Edit down source video, sped it up and audio goes out of sync
Nearly every time I edit a video and attempt to speed it up or slow it down, the audio ALWAYS goes out of sync with the video even though they are totally grouped together and move together on the timeline while ctrl-dragging. Is there some way to avoid this???
I wish I remembered this lesson prior to spending hours editing down to just the pieces I want of my source video, then highlighted it all and ctrl-dragged it in just a few seconds worth of timeline. I never saved my original and now I am thinking I will have to re-do all of my editing down in order to fix this (otherwise I’d be forced to sync “by hand” each of the dozens of sections of audio/video pieces).
Is there any easier way to undo what I have done when I can’t [ctrl-z]undo it and have saved over my main source file WITH the messed up audio? Someone tell me there is a way! 🙂
Any thoughts are appreciated, thank you for reading.

I believe speeding up and slowing down onl works with the video track in Vegas. Sony sound forge is able to stretch aiudio without changing the pitch. I’m not sure if the newer versions of Vegas have this ability yet. On a good note, Vegas is nondistructive as are most non linears these days so your original files are ok.You should be able to a marker where each video begins, select and remove a clip from the time line, then add it back in with the curser at the marker. It should come back in un stretched. Hope this helps, Danny Hays

Thank you for the reply Danny.
I am using Sony Vegas Pro 8.0, it does stretch both and stays in sync right after doing it, but then if I go off and mess around with something else and come back to it, it’s out of sync when it was completely untouched. Maybe it is just this version of vegas that does it, I don’t know. It will also stretch the audio but it is hard to describe the end result.. it adds “audio gaps” almost in it, it sounds like…
But most importantly, you mention I should be able to “marker” where each clip is at in the main source clip – how can I do that?
Thank you again,

Place the curser at the beginning of a clip in the timeline and hit the m key. It allows you to name each marker. So after removing a clip you know where to add the original clip, starting at the marker.

I see I see… but this is something I should have done originally and isn’t something I can go back and have vegas mark out for me automatically somehow, correct?
I guess that is what I am looking for.. which probably doesn’t exist 😛

Here’s a workaround to try.
Double-click the time-modified clip to highlight it.
Right-click and select “Open in Trimmer”.
Zoom out in the Trimmer window to show the clip as well as what’s before and after it.
Right-click on the highlighted clip in the Trimmer window, drag it to a new timeline track at the beginning of the time-modified clip, let go of the mouse button and select “Add across Tracks”.
The clip will now be shown in it’s original unmodified length.
