Syncproblem solved:-) + A question!
Hi!
In mid March I posted here about a problem concerning bad audio/video-sync in Premiere Pro (both v1.5 & cs4). Post: Videosync-problem in Premiere Pro!
Unfortunately no one could help me, so I keept trying different stuff to solve this problem on my own. And finally, I found out what it was causing the video to play to slow. It was a program called “EPU-6 Engine”. This is a energy-saving program for my mobo (Asus P5Q Pro) where there are different modes for voltages and cpu-load (turbo mode, high performance mode, medium powersaving mode, max powersaving mode and auto mode).
When running in auto mode (which I was) the program automatically selected ‘max powersaving mode’ most of the time, including when I was using Premiere Pro. In this mode the cpu is not running at full speed (it’s set to -9% cpu load by default). This caused the video to play at a slower speed resulting in bad sync with the audio.
The problem was solved by either selecting “high performance mode” at which the cpu run att normal speed, or turning the “EPU-6 Engine” off. Hope this info can help somebody else.Now, I have a question: Why is PP acting like this in conjunction with the “EPU-6 Engine”. Because when playing the DV-clips in players like VLC, WMP there’s no sync problems. Is it that PP render video in a different (more complex) way? Just curious.

Good sleuth work! I’m glad you got to the bottom of it.
Yes, there is a considerable difference between simply playing back a video and editing it. PPro has to do more work when playing video on the timeline than a media player has to do when playing back a file on disk.
You can improve PPro’s performance by rendering the timeline.
You will also find links to many free tutorials in the PremiereProPedia that will quickly show you how things are done in Premiere Pro.
Cheers
