When I have audio and video tracks de-synchronized, is there a way to make them synchronous?

A workflow:

  • Add a video+audio track to a project;
  • Crop a small Event in the middle and remove the rest;
  • Uncheck Ignore event grouping option;
  • Drag one of the tracks sideways;
    Note the audio track gets reddish background to indicate it is not synced to Video.

  • Resize Video and/or Audio Events so that original start/end timestamps get lost;

Now I need to get Audio synced back to Video.
Obviously, dragging Video or Audio will not work as I have resized both Events individually.

How to get Audio back in sync, probably by losing cropping?
I'm aware about opening the Event in the Trimmer and re-dragging the Audio track from there.

  • I use Sync Audio to Video command from Vegasaur toolkit. Note that this third-party extension is not free.

  • @altarvic Thanks for a suggestion. Please consider turning your comment into an answer so that others can upvote it; just make sure you notice that Vegasaur is a separate commercial product. May 13, 2014 at 20:43
  • can Vegas set markers? If so set an audio marker and video marker before the desynching

  • @KvdLingen Thanks, but it will not work. Markers are tied to project's timeline, not to individual Events. May 14, 2014 at 21:55

This does it for me (see the screenshots):

  1. Set the cursor to the beginning of the audio event.
  2. Drag the beginning of the audio event with the mouse to the beginning of the original clip (note: the cursor is still positioned at the cropped beginning) (screenshot 2)
  3. Cut the audio event at cursor position (press S)
  4. Repeat step 1 to 3 with the video event (screenshot 3)
  5. Now you can easily synchronize video and audio by aligning the events (screenshot 4)
  6. Delete the beginnings. (screenshot 5)synchronizing audio and video
