Interactive Media Applications

Short films

• A short film is longer than a trailer or advert. It is a film cut down into a shorter version showing as much as possible in the time it lasts. Showing the full story quicker than it would in a full film instead of dragging it out.

• For example there are short films for new products to promote and sell them. To show what they do and the point of the product. These can be used as youtube adverts or adverts before a movie in the cinema etc.

• Platform – presentations, world wide web.

Promotional video

• A promotional video is a short clip promoting a product for example an artist will have a promo video for there new album or for there tour informing the audience of relevant information like dates and prices etc.

• Example – • Platform – email attatchments.

Film Trailers

• Film trailers are cut down and edited versions of films, showing the best bits, if it’s a comedy showing funny bits, an action showing the most shocking bits, a horror showing the scariest bits etc. It is to sell the film and make it appealing or more appealing to the audience.

• Example - They are usually shown in the screening of a different film to promote it, youtube adverts and on the cinema website for you to watch before deciding what to watch, or to help you decide.

• Platform –Presentations, DVD

User Generated Content (Web 2.0)• User generated content (UGC), also commonly known as 'citizen journalism', 'social

media' or 'participatory media', refers to a wide variety of media content that is produced by our audiences as opposed to content made by the BBC, independent production companies or individual contributors commissioned by BBC.

• Example - In recent years UGC has expanded due to developing technologies that are now readily available, including digital video and images, mobile text messages, blogging, message boards, emails and audio submissions.

• Platforms – Mobile devices

Viral Marketing

• You ask a person to send the original marketing message to a friend or friends; or you ask a person to give you their friends contact details.

• For example an advert or video of something that wasn’t planned and is up up on the web and on youtube and goes viral, everyone has seen it and is talking about it.

• Platform – World wide web (youtube)

Advertising

• Advertising is a short or sometimes maybe too long of a video on TV to purely to advertise and promote something.

• For example an advert for a new phone.• Platform – World wide web.

Virtual Reality Tours

• Virtually reality tours are pre recorded videos showing customers around a place.

• For example you can have a virtual tour around the BBC radio1 building, if your interested in looking or going on a real tour.

• Platform – world wide web, kiosks.

Games

• Video games are fictional games and characters that can be played online or on game consoles.

• Example - video games are made for consoles like PS3, Xbox 360 etc.

• Platform – CD, Mobile devices, world wide web.

E learning

• E - learning is a use of technology used to educate all done electrically.

• Example – Electric whiteboards in school.• Platform – Online – world wide web

Technology

Digital video capture• Digital video capture is the process of converting an analogue video signal

such as that produced by a video camera or DVD player to digital video.• Example - MoviePlus makes it easy to capture your own video and audio

footage to your PC from tape-based digital camcorders (e.g. Mini DV), analogue video sources (e.g. analogue camcorders, VHS, or TV all via a capture card) or USB web cams.

• Platform – World wide web, presentations, kiosks.

Compression

• (lossy) compression is a data encoding method that compresses data by discarding (losing) some of it. The procedure aims to minimize the amount of data that needs to be held, handled, and/or transmitted by a computer.

• (losless) data compression is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data.

• These are used in email attachments as files may be too big to attach in an email so need compressed.

Digital video file formats

• (mpg, mp4, mov, avi, wmv, flv, swf, 3GP, ASF)• Converting from one format to another is no more difficult

that doing a “save as” with a word document. You pick which format you want and the software does the rest. The trick of course is to have the right software for the job and know what format you want. Depending on the sophistication of the software you’re using, you might have options in terms of size, resolution, compression type, compression amount etc.

Example of what Avi is

• Video formats come in parts, layers and types. The “container” is part of the video file and it holds other parts. Any video you watch is made up of a container and numerous interior parts. For example, the video and audio are actually separate signals bundled together within the container.

Those interior parts can vary and the video still be considered a certain format. This leads to very confusing compatibility issues. Just because your format is something common like AVI does not mean it will work within a program that accepts AVI. Chances are it will not be too hard to make the necessary adjustments once you know what you need to adjust.

Streaming methods

• Downloading – is when you download something from online or a disc, it can be software, music, photos, a website link, audio, photos, any sort of file that you want on your laptop you have to download it to access it.

• Progressive downloading – is the transfer of digital media files from a server to a client, typically using the HTTP protocol when initiated from a computer.

• Streaming – is content sent in compressed form over the Internet and displayed by the viewer in real time. With streaming video or streaming media, a Web user does not have to wait to download a file to play it

Data transfer rate

• The speed with which data can be transmitted from one device to another. Data rates are often measured in megabits (million bits) or megabytes (million bytes) per second. These are usually abbreviated as Mbps and MBps.

File size• Resolution - Resolution is the term used to describe the number of dots, or pixels, used to

display an image.• Higher resolutions mean that more pixels are used to create the image, resulting in a crisper,

cleaner image.• Data rate - Data rate can refer to:Bit rateData signalling rateData rate unitsData transfer rate (disk drive)

• Frame rate - Frame rate is the frequency at which an imaging device produces unique consecutive images called frames.

• Key frame rate - The frequency with which key frames are placed into temporally compressed data sequences.

• Compressor - an electrical device which reduces the dynamic range of a sound signal.• Audio settings – allows you to play around and adjust the volume, pitch etc. of sound.

Aspect ratio (4.3, 16.9)

Aspect ratio is defined as the ratio of width to height of an image. A 4:3 aspect ratio means that for every 4 inches of width in an image, you will have 3 inches of height. In mathematical terms, that comes out to the screen being 33% wider than it is high. A 16:9 aspect ratio means that for every 16 inches of width in an image, you will have 9 inches of height. Unlike the 4:3 aspect ratio, a 16:9 aspect ratio is 78% wider than high.

Media players• Flash player• Quick time• Windows media player• RealMedia• Player• DivX• These are a list of media player you can use to open and play audio

files, music files and videos files. They are usually already installed on a computer device when you buy them.

• When you click on music you may have downloaded on your laptop to play it, windows media player will automatically pop up to play the music as that is what its for.

Digital rights management systems

• Digital rights management (DRM) is a systematic approach to copyright protection for digital media. The purpose of DRM is to prevent unauthorized redistribution of digital media and restrict the ways consumers can copy content they've purchased.
