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 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.
