Hi guys, I've always found syncing external audio to video to be rather painless if a little tedious. However, recently after dragging the audio into a new project and lining up the clap on the waveform, it looks out of sync. After double checking that the clap was right on the waveform I played back at lower quality, did a render and still looks like it's out of sync just slightly. I then compensated by dragging the audio back about 10 frames, and it looks in sync but the waveform is blatantly not in sync with the clap when I move frame by frame. Any ideas?
