MP4 (abbreviated as MPEG-4 Part 14) is the most popular media format these days. It is supported by almost all modern devices: computers, mobile phones, tablets, etc. MP4 is a container format that allows you to combine audio, video, subtitles, and images in one file. It is a lossless compressed file format, which makes it ideal for editing as it does not lose quality after continuous editing and saving. MPEG-4 not only provides a process for compressing audio and video but also supports their high-quality playback through streaming.
