What is an MP4 file and how to open it in one minute?
A file with the MP4 file extension is short for an MPEG-4 Video file. This is a compressed file format that can contain not only video and still images, but also audio and subtitles.
MP4 files usually appear when you download a video from the Internet or use a DVD ripping program to save a DVD to your computer.
Files like this, which contain only audio, are sometimes saved with the .M4A extension.
