Format WEBM
WebM format is an open-source multimedia container format developed by Google in 2010. Initially created as part of the WebM/VP8 project, it was specifically designed to meet the needs of web streaming.
Technically, WebM encapsulates videos compressed in VP8 or VP9, as well as audio in Vorbis or Opus format. This combination provides efficient compression while maintaining high visual quality. The format is based on a simplified version of the Matroska (MKV) container, giving it a robust and flexible structure.
One of the main advantages of WebM lies in its royalty-free nature, allowing usage without royalties, unlike some proprietary formats. This feature, combined with its excellent compression rate, makes it a preferred choice for HTML5 video, particularly for platforms like YouTube. It is particularly effective for live content streaming and video on demand.
While the format is widely supported by modern browsers like Chrome, Firefox, and Opera, its main limitation remains its limited compatibility with Safari and some iOS devices, sometimes necessitating the provision of alternatives such as MP4. Despite this, WebM continues to gain popularity, notably due to its streaming performance and excellent quality-to-size ratio, making it a promising format for web video.
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.
