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 MKV

The Matroska Video format is an open-source multimedia container format developed in 2002 by Steve Lhomme and the team at the Matroska project. Inspired by Apple's MCF (Multimedia Container Format), it was designed as a free and flexible alternative to existing proprietary formats.

MKV is distinguished by its exceptional ability to encapsulate practically all types of modern codecs in a single file. It can contain multiple audio tracks, subtitles, chapters, and metadata, making it a preferred choice for HD movies and multilingual content. This versatility is particularly appreciated by the VLC media player community, which has adopted it as one of its preferred formats.

One of the main advantages of MKV lies in its robustness and recovery capability in case of file corruption. It also excels in handling streaming streams and supports 4K/8K content, HDR, and advanced audio technologies like Dolby Atmos. However, its primary limitation is its lack of native compatibility with some mainstream media players and mobile devices, sometimes requiring additional codecs or software installations.

Although the format is widely used in digital content distribution and Blu-ray ripping, its open-source nature and flexibility also make it a popular choice for independent content creators and digital video enthusiasts. MKV continues to evolve with new multimedia technologies, maintaining its position as a reference container format for the storage and distribution of high-quality video content.
