01:31 pm - Video editing question
I'm making a video for the Eldritch Skies kickstarter, and Alice is doing the editing. Using various freeware and trialware editing programs, she ran into one problem - the video now looks great, but the sound has been shifted just a bit, so it no longer matches up with lip movements. Is there some way to fix this? What looks to us like we need is a program to be able to separate out and slightly shift the sound track. Is that possible? Is there freeware or trialware to do this?

Our other option is to start again with another editing program and hope that this one doesn't shift the sound, but that means losing a number of hours of work, and would deeply suck. Does anyone have any advice?

Some video editing programs will actually let you decouple the audio track from the visual and move it like a clip. I don't know if yours will, but it's a thought.

John has unfortunately understated the problem. It appears that the sound and video pickups occurred at somewhat different rates, rather than the sound shifting in a predictable direction. I did try decoupling it and re-adding, but that just made things better in one place and worse in another.

Meh. I'm hoping we don't have to re-do the whole thing.

Would it be possible to split the sound and the video into smaller pieces, and then align each sound piece with its corresponding video piece?

I use Sony Vegas Movie Studio (not freeware, but it has a trial period). It lets you split the audio from the video and then edit them separately. That would let you move the audio.

First you would right-click the audio track and select "Group-Remove from" to separate it from the video part. Then you could move the audio track.

If the problem appears at the last stage of converting your working files to a DVD, that's a common problem in converting AVI's, etc to DVD. I use a freeware program called DVD Flick. Buried under the audio settings for the audio for each track there is a checkbox marked "Ignore Audio Delay For This Track". Checking that usually fixes the problem. I think it's basically a problem caused by the fact that .mpg is an incredibly archaic file format. I never have this problem when I convert to .m4v

If you're still interested in video editing, you might want to check out Lightworks which is free, opensource, and reputedly pretty nifty.
