Subframe audio adjustments are undone when clips are moved

I'm trying to sync audio, I turn on audio time units to make the subframe adjustments and line up the clips perfectly. Once I'm done, I turn off audio time units, clip a few frames off the beginning and end of the clip so they aren't subframe. Then I group all the clips together. But whenever I move the clips all at once, the subframe adjustments are undone and it goes to the nearest full frame.

Is there any way to get around this? A setting that keeps this from happening. Or any sort of workaround, like maybe a way to export it once synced up and bring it back in with all the audio tracks still intact? Any help is greatly appreciated. Thanks!

I have been having the same issue for a couple of years. I'm sure it used to work properly in the past. It lets you slip or move the audio by sub-frame amounts, so surely that change should stick!

 

Cheers,

Mike

Line the audio clips up to the video clips.

You can move audio 1/48000 of a second. Video clips only one frame.

Ann is correct, but with a typo error I think ... don't group the file, link the audio files to the video file after setting sync. That should work for you, it's something I've done I don't know how many times.

Thanks, Neil. But how would I be able to link all of the clips together? When I try, it only allows me to select "Group" and "Link" is not an option.

OK I'm trying this link workaround, linking each audio file to one video file in  my cut and so far so good. Wish me luck, and thank you Neil!!!

Ack spoke too soon - they were staying in sync w/ move but reverting back on cut. Adobe, would be great to get this fixed!

Linking is for one item per track ... when I'm doing syncing of separate audio, it's one or more 'remote' audio and one or more cameras ... and if I'm doing manual syncing, I'm syncing one clip/audio-set per time. Which should allow linking.

 

The other time Link might not be allowed is if you have a link between the video and one or more audio tracks already set. Which, in including the camera audio as is apparent in your image, you do. So ... Unlink all, then Link.

Here's the thing - it should work as you describe, i.e. you move or slip the audio waveform by a sub-frame amount to line up perfectly. It appears to have worked. You can link it, snap the synced audio to a frame boundary etc, but when you MOVE the linked clips the waveform goes back to where you started. The sub-frame adjustment doesn't stick!

I did a feature doco about 4 years ago syncing sound from an external recorder. I was able to sync the audio a sub-frame amount to match the camera audio perfectly. And it stuck. Then somewhere in the updates since then I haven't been able to get the changes to stick. I've bought it up a few times on forums and with support with no joy - it's nice to know I'm not the only one in the world seeing the issue!

Neil, as a test, can you enable audio time units, zoom in and sync 2 waveforms together perfectly, link the clips, disable audio time units, then nudge the clip 1 frame left or right or just move it on the timeline and see what happens to the sync/waveform?

CHCK,

 

That's something I do several times a week ... and without troubles. So I can't replicate the behavior you and DevonW are getting.

Hi Neil,

That's super strange. For me (and Devon I think) when you move/nudge the synced clips the sub-frame audio adjustment reverts back to the nearest video frame point. I've tested and tested and there is no way I can get the sub-frame change to stick, after the linked section has been moved on the timeline. Even 'undo' doesn't bring the subframe adjustment back.

 

Cheers,

 

Mike
