is it ok some videos on Quicktime time not to have sound just a high beep that cannot be stand for much time and on vlc they play ok ! the videos are mp4 .
 
It's very possible. .mp4 is a container so audio/video codec within can vary. Perhaps it's an audio codec used there that apple didn't implement support for.

Have you installed perian? Makes quicktime able to play a lot more formats.

Still Quicktime player X isn't as thought out as mplayerx, but at least it enables quicklook for lots of more formats.
