Videos have advanced a lot since they first began, they have especially advanced since technology such as computers, smartphones, and advanced game consoles have become more interactive to users- enabling them to use more features than ever before. A large factor for this freedom in technology is now due to the Internet which was created in the early 1990's... It has since become a vital part of many people's everyday life.
The Internet has enabled websites such as YouTube to enable users (who have to register to the site; although it is now controlled with Google Accounts as it is part of the Google name) to upload their own videos that they have created to the website. This website is interactive because viewers can play/pause the video, turn volume up/down, and interact with links that can often be adverts or links to other videos that are related to the video being viewed. Many types of videos are published onto this website such as official music videos, or official trailers for an upcoming movie, or even a piece of footage from a family home that is funny.
The videos on YouTube can vary in qualities from:-
- 144p
- 240p
- 720p (High Definition)
- 1080p (High Definition)
Pixelation
Lossy compression reduces file size considerably but leads to pixelation and reduced quality.
Because of the advance in technology other types of media have become interactive, for example the following are interactive to users:-
- Fashion Websites (e.g. River Island, Topshop, ASOS)
- Digital Booklets (e.g. College Course Booklet)
- DVD (e.g. Menu to Play Film)
- Pornography (e.g. Interactive websites such as pornhub.com, hamster.com - OR films which can be published on DVD's)
- Video Games (e.g. Cut Scenes)
- Interactive Kiosks (e.g. London Underground offer payment options via an interactive kiosk with no cashier)
- Chat Websites (e.g. Chat Roulette)
- Interactive Books (e.g. iBooks on Apple Devices, or Amazon Kindle devices)
- Mobile Applications (e.g. Flappy Birds, Temple Run, Angry Birds)
- Billboards (e.g. LED screens advertising products)
- Online Adverts (e.g. "Shoot The Duck Five Times", "Click Here To Win"
- Interactive Games (e.g. Solitare, Snake)
Containers & Codecs
A
container (also known as a file type) is the term used for a file that will store data. This data is then read by the codecs to create the imagery that we see on the technology of today. Without a container the devices that we use in modern society would not be able to be played because the information would not be able to be properly processed.
A
codec is a type of language that computer systems use in order to create the information that it requires so that our personal devices such as iPhone's and Mac's process data to make it personalised to each of us. This language helps your computer systems to store and transmit files. There are many different types of codecs including:
(Video Codecs)
- Xvid
- DivX
- MPEG-2
- MPEG-4
- WMV
- DV
- VP8
(Audio Codecs)
- Vorbis
- FLAC
- AAC
- MP3
- Speex
Containers and codecs are used in:-
- Quicktime
- VLC
- Flash Player
- RealPlayer
- DivX
Many codecs are created for a specific system, for example if I tried to use WMV on an Apple iPhone then it would not work because WMV is programmed to work on Windows devices as opposed to Apple iOS devices.
Types of File Types:-
.AVI
.MOV
.MP4
.FLV
.MPG
.3GP
Quality vs. File Size
Quality is a term that is used to measure similar objects to each other- usually comparing each other against each other in terms of superiority.
In modern day society, where many people watch a lot of film and music quality is extremely important therefore people are very conscious when acquiring a product such as a film or song. For example, Blu-Ray is now seen as better quality than DVD because a Blu-Ray disk can hold more data on it (25GB worth of data or 50GB if it is double layered) therefore a film can be released in HD (High Definition) as opposed to a DVD which is average quality.
Resolution
A resolution in technology is a term commonly regarded with the quality of a video. When recording with a video camera, it will generally record at 24 frames per second. This basically means that in one second of footage there are 24 photographs. This convention can be opposed to make a certain style however this is how video makers will make a movie that looks realistic. Resolution is measured in multiple ways, this includes the following:-
- 'Lines per Inch' / 'Lines per MM' - this is considering how close lines are together and if they are visibly resolved.
- 'TV Lines / TVL' - this measurement considers how many lines there are in a picture because this rule says that lines often come in pairs and in these pairs one line is dark, while one line it light. For example, if there are 60 lines per millimetre then there would be 30 dark lines and 30 light lines and this measurement would be wrote down as 30LP/mm.
