Another post that's a mix of Audio, Editing and Restoration...

...hence my placing it in the general forum.

Here's my question:

I have a poor video clip, taken from YouTube. It's a classic film trailer, where the audio and video are horrible. However, I have a high quality rip of this film, even down to the same frame size. Therefore, my "project" is to do a sort of remastering job (not quite the proper term, I know) and make a new trailer that's faithful to the original in all respects. I've already done a bit of tinkering and know that it is possible and works nicely. There's just one issue (for now; probably more to follow) that I need help with...

The original clip's A/V is out of sync. In order to match things up properly, I need to know how much skew there is in the original clip. Is there any way to determine this in a more professional and accurate manner, rather than simply watching, guessing, adjusting and hoping that it looks better with each viewing/adjustment?

Again, I'm not great at wording things, but I hope you'll understand what I'm getting at.

Thanks for any advice,

Justin

is it a constant sync issue? if so, use the +/- keys in your media player to shift the audio and note the sync delay value when it is in sync

if it's a progressive sync issue, there is a length mismatch, and you usually have to either stretch/shrink either video or audio to match lengths

if there are errors/glitches you usually have to process and fix each segment

I'm pretty sure that it's a constant mis-sync. It's difficult to be absolutely certain 'cause of the poor quality.
