The media player that comes with Ubuntu is unable to read *.mp4 files, so you have to install a media player that can read these special codecs, I suggest VLC.To install it,method 1:run the following command from the terminal: sudo apt install vlcmethod 2:open ubuntu software (press the Windows button then type 'ubuntu software' in the search bar) then search for VLC and install it.
If you tried to put into practice our step-by-step guide on how to use VLC to convert MP4 to MOV, but something went wrong, you can always use an alternative .mov-to-.mp4 converter. Movavi Video Converter supports a large number of media formats and can process your files in no time.
- I have a large collection of videos in .mp4 format that for some reason Quicktime player doesn't seem to like.

MP4 file format seems one of QuickTime player supported native video formats. But the weird thing is that QuickTime will reject to open some MP4 files created from GoPro, iMovie, Final Cut Pro, and more. The error message goes like, \"The document 'xx.mp4' could not be opened, A required codec isn't available\", \"Unsupported format or damaged file\", \"The file has no audio or video streams\".
It happens several times that the MP4 file you are trying to play uses different codecs and QuickTime fails to identify it, that time you can see the error \"The document 'xx.mp4' could not be opened, A required codec isn't available\".
So I made an intro using animation and it saves it as a .blend and I want it so save as a video like .mp4 or something like that.I've tried changing the codec because I tried opening the intro with windows media instead of blend. I didn't try all the codec's but I tried some of them.
