Format MP4
The MP4 format (MPEG-4 Part 14) is one of the most widespread video formats, developed by MPEG in 2001. Originating from Apple's QuickTime container format, it is part of the MPEG-4 standard and quickly established itself as an industry standard due to its versatility and efficiency.
This container format can encapsulate various types of data: video (mainly in H.264/AVC or H.265/HEVC codecs), audio (AAC, MP3), subtitles, and metadata. Its strength lies in its ability to maintain excellent visual quality while offering efficient compression rates, allowing for reasonably sized files. This makes it the ideal format for online streaming, video sharing on social networks, and digital content distribution.
MP4 enjoys universal compatibility, being supported by most media players, web browsers, smartphones, and tablets. It is especially appreciated for its robustness in adaptive streaming, notably with HLS and DASH protocols.
Its main limitations concern the file size, which remains significant for videos in very high quality, and the fact that some advanced codecs require licenses for commercial use. Despite these constraints, MP4 remains the preferred format for digital video distribution, combining quality, compatibility, and efficiency.
Format AVI
The Audio Video Interleave format was developed by Microsoft in 1992 as part of their Video for Windows initiative.
This media container allows for the simultaneous storage of audio and video data in a single file, interleaving them for synchronized playback. Its structure, based on the RIFF format, offers great flexibility in the choice of codecs used for compression.
AVI quickly became a video standard in the 1990s and early 2000s, particularly appreciated for its broad compatibility with Windows systems and its ability to maintain high video quality. It supports various resolutions and can contain videos encoded with different codecs like DivX, XviD, or MPEG-2, thus offering significant flexibility to content creators.
Despite its historical advantages, AVI has certain technical limitations. It does not natively support embedded subtitles, chapters, or advanced metadata, and it can struggle with videos over 2 GB due to its indexing structure.
These constraints, combined with the emergence of more modern formats like MP4 and MKV, have gradually reduced its use. Nevertheless, AVI remains widely supported by most media players and continues to be used in certain contexts, particularly for archiving uncompressed videos or compatibility with older systems.
