avi AVI (Video)

File extension .avi
Category Video File
Description AVI is short for Audio Video Interleave and as the name suggests it is a file format that contains both audio and video data. In the early 1990s Microsoft decided that they needed a file that could store both audio and video data in one single file and they decided that the file should be high quality which also meant AVI files tended to be large in size. AVI files exploded in popularity, so much so that for a long time they were considered the standard Audio Video file format.

Technical Details AVI files tend to be larger in size than other popular audio video files such as the MP4. This is because a lot less compression is used than other file formats of its type. One benefit of that though is the quality of the file tends to be slightly higher. In fact, an AVI file is often known as a lossless file format because the type of compression used means there is absolutely no reduction in quality. Given Microsoft developed it, it's perhaps not surprising that AVI files can be opened easily using Microsoft applications such as Microsoft Media Player but tend to be more difficult to open on operating systems that are not Windows. In fact, users often have to install codecs to be able to run AVI files if they're not running a Windows OS.

File extension .mp4
Category Video File
Description MP4 files became popular at the turn of the century when Apple announced the launch of the iTunes platform and stated that the media that would be downloaded by users would be in the MP4 format. MP4 files contain both video data or audio data or both and were built with size in mind. They are split into two distinct parts - audio and video - and both parts are compressed differently. It's this design that makes the format small in size and is the reason they are the de-facto file format for Internet audio/video downloads as well as being the file of choice for Apple.

Technical Details An MP4 file is different to an AVI file in that it uses lossy compression rather than lossless. Having said that, the overall reduction in audio or video quality is negligible and that's mainly because the compression used, whilst lossy, is of the highest standard and is done independently. I.e. the audio uses AAC compression which is about as good as audio compression gets whilst the video element is compressed using MPEG-4 standard which means the picture quality is still high. MP4 files tend to now be more popular than an AVI file as they are much more universal, that is to say that they can be played on almost any device or OS.
