The VideoLAN Forums

I set the video filters, colour; sharpness and contrast on an mp4 file to enhance it, in VLC Media Player. I then Converted / Saved the the file in mp4 format. I turned vlc player off, then reloaded to watch the video and was delighted to see all the enhancements were present on the playback! Then came the bad news: I found the mp4 file would ONLY play on the vlc media player and NO OTHER media player!
Why should this be? It is obviously not a legitimate mp4 file in it's make-up. Vlc player can cope with it, whereas other media players cannot. I can only think something must make a radical alteration to the files make-up when enhancement filters are applied(?)
Clearly this is not good. I wanted to burn the file to a dvd in it's newly enhanced form. Where am I going wrong? What do I need to do to make the mp4 legitimately?

I just updated to latest version and was in the middle of watching an mp4 video and it is not supporting my mp4 files..

any suggestions?

What version?

I saved a file create in VLC as a .mp4 file but it only plays using VLC. Windows Media Player won't play it, the Windows Explorer does not make a .mp4 icon of the file and Twitter won't upload it. What is wrong?
