A common question is which is better, WebM or MP4. For example, for “mp4” and “webm”, which one has better image quality, which one consumes more space under the same conditions, and which one should be selected to convert or download the video for storage? There are several things.
What is WebM: An open video file format developed and published by Google. A subset of the VP8 format for video compression, the Vorbis format for audio compression, and the Matroska format (MKV / MKA) for the file format (container format).
MP4: One of the file formats for storing video data compressed in MPEG-4 format. MP4 is a format derived from ISO / IEC 14496 Part 12 developed based on the Apple QuickTime media technology file format, and has a structure that follows many of the conventional QuickTime formats.
