Hi
For me MPEG4 video does not play in synch particularly in the larger formats or higher framerates.
As an example....
If I load a 20 second MPEG4 H264 1920 x1080 60fps clip.
It indicates 20 seconds above the clip in Timeline mode and shows 20 seconds in Storyboard mode. The clip looks perfect...until I play it. (in preview).
The soundtrack plays in 20 seconds
The visuals play in 45 seconds
So no way can it be edited in VP.
Is it VP or the PC? NCH say its the PC.Others disagree...
I am inclined to think it's the PC.
Added to this, the clip in question does not play correctly in Quicktime, (WMP wont play MPEG4) and it behaves like it does in VP. Jerky video and out of synch sound.
I find it better if I shoot in a smaller format at 30 fps, but it still not really usable.
i.e HD H.264 1280 x 720 MPEG4@30 fps.
If, now, I convert the video to MPEG2, the result is perfect. It edits correctly and there is no sound lag (although it is NOT the sound that is lagging).
For me this works.