- 'Pixel Resolution' - this measurement determines how many pixels are in the image, this can be calculated with pixel columns x pixel rows ÷ one million. Each pixel helps to make up an image. Resolution depends on the number of pixels because the smaller the pixel, the higher the resolution will potentially be. If a pixel is too big then the films footage can become blurred & bad quality. This is commonly seen on video streaming websites such as YouTube where old footage will often be as low as 144p, which can create an extremely bad quality video... However it goes as high as 1080p which is high definition and is good quality. The negatives of having more pixels in a video is that the file size will become bigger because it will have to store more pixels away.
Examples of Poor Quality & High Quality Clips
This is a very low quality video screenshot from the Mean Girls trailer from YouTube. Youtube settings stated that this video was playing at the lowest of 144p which is low definition. Although it is extremely blurred and pixelated the positives of this low definition is that it is a smaller file size than a higher definition video.

This is a screenshot from the Lady GaGa music video 'Telephone', I played this on YouTube at 1080p which is the highest quality possible on YouTube. When compared to the Mean Girls trailer it is quite clear that this screenshot is a lot clearer and it has barely any pixelation at all. The negatives of this video resolution is that it is a lot larger to keep on a computer system than other videos.
When talking about definition modes people will often use the measurement of '
i', for example 1080i. This is not the same as 1080p because the
i is an abbreviation with regards to the frame resolution and the scan type, a 1080i video can play back at 60 frames a second however many broadcasts use 30 frames a second instead and it uses a process called interlacing. This contributes to the sense of motion and reduces perceived flicker. The
p stands for progressive scan and it is not interlaced like 1080i would be. 1080p is often referred as 'full HD / true HD' so that it isn't confused with 1080i. These definition modes are unlikely to be noticed unless you are using a larger television.
576i is the standard definition mode used when publishing videos of all genres, this definition originates from broadcasted television. It is also known as PAL (Phase Alternating Line), the mode is known for it's colour encoding system. It is regarded as a good system because it can hold 625/50 lines which is one of the largest systems when compared to others, this system is regarded as being 50hz. PAL will only work on systems that are programmed with PAL; these systems are only produced in set regions including the UK, most of Europe, most of Asia, Oceania and majority of Africa.
One of the other main modes that is widely used around the World is NTSC (National Television System Committee), this is known as 480i. This is the standard definition mode for some countries however it is not as large as PAL. The system is available is regions including North America, a small part of South America, South Korea, Japan and Taiwan as well as many small islands in the Pacific Ocean. This has a smaller 525/60 lines when compared with PAL but used 60hz which is larger than PAL.
There are other systems such as SECAM and PAL/SECAM too, although PAL/SECAM is extremely similar to PAL. These systems are the reason that if you buy a DVD from USA and you take it back to England you may not be able to play the DVD because of the different systems that are used in the regions. If you want to play a DVD that is from a NTSC region then you will have to use a NTSC video player.
The viewing distance is also an important aspect to consider when judging the quality of a video. For the best experience from a video you often have to sit in a set place to get the best picture quality. If you sit too close to a television you will often struggle to see a good quality picture because you may not be able to see the whole picture depending on the size of your screen and if you are close you are more likely to be able to see the pixels in the television, which will lower the quality of your experience because the pixels may look blurry to you. This does depend of the size of your television: the smaller the television, the closer you can sit to it. For example, many people try to sit at the back of a cinema when going to watch a film because the seats at the front are too close and it is hard to see the whole picture. However if you sit too far away from the screen you may also struggle to see the picture, this will make it hard to watch and the screen may be blurry because your vision isn't good enough to see something as small as the screen that far away.
Frame Size
The size of frames in a video often vary because different directors/producers have different preferences and it depends on what type of video they are aiming to create. It also depends on what technology is available to them and how much budget they have- for example, Avatar had more technology available to them than Donnie Darko because of the years that they were released in and because Avatar had a much higher budget than Donnie Darko.
Avatar was released in 2009 and had high quality HD technology available because of the budget that the film also had available. If you played this on a large screen it would look better quality than Donnie Darko (as you can see below).
