I made some long (over 90-minute) Final cut programs into Quicktime movies. The .mov files play perfectly in sync throughout when I play them directly off a computer's hard drive. But when our web guru tried to stream them from our server, he found that the audio drifts out of sync. Just to recap: Final cut Pro - program stays in sync. Quicktime file playing on hard drive: - program stays in sync Streamed from server - begins in sync, then drifts out of sync! What kind of troubleshooting should we do to isolate the problem? If the trouble only occurs when streaming, then is the server to blame? the QT movies are Sorensen 3, keyframe every 300 frames, 15 frames per second, with audio RMA 4:1, 32 kHz 16-bit mono. Any advice appreciated.
