Microsoft Audio/Visual Interleaved

File extension .avi
File category video
Description AVI stands for Audio and Video Interleave. It has an extension written as .avi, and users use this same format to store audio and video on their PC, which was developed by Microsoft in 1992 for its Video for Windows project. It allows the simultaneous playback by keeping video and audio into a single file. The simple architecture of .avi format will enable it to run on various operating systems such as Windows, Mac, Linux, Unix. It is supported by multiple web players as well.
Technical details AVI format uses Resource Interchange File Format (RIFF) support, where the real data is stored into chunks, and each chunk gets recognized by a FourCC tag. Out of these individual chunks, the first one can be recognized by the hdrl tag, and it can decode the chunk containing metadata for the video. The second chunk gets identified by the movi tag, and it includes the actual audio and visual data which makes up the AVI movie. It uses less compression rather than the MOV and MPEG file formats.

MPEG-4 Video File

File extension .mp4
File category video
Description The MP4 files (MPEG-4 part 14 files) are the multimedia files used with multiple stations and video players simultaneously. They can store digital audio streams and digital video, and other suitable amounts of data like subtitle tracks. MP4 video format is a widespread file format due to its very own container format. It is also used with multiple platforms such as iTunes, PlayStation, and portable PSP. It is also a popular file format for streaming over the Internet. For instance, YouTube videos have MP4 extension.
Technical details The technical details of MP4 files differ in significant aspects and are unique as well, first released in 2001 under ISO/IEX 14496-1:2001 standards. It uses an AAC encoding to wear off unauthorized users from copying the data. The main purpose is streaming rather than sending video or audio information. MP4 files can be used to store audio streams and text information, subtitles, and still images. At the same time, MPEG format can’t do this. Anyhow the processing of data into MPEG-4 part 14 requires private streams such as the use of hint tracks to include the information.
