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 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.
