Nice.

I separate audio from video in all of my projects.

One reason is that I have found that some video sources produce output with the audio up to 500ms out of sync with the visible action, so all of my video recording sessions begin with a synchronization clap.

This video shows a way of doing so that is very handy.

I have to do exactly the same, my webcam and mic record with slightly different starting lags. Annoying but easy to fix!

Thank you for watching :slight_smile:

I can’t find More when I right click on the audio or video track in timeline. What am I doing wrong? I have the latest version of Shotcut installed.

On later versions of Shotcut just Right-Click on the video clip and select the “Detach Audio” option.

is it possible to detach audio on multiple clips at once?

hi Mox601, I do not believe so. Its a per-clip job to detach all clips. If the clip starts as one long clip you can detach befroe you start cutting, that might help depending on what you are trying to achieve.

Long time no see

hello :slight_smile:

Thanks for sharing. Keep up the good work.

After I detach the audio, how do I lift a portion of the video without also lifting the corresponding (detached) audio? (Essentially, I want to keep that audio track, while switching to the video from the “second camera” which on the track below.)

BTW, in case this makes a difference… the second camera also has detached audio, and I actually want to continue to hear the audio from both cameras, regardless of which camera’s video I choose for a given moment.

Very helpful tutorial

I made a quick demo of what I think you are wanting to accomplish; see if this answers your question:

That’s great, thanks, and thanks for going through the trouble!

Yes, you’ve correctly understood my goal. The answer, apparently, was to get rid of the clip you don’t want some other way, rather than using the “lift” function. You called it “delete” but I think it might have been “cut”? (Because the only “delete” function I see is ripple delete, which wouldn’t have left the gap). I don’t know what key you hit for that deletion, though… and maybe it doesn’t matter… but I don’t know if there’s any difference between using the delete key (which is not the same as the ripple delete function), the “cut” command from the control-click pop-up menu (which shows an underlined T implying there’s also a way to do it with the T key though I don’t know how), or the “cut” command from the Edit menu (also invoked with command-X)… maybe they all do the same thing…?

Though regardless, I’m not sure what other ramifications there could be from using such a cut or (non-ripple) delete operation rather than “lift”. Since “Lift” and “Cut” are two different operations in the pop-up menu, there must be some significant difference. But I haven’t looked in the docs for this one yet.

Thanks again!

Correct, I did not use ripple-delete, but just hit the delete key to delete the clip without moving the others.

Delete or backspace key without shift IS Lift.
Cut is a ripple delete that also copies to the clipboard.

re: “Delete or backspace key without shift IS Lift.”

I wonder what I did wrong then. When I lifted e video clip, it disappeared form the timeline as I’d expected, but the detached audio associated with it disappeared as well (leaving only the second video track and the second detached audio track).

Ah - I had been wondering about the exact meaning of “Lift” - thanks for the clarification!