Donnie Darko was not released in HD and therefore if you played this on a larger screen it would not look as good quality as Avatar would because Avatar was created for HD screens and larger screens.
The smallest frame that is used is 8mm; this is seen as 'amateur' and this is what a low budget film would use. The quality of this video would not be very good and would look very poor when compared to a frame rate of an IMAX frame size of 69.6mm x 48.5mm; this frame rate is extremely high when compared to the low frame size. The higher the frame size the better the quality of the video, if a frame size is larger the picture will look a sharper.
The most common format to be used is the 35mm. This uses a frame size of 36mm x 24mm and it will usually be shot in a horizontal position because when it is shot in a vertical position the frame size can vary which can lower quality, the only exceptions to this rule are Technirama and VistaVision.
Frame Rate
A frame rate is often referred as 'frame frequency' or 'frames per second' (FPS), although it may also be identified as being a progressive scan monitor in hertz (Hz); this is a unit of frequency in the international system of units (SI). It is commonly defined as being 'cycle per second' which describes the sine wave, it especially focuses on waves used in radio and audio applications. FPS is used by people who use both film and video cameras. Frame rates are also used in computer graphics and motion capture systems.
When filming, there will usually be 24 frames per second of footage. Each frame is basically a photo so when 24 photos are sequenced together they made one second of real time footage. If you use less than 24 frames then you will get a piece of footage that looks like it is being filmed in fast motion. If you use more than 24 frames when creating a second of footage you will then create a slow motion clip.
Showscan is a process that was created in relation to frame rates. It was created by Douglas Trumbull (responsible for special effects in films including
Star Trek: The Motion Picture, Blade Runner and
Brainstorm) so that 70mm film could be used, however it would be photographed and projected at 60 frames per second, which is 2.5 times the speed of the standard speed of traditional film. When he created the system it created opposing opinions in the film industry- with many doubting the system because of how unconventional it was. It was originally planned that it would first be used in the 1983 film
Brainstorm but the plans were never carried out. The technology has since been used in a lot of powered motion simulator seats, and despite the original criticisms of the system Trumbull and his associates received a
Scientific and Engineering Academy Award for the Showscan system. The Showscan Film Corporation filed for bankruptcy in 2002 which meant that the equipment and process was sold to a new company named Showscan Entertainment.
Data Rate
Data rate is the measurement of what rate information is transferred on a computer system. This is often measured in megabytes/second, although there are other measurements including kilobits/second. These help to determine how much space you will need to store a video on the heard drive of the device you are saving your video on.
Popular data formats include:
- MPEG-1
- MPEG-2
- MPEG-4
- Windows Media
- RealMedia
- DV
These formats often support a variety of different bit-rates and quality-based encoding systems. It is possible to work out the average of bit-rate by using the following equation:
[VIDEO BIT-RATE + AUDIO BIT-RATE] x # Seconds = Total File Size
[ # bits/sec + (# bits/sec) ] x # Seconds = (#bits)
Compression
A lot of digital data can be compressed to reduce file size, this makes it easier to store the file on a disk because it takes up less space. Compression can also reduce bandwidth which is required in order to stream a video.
There are two types of compression:
Lossy Compression- this type of compression will lose elements of the data when the file is being compressed, the problem with this is that quality will be less because if pixels are being lost then the picture may be more blurry and worse to look at.
Lossless Compression- this type of compression will not lose elements of data that is compressed, this does mean that the file will not lose quality however it may become a larger file size which some people may not like. This type of compression does aim at reducing the file size by searching for the data in the file that is not necessarily needed though.
Media Platforms
There are a lot of different places that an interactive video can be found... Here are just a few examples of where interactive videos can be found:
Video Sharing - video sharing has become a vital tool in the 21st century as the internet gets more and more important people's everyday lives. Video sharing started to become a massive part of the film industry when YouTube was created in 2005 by three former PayPal employees; Steve Chen, Chad Hurley & Jawed Karim. This type of website allows people to upload videos of anything within the boundaries of terms & conditions. Anyone from a mother filming their baby screaming to a film director creating the next Hollywood blockbuster trailer may upload videos that are completely different to each other. Companies such as VEVO and BBC upload videos onto YouTube for fans of their own websites and channels to see and with the hope that others will decide to look at their material. Video sharing websites often feature adverts before a video and this is how they generate income, companies may pay a lot of money to get their advert played on a video that has gone viral.
