Jumpy jerky mp4's

[zinc]

I got an mp4 video file and when i tried to play it back through VLC player it was jumpy and jerky. So i decieded to play it through wmp and it played back smoothly but the audio was out of sync in wmp when it was fine in vlc i have installed the ffdshow and haali media splitter but playback in wmp still results in the audio being out of sync.

I ugraded to the latests version of vlc player and tried to playback the file and it was still jumpy i have played mp4's before without a problem so what can be wrong in this situation?

thanks

Just a guess, but you may have a corrupted file and VLC may be dropping frames to keep the video/audio in sync. Try playing back in MPC-HC and see if it also is out of sync. WMP isn't much of a player, IMO.

Have you checked the file with Gspot to see if anything odd shows there?

thanks for your reply redwudz i tried it in mpc-hc and it was also out of sync with Gspot nothing unusual came up it did say that the codec status was undetermined though...

i suppose it is a bad file but where i downloaded off people had left comments on the video saying it was good qaulity and so on.

Use MediaInfo instead, and post the information about the video here (blank out the file and path name, if you prefer). My guess is, it's an HD video, and your computer may not be powerful enough to play it correctly.
