Music Video - Trouble Perfectly Syncing Video to Audio in Premiere Pro 2.0

Hi -

Is it possible to move an audio track by a quarter frame at a time? ie. I don't see why audio tracks have to jump by a frame when you drag/drop them.

I am editing a music video. I have an audio track with a 40meg wav file. Then I have a 3 min video track.

Does anyone know how I can increase my precision?

-Trevor

PS - I am filming the guy rapping in 24P advanced on the DVX100B.
 
Do you have Adobe Audition? With that you can first do a cut of the footage in Premiere (just try to sync as best you can) and then export. You can then open it in Audition and move the audio around to fit the video better.

aside from stretching the timeline out I haven't found a way to be more precise in premiere

OK Thanks.

Maybe I am being a bit too picky. ie. The guy who i was doing the video for was sitting right beside me - and of course he is looking at me zooming in and how the wav file peaks are slightly off - and then he's like "IT's totally off" - but I wonder to myself if he didn't see everything zoomed in and just looked at the video if he would have had a different answer.

Anyway thanks for the response.

OK Thanks - I'll look into that.
 
It used to be an issue, when capturing extremely long clips, the sound would start to drift. Maybe try shorter clips?
 
Yes, it's possible to move the audio track by small amounts. First, the audio track needs to be unlinked from any video track. Then, click on the twirlie in the upper right corner of the timeline and select "Audio Units". Then, turn off the snap function which is an on-off button just under the digital time display in upper left corner of the timeline. Once you've done that you should be able to move the audio track in very small amounts. The more you zoom up on the timeline, the finer the movement.

Thanks Dan! I was able to line up the mastered audio track to the 1st video clip of the guy rapping perfectly. But - now I have a new problem. I can't figure out how to sync up the other clips to that precision. (each clip is a 4min version of the song being rapped from start to finish)

The Problem:

CLIP #1 - Frame 1 - 25% through the frame the first beat kicks in.
CLIP #2 - Frame 1 - 85% through the frame the first beat kicks in.
CLIP #3 - Frame 1 - 40% through the frame the first beat kicks in.
..
CLIP #8...


I need each 4min rap I record for the beat to kick in at the same time during the frame. Otherwise each one is going to be off. I have no idea how to do this though. Any ideas? (I can do a re-shoot no problem)

Nope - there's no drift at all - it's just that everything is consistently off by a few milliseconds.
 
I do not think that you can see a few millisecond synch issue.

In the days that we used to manually synch audio to video on a flatbed film editing machine, it seemed that people could detect 2 frame errors easily and in which direction it was out (ahead/behind). One frame was just determinable but difficult to know which way it was out.

Are you sure it is not a monitoring and sound card issue?
