About MP4 files
MP4 is the standard video format for the web, phones and cameras. It usually contains H.264 or H.265 video with AAC audio.
Open Online plays MP4 with your browser’s player and shows resolution, duration and codecs.

Common questions
The video has sound but no picture. Why?
The file probably uses a codec your browser can’t decode, often H.265/HEVC. Converting it to H.264 with aintob.com usually helps.
Is the video uploaded for playback?
No. Your browser plays it directly from the file on your device.
