#QTW 2.0 and sync

Just wondering if anyone's having problems maintaining sync with QTW 2.0whatever. It seems like on playback on lesser systems, it keeps the frame rate steady, but it skips ahead and behind on the audio to try to keep things in sync. I can see how it's great not to skip frames, but there are times when I'm going to want it to skip frames to keep in sync with the audio. Is there a way to modify Apple's QT player to skip video frames if behind…. Arnold Serame

If anyone would know, he would… Hope this helps, Tim Liebe

Tim, Arnold, One of QTW's main design tenets was to always drop video frames to keep in synch with audio during normal playback. Unfortunately, Apple took the project back in house last year and have been making changes to it since before v2.0 was released. If you want to get a more informed answer, I suggest posting it on the MACMEDIA forum to Paul Charlton. Sorry I can't be more precise on this. Nels Johnson, San Francisco Canyon Company

Thanks for the quick reply and pointing me in the right direction. Apple has their stuff so spread out over CIS — they're even worse than Microsoft in this regard. (I can't believe I'm typing that last sentence…) <g> Arnold
