5 frame audio lag on timeline and in render on s

PostFri Dec 02, 2022 11:12 pm

Hi,

I have source audio and video from a camera (25fps video, 48 kHz audio). When I import it into Resolve, it's fine. When I put it in a sequence and edit it, it's fine.

When I put that sequence into another sequence then the audio lags by about 5 frames.

I don't have voice isolation or dialog levelling switched on. I am doing some noise reduction, and stereo fixing switched on, but even with those off the same thing happens.

There's no drift - it's 5 frames out from the beginning to the end.

You can see that the audio waveform is a few frames out when you compare the two images - the speaking starts at frame 24, when it should be 19. Of course, I can shift it manually, but I'd like to understand what's happening.

Any ideas would be really helpful!

I've seen others report audio weirdness when using nested timelines.

My advice is...don't. Copy/Paste the clips into the main timeline instead of nesting.

Thanks Jim!

Hopefully somebody from BM will take note and fix it in an upcoming release. It would be a shame to give up on such a useful feature.
