Hi, I’m getting this as well on a project where I have an mp4 on V1 and a Mp3 on A1. In my project, perfect sync is essential and I have found the audio to be in sync in the preview window but not synced on export. I found a workaround - advance the audio clip by 6 frames. Then export. Perfect sync. Then hit “undo” to continue working on your project if you need to.
I think it’s a bug. @Scam_Likely, could you try my workaround and report if it works for you?
PS not sure of your ability level, but to advance the music clip, go to the beginning of your clip (ALT+left arrow) then press Right Arrow 6 times to advance the playhead, then slide the clip to he right (making sure snapping is on (magnet icon), Thanks!
