes Store. It is possible to create lossless H.264 video. AVCHD uses H.264. XAVC is a recording format designed by Sony that uses level 5.2 of the H.264 format which is the highest level supported. XAVC can support 4K resolution (4096 x 2160) at up to 60 frames per second. Canon and Nikon DSLRs also use H.264.



MPEG is a working group of experts, that set the standards of audio and video compression and transmission. MPEG has standardized the following compression formats: MPEG-1 was the first MPEG compression standard for audio and video, commonly limited to about 1.5 Mbit/s. It was designed so that video and sound could be encoded into the bitrate of a CD. It can be used for low-quality video on DVD video. MPEG-2 is considered important, because is has been chosen as the compression scheme for over-the-air television signals on a variety of networks. It has also been chosen on some satellite networks and digital cable networks, SVCD and DVD video. MPEG-3 standardized scalable and multi-resolution compression, was intended for HDTV compression but was found redundant. MPEG-4 is more efficient than MPEG-2, and moves closer to computer graphics application. MPEG-4 supports DRM (Digital Rights Management). 




Digital Data Transfer

IEEE 1394 interface (AKA. Firewire) is a serial bus interface standard for high-speed communications and real-time data transfer. It was developed by Apple, in the late 1980s and early 90s. It is comparable to USB, though USB has more market share. Firewire has a higher data transfer rate that USB 2.0, but lower than USB 3.0. 

SD Card (Secure Digital) is a solid state recording format. An SD Card is a memory card which uses flash memory technology. SD technologies have been implemented in more than 400 brands and more that 8,000 models. The capacity of SD cards can range from 1MB to 256GB. They have particular advantages which include their small size, high capacity and high reliability thanks to their no moving parts (solid state) format.

Assignment 27: Task 2 - Codes and Conventions

What is factual programming? 
Factual programming is non-fiction genre of television programming, and more commonly known as documentary. A factual program can support, object, or simply observe a real life event, person or object, and can be environmental, historical, political and social. 


The three types of documentary film.
  • Observational documentaries attempt to simply observe a lived life with minimum interruption. There is no narration, they just observe. Examples include Industrial Britain.


  • Participatory documentaries involve believing that it is impossible for the act of film-making to not affect the events being filmed. These films incorporate the film-maker himself, and in doing this we also get to see just how much situations in the film are affected by his presence. Examples include Supersize Me by Morgan Spurlock.

  • Expository documentaries speak directly at the viewer. Their aim is to change the viewer's mind about a strongly biased point of view. Often you will find that a film-maker has used a deep male voice in the choice of voice over. The 'voice-of-God' commentary often sounds ‘objective' and powerful, and is more likely to persuade the viewer. Images are often not most important; they exist to advance the argument. Examples include, Bowling For Columbine, Fahrenheit 9/11 (both Michael Moore) 


Codes and Conventions used in documentary production.

Voice-over 
The voice over will have an authoritative tone, encouraging the audience to think highly of them, and in doing so they are more likely to side with, or listen to them. Examples include Michael Moore, (Bowling For Columbine), Nick Broomfield (Kurt & Courtney).
Sound
Diegetic sound is sound that has been shot along with video. Non-diegetic sound is sounds that have been added after (in the editing process), for example, different moods of music being used to reflect the image of the subject. For example, in Supersize Me, childish music is used to undermine McDonalds, but portraying them as a childish, trivial company. In Fahrenheit 9/11, Michael Moore added the song 'Shiny Happy People' to a section of the film containing archive footage of George H.W Bush and his son meeting with the Saudis, a critical point in the film. The lyrics 'Shiny happy people holding hands' is timed so that it plays over footage of them shaking hands and posing for photos with the Saudis.

To aid authenticity, and to add further information.
Use of 'experts'
Used to add a sense of authentication to the views expressed in the documentary. Can provide a worthy opinion.
Use of text/titles
Text on-screen can be used to display information quickly and effectively. Labels, dates etc tend to be believed unquestionably by the viewer.
Interviews 
Interviews are vital to a good factual program (unless it is observational). They can provide different point of view and diffrent opinions which can be arranged in a way that an argument progresses.

Balance is  Considering my own production.

My own production is an expository documentary titled 'Island Collision'. It aims to find out the cause of road traffic collisions involving young people on the Isle of Wight. Codes and conventions are used in my documentary to make the documentary more interesting.
Archive Images
In Island Collision there are several montages of archive images of multiple scenes of road traffic collisions. We have obtained these images from Tracy at Sandown Fire Station.We have obtained permission to use them from the fire station. Particular attention has been given to these images, as to not show anything graphic, but still make an impact on the viewer.
Voice-over
As our documentary is expository and not participatory, there will be no presenter, so a voice-over is being used to like scenes and sequences. The voice-over is a deep male voice, which will come across to the viewer as authoritative, and is more likely to make an impact on the viewer, as well as being informative with the facts and statistics that are being told directly to the viewer.
Music
As copyright is an important factor to take into account, we had difficulty in finding a soundtrack that suited our style of documentary, and one we had permission to use. We decided to commission a soundtrack from a friend. Because the soundtrack in question has no filed copyright and we have commissioned it ourselves, there is no legal issue with it. We have both lyrical and instrumental versions.
Other Archive Materials 
We have been provided with a 999 call from Sandown Fire Station from one of the collisions featured in our documentary. Appropriate permissions have been requested, but it is a difficult process as all people involved in the call have to give permission for it to be used, including the caller. We asked permission to gain a copy of the Head On DVD from the Fire Station, which contained useful images that we could take advantage of, but we were not allowed to hold a copy of it as it contains sensitive material which could be viewed by someone underage who is not expecting to see graphic images, and may cause harm to the viewer. Because of this we had to negotiate terms of permission. Tracy from the Fire Station agreed to giving us selected images from the DVD separately, after being screened by the Fire Station.
Different Camera Techniques
We have some creative and relevant cutaways that we have filmed. We hope that this will make the otherwise objective documentary more striking. In each of the interviews, we have re framed the shot at least once, every three questions or so. This will help to create a sense of professionalism, and keep the documentary more visually striking.
