Format FLV
The Flash Video format was developed by Adobe Systems in the early 2000s to accompany the rise of the Flash Player. This format became particularly popular due to its adoption by early video streaming platforms, notably YouTube in its early days.
FLV uses video compression that allows for relatively lightweight files while maintaining acceptable quality for online streaming. It supports various video codecs such as Sorenson Spark, VP6, and H.264, as well as audio codecs like MP3 and AAC. This versatility made it a preferred choice for multimedia content distribution on the Internet at a time when connections were more limited.
However, the rise of mobile devices, particularly Apple's iPhone which did not support Flash, marked the beginning of the decline of the FLV format. Recurring security issues with the Flash Player and the emergence of more modern technologies like HTML5 gradually led to its abandonment. Although the format is still usable, Adobe officially ended Flash support at the end of 2020, making FLV largely obsolete for new projects.
Today, although some software and players still allow FLV files to be played, the format is mainly maintained for archival purposes or to support older systems. Content creators are now turning to more modern formats like MP4 or WebM, which offer better cross-platform compatibility and superior performance.
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.