Video sharing websites are one of the most popular ways for people to view media nowadays, this is proven by the following facts:
- There are more than ONE BILLION unique users that visit YouTube each month.
- Over 6 BILLION hours of video are viewed on YouTube each month.
- 100 HOURS of video are uploaded to YouTube every minute.
- 80% of YouTube traffic comes from outside of the US.
- YouTube is available in 61 Languages and is localised across 61 Countries.
Video Games - A video game can often be an interactive video because a lot have cut scenes that you can be interactive, a good example of this is Max Payne 3- this game tries to play on the idea of a Hollywood action movie with many different effects that movies often use. Obviously the difference between this game and a movie is that you are more engaged with this game because you are controlling the character and you have to try and survive throughout all the missions. Video games can generate a lot of money because they are often sold for around £50 when they are first released- for example Grand Theft Auto V made $1billion after three days! Many video games in 2013 also had extremely high production costs that are similar to Hollywood blockbusters which was not previously seen a decade ago. This indicates that the video game industry is generating the same quality of product as the film industry is.

This is a screenshot from the game play in Max Payne 3, a very good example of how a video game can also become an interactive video because of the way that it is created so that it looks like a movie too.
As technology has advanced, video games have become a lot more realistic because of new technologies that have been discovered. A good example of advances in video game technology are when FIFA 2002 and FIFA 14 are compared together:
This is FIFA 2002, the kits are not very detailed and there were no names on the back of players shirts. The graphics were certainly not as good and players would often have the same body and face but with maybe a different hair colour.
This is FIFA 14, the graphics here have improved a lot, as well as the players looking completely different to each other because of the different technology being used. The technology being used now uses imagery of the players to create a virtual player that looks realistic. This game feels more like real life and it feels like you are watching a real life football game.
Here are some other good examples of advancement in graphics:
This is Grand Theft Auto 3, which was released in 2001. The game is more pixelized than Grand Theft Auto 5 and looks like an older video game instead of something that could be mistaken for realistic.
This is Grand Theft Auto 5, which was released in 2013. This game is one of the most realistic games available to us at the moment because its graphics are unbelievably good and it looks very realistic. This is because the technology that Rockstar Games used cost them over $200million to create this game, it certainly wasn't cheap to create however the game hit $1billion worth of sales in THREE DAYS so that makes the high production cost worthwhile I would say!
DVD Menu's - Although a film is rarely interactive, the menu that is often used on DVD's is interactive. The menu is usually controlled using a controller and there will usually be around 4-5 options that are available to the viewer. As technology and fashions have changed the DVD menu's have also changed; here are some examples of DVD Menu's from past & present:
This is the DVD menu for Slumdog Millionaire which was released in 2008, this menu plays on the storyline of the film. It is basic but it looks slick and is simple to interact with.
This is the DVD menu for the original Tron film created in 1982. As you can see, it is styled completely differently because of the different fashions of the time and because of the different technologies available to them at the time. I am sure if they were to recreate it now then it would be a lot higher definition.
There are also DVD games such as Deal or No Deal which involve the viewer interacting with the remote control to pick a box and then it will play a bit of film.
Mobile Devices
Mobile devices have become more interactive in the past 5 years because of the better touchscreen technologies that have been introduced. Phone's and tablets such as the iPhone, iPad and Samsung Galaxy Tab allow people to view films, listen to music... People pretty much can now do anything that they want to on these devices since they have become smarter. 10 years ago a mobile phone was used to ring and text people- it would not have been able to play BBC iPlayer.
Presentations
Presentations are often used to inform or pitch an idea to somebody, as technology has evolved people have been able to create a more interactive presentation and as a result people can often play videos on a screen behind them or use technology to help enhance their own performance. A good example of a high tech interactive presentation is when Apple often use press conferences to announce their new products, the presentation will usually be highly interactive and intriguing.
Apple will often use a presentation to announce new products such as new iPhones, iPads, Mac's as well as potential new products.
