Sub-frame positioning for audio clips?

It seems when I am trying to manually sync audio, when I drag the clip, it snaps and doesn't let me freely move it as precisely as I would like. Sometimes this necessitates a chorus-like or flange-like effect when wanting to mix multiple audio sources.

It seems like the only solution is to extract all the audio tracks and prepare them in a DAW, mix them, and then put them back into the resolve NLE. Surely this is unnecessary.

Im using Resolve 14.0.0.078 on windows 10.

Just click on the magnet shaped tool in the toolbar. If it is not lit you can happily slip tracks. Zooming in will give you greater precision.

On the Edit page, use the sub-frame audio slipping commands (op+right, op+left). It's must also be possible on the Fairlight page, probably with greater precision, but I couldn't tell you how, somebody here no doubt can.

Unfortunately, those commands apply only to the Edit page, so there's currently a lot of switching back and forth between the Fairlight and Edit pages to accomplish many simple editing tasks such as this.

Yes, it’s awkward having to go back and forth continuously between the two for everything. Hope there’s a solution in the future that allows Fairlight to use commands associated with Edit.

Thanks for the feedback everyone.

Charles, just to clarify, the magnet is for snapping to video frames only. Even if you take it off, the audio still snaps in chunk sizes that can leave you with inaccurate audio alignment.

HOWEVER, the Alt-<arrow> solution gives you more fine-grained control than what the audio snapping seems to allow. I will be using that to "nudge" audio clips on the timeline from now on.

Yeah the fairlight thing has a long way to go in my opinion, but its a great start

Hello Terence. No snapping in chunks on my system. I am able to position the audio exactly where I want it by grabbing it and sliding. True it is not sub frame, but single frames with a read out showing a plus or minus frame position.

48000/24 = 2000. That's not really enough precision.

In the Fairlight page you can zoom in to sample level and move the audio by a single sample if you wish.

Sub-frame positioning is possible on the Fairlight page and Audio Clips may be moved by the sample if required.

The animated version of Jean Claude's image:

Actually, you *can* move audio clips in subframe increments on the Edit page, with the same accuracy as sub-frame slipping. Not at the sample level, but for syncing to picture, it's more than sufficient.

Quite true. If your primary visual objects and audio sources are close to you, syncing is straightforward. But as the subjects move away, as we are all aware in the real world, the sound will lag behind the audio noticeably. In the reel world, at least the virtual reel world of digital audio and video tracks, we could match the audio exactly to the video. I don’t do that exactly though as I think our brain might be happier with some of the real work delay in sound. You never hear the thunder when you see the lightning... unless it strikes you!

Just on that subject, it's amazing how our brains notice audio when it's slightly earlier than the video. Just because in nature, the sound never arrives first. We are far less sensitive to audio being late than being early. So if I notice bad sync and it's extremely close to the video, almost certainly it's because the audio is slightly early.

VERY USEFUL THREAD by the way - helped me as I'm trying to sync a bunch of singers, and +-1 frame is absolutely not fine enough time-resolution for audio.

How can I move audio AND VIDEO by subframes?

Video is frame-based.
