About the MP4 format
MP4 (MPEG-4 Part 14)
MP4 is a container standardised as ISO/IEC 14496-14. Inside there is usually H.264 or H.265 video and AAC audio, sometimes AV1. Almost every device and service accepts MP4, which is why most videos online are published in it.
If a video does not open or a site refuses to accept it, converting it to MP4 with H.264 is the most reliable way to fix the problem.
Best for publishing and sending videos - maximum compatibility at a reasonable size.
