Audio Sync Problem
I have about an hour of video that I’ve divided into 10 parts. Each of the parts are mpeg files that I import into Premiere Pro for editing. When I take these mpegs and drop them onto the timeline, the audio and video lose sync. The audio might be perfect for the first few minutes, then become unsynced half way through and remain unsynced for the rest of the video.
The original mpeg files have perfectly synced audio. When I preview the original mpegs in Premiere they are still synced. It is only when they are placed on the timeline that they lose sync. I thought that this might only be an apparent error (due, perhaps, to my system being slow when playing the long timeline), but rendering an unedited timeline creates an unsynced video. Normally, I would simply unlink the audio and video to correct this, but the first few minutes are synced perfectly. Unlinking and moving the audio, obviously, would then leave the first several minutes unsynced.
Any ideas? Has anyone else had a similar problem?
