MPEG-4 Video File

File extension .mp4
File category video
Description The MP4 files (MPEG-4 part 14 files) are the multimedia files which are used with multiple stations and video players simultaneously, they can store not only digital audio streams and digital video but other suitable amounts of data like subtitle tracks. MP4 video format is an extremely common file format due to its very own container format and it is also used with multiple platforms such as iTunes, PlayStation, and portable PSP as well. 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 great aspect 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 the streaming rather than sending video or audio information. MP4 files can be used to store audio streams and, in addition, text information, subtitles and still images while MPEG format can’t do this, anyhow the processing of data into MPEG-4 part 14 requires the use of private streams such as the use of hint tracks to include the information.

Description AVI basically stands for Audio and Video Interleave, it has an extension written as .avi and users use this very format to store audio and video on their PC which was developed by Microsoft in 1992 for its Video for Windows project.

Technical details AVI format uses the support of Resource Interchange File Format (RIFF) where the whole 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 and the second chunk gets recognized by the movi tag and it contains the actual audio and visual data which makes up the AVI movie. It uses less compression rather than the MOV and MPEG file formats.
