How to slip sync and cut audio of a ‘sync’ clip without cutting the picture
Hi there all… Basic non linear editing technique – done on film, avid, fcp7, GV Rio – and even video without the slipping sync aspect: Can anyone tell me how you can cut the sound of a “sync” clip(ie a clip with sound and video recorded at the same time) whilst not cutting the picture…so cutting, lifting out sections. But then also, moving the resultant sound sections around under the picture (“slipping sync” on film) independently of it. So there needs to be some way of detaching sound from picture in order to do this… Have tried a few methods like clip – break apart clip items …but can’t seem to get it to happen.
Would love to hear from anyone who has the secret!
Best regards,
Michael

You can slip audio independent of video without detaching it. See MacBreak Studio #345: https://youtu.be/v1nhaFYckyo

Hi there Joe, thanks; yes I came across that one…but is not quite what I am trying to do. Imagine a similar shot to the one he deals with but much longer. You want to cut several of those underwater breaths out over the shot, and then butt all the remaining sound segments, up to each other – thus slipping sync within one clip, to get the smooth bubbles sound…can fcpx do that?

…I’m finding that even when I detach the audio I still can’t manipulate it (cut or move it) independently of the picture….

You can stash audio and it is a separate clip. Or, match frame and connect an audio only instance of the clip and edit it in a secondary storyline.
Detach audio, should work though. Can you send a screen grab of the area you are working on?

Hi there Jeremy, thanks for your thoughts. I played around all afternoon with loads of ways of trying to allow the sound to be manipulated separately from the video…expand audio, expand audio components, Edit – Lift from Main story line and delete pic, leaving a slug and the sound, (couldn’t make work)
In the end this apple site suggested the route I used which allowed me to edit the sound without touching the picture…

As in Final Cut Pro 7, you can deliberately move audio out of sync in Final Cut Pro X if you wish. Control-click the clip and choose Open in Timeline from the shortcut menu to open the clip in its own Timeline. Then slip audio with sample-level accuracy.
….Except the option is now just “open clip” from the top clip menu…is not in the timeline one. So then you have the clip in a kind of parallel universe on its own, where you are able to make cuts in the sound and pull it around…so that for instance, you could cut dialogue without affecting the picture… Then I am not quite sure of the process yet but I clicked on the left chevron to the left of the name in the top of the time line (as a wild guess!) and was presented with the clip in the timeline at the end of the edit, with the cuts in the sound made but no cut lines visible in the wave form line, as if FCP had created a new clip according to the cuts…
So that was the most reasonable work around I could find.
Another peculiarity I have found was that you can’t pull the audio across the cut for a sound mix on the same line… but I found that ‘expand audio’ from the time line clip menu put the sound on two tracs (like you would have had to have done on 16mm) and then was able to allow the overlaps to be pulled out to make a mix….
Any improvements on both these work arounds gratefully received…
Best regards,
Michael

You have to think about this very differently than other editors. There is no reason, if you lifted from the main storyline, deleted the picture, and then moved the sound that it couldn’t work which makes me think that perhaps something isn’t being performed correctly.
Try this: Shift-f from a clip on the timeline. Hit command-2 to switch to audio only, hit q to connected the audio only clip. You now have an audio only clip that is fully manipulatable separate from any other clip. You can slice, dice, trim, nudge, move, anything.

This seems pretty easy. Drop picture in place, without sound. Do a separate edit connecting sound to picture at the head, so now you’ve got your clip both sound and picture in place. Chop away at sound, re arrage as deired. Once finished messing with sound, select the edited sound and picture, opt.-G, make it a compound clip and bada- boom- no?

Hi Mark, just read your tip… seems like an elegant little work around…let me try it and get back to you…

Hi there Jeremy, Thanks so much for your tip…I think I tried you method and have got it to work a few times now, with modifications:
1. Hit Shift + 3 / audio only – from the timeline menu (otherwise I bring pic and sound in with the edit despite the audio only step later…and I can’t get rid of the pic without doing away with the sound)
2. On the first frame of the section you want to work with hit Shift + F (match frame?)
3. Hit command + 2 (audio only?)
4. Hit Q to connect audio only clip to the main story line (drops in underneath the orig. audio role)
5. Keep the original audio in place – just pull down the level to mute it – since if not the sound you are cutting on the role below gets sucked up into any gaps which you can’t then move it from – However this is not problem at all and acts as a reference and sync check. So now you have a cuttable audio track(role?) below the original sound in the time line which you can cut and pull around as you like in a totally non linear way…and at the same time, enjoy FCPs own sync relationship with the attachment aspect to the main clip…
So that is were I am at at the moment with cutting sound. I have spotted that you just pull the sound tracks past each other in order to get at the extensions…which FCP shows as separate tracks/roles.
Still to work out exactly what I am doing(!) but ‘parrot fashion’ as in the above steps seems to work so that is a relief!
Thanks again,
Michael
