How to ungroup the audio file of a video

Al_Korzonas wrote on 10/27/2025, 4:58 PM

The audio and video from a cheap digital camcorder are out-of-sync. The video is a fraction of a second behind the audio. How do I ungroup the two? I tried the expected "select both, right click, Track Group>Ungroup Selected Tracks" but Ungroup Selected Tracks is grayed out.

I found a stupid way to do it: duplicate the audio track, then mute the original audio track and then I can slide the duplicated audio track around. Then I can delete the original audio track and group the video and duplicated audio tracks.

There should be a more elegant way to do this.

If you were to host a clip so we could try it ourselves it would help solve the issue?

Select the events (not the tracks) and press 'U' on the keyboard to ungroup.

Or press Ctrl+Shift+U to ignore all event grouping (there's also a button in the transport and editing bar below the timeline to do this).

To group again, select the events and press 'G'.

The right click goes on one of the events, not the track. And if the the two are grouped, you only need to select one to ungroup them.

Sorry, I don't know how to host a clip. I have a workaround for now and hours of video to edit, so maybe I can learn how to host a clip when I'm not as swamped. (Also, I'm not using the audio from this camera for any of the multicamera edits I'm doing, so it's really just a curiosity.)

I think the confusion is that tracks can also be grouped. The track "ungroup" option would only be available if you had previously grouped the tracks together. That is useful if you want to organize a section of tracks that are for a certain purpose and be able to minimize them to a single entity on the timeline.

But it sounds like you're wanting events on the timeline ungrouped. As was mentioned, just select them all and press "U". Or you can select a bunch of events, right-click one of the selected events, and choose Group - Remove From.

What I've got is that I've dragged and dropped a video from a camcorder into the timeline. It consists of a video track and an audio track. The two are slightly out-of-sync. But I can't slide them in the timeline independently... they are always together. I tried selecting and ungrouping, but Ungroup is grayed out. The only way I could ungroup them was to duplicate the audio track, then delete the original audio track. Now I can slide the audio track independently of the video track and sync them. I was wondering if there was any way to ungroup them without this silly duplicate-and-delete exercise.

@Al_Korzonas, after dragging to the timeline, click on either the video or audio event and press "U". Then you can move them separately.

Or click on the "Ignore Event Grouping" button below the timeline. With that option turned on, you can move them separately.

Or use a script to change the "offset" of the audio event to get them back in sync:

@Al_Korzonas I think you haven't understood the difference between Event Groups and Track Groups.

When video and audio are "glued" together, they are in the state of Event Groups.

To ungroup them, please click:

Or just press "U" on your keyboard.

As for Track Groups, they are there for you to organize and collapse tracks.

@Al_Korzonas Maybe this can help to clarify the terminology used in VEGAS Pro.

This is a track:

This is an event:

You have to click on the event to select it, then press U on the keyboard to ungroup:

Or right click to go to "Group > Ungroup" as zzzzzz9125 has indicated. Then you can move the audio only.

A red indicator will appear on the audio event to show how much it is out of sync with the video.

@Al_Korzonas Could you show us (screenshot) how much the audio is out of sync?
