Description WebM is a video file format. It is primarily intended to offer a royalty-free alternative to use in the HTML5 video tag. It has a sister project WebP for images. The development of the format is sponsored by Google, and the corresponding software is distributed under a BSD license. MPEG-4 Part 14 or MP4 is a digital multimedia container format most commonly used to store video and audio, but can also be used to store other data such as subtitles and still images. M4A stands for MPEG 4 Audio and is a filename extension used to represent audio files.
Technical details The WebM container is based on a profile of Matroska. WebM initially supported VP8 video and Vorbis audio streams. In 2013 it was updated to accommodate VP9 video and Opus audio. Audio-only MPEG-4 files generally have a .m4a extension. This is especially true of non-protected content. M4A is often compressed using AAC encoding (lossy), but can also be in Apple Lossless format.
