Recently, I’ve noticed my exported videos have audio that starts in sync but gradually lags behind the video upwards of 5-6 seconds by the end. From what I can tell, this isn’t an issue with the frame rate (I record at 60fps constant bitrate via OBS). This only happens on long videos that have cuts in the middle of the video. Videos that just have the beginning/end cropped are fine. There’s no issues with the playback in Shotcut, everything is in sync.
I’m about to pull my hair out, I’ve had to scrap 4 days worth of work because of this issue and am falling behind schedule, so any help would be great, thanks!
