I’ll definitely take a look at this, thank you very much.
The weird thing about the audio going out of sync is that it seems to happen whenever there are gaps with no video or slug covering it. For example, I will play my timeline, and if I have a 3 second gap between two clips, the audio will go out of sync starting at the second clip. If I fill it in with a slug it seems to be ok.
Thanks again for your help, it is much appreciated.
