Moving an AUDIO track by a fraction of a frame?

[przone]

We shot 3x interviews with multiple cameras.

When compiling the footage into 3 projects afterwards, one was perfect, but the other 2 had a minuscule shift.

If you played either audio with the people talking - it was perfectly synched.
However, running both audio tracks together (which is what I wanted to do), produced a slight - but detectable - reverb.
I looked at other discussions on here and there was a lot of talk about 'time units' etc - but no solution.If you have 2x video sequences on your timline, and they are 'out' by 1/5th of a frame - how can you rectify that?
How can you move one audio track 'along' by 1/5th of a frame to get a perfect sync?

Set your timeline to Audio Units either Wrench Program Monitor or hamburger menu timeline.

Now you can move an audiotrack 1/48000 of a second.

you can't. you used mics built into the cameras and the slight difference in distance between talent ( sound of their voice) and the science of sound traveling in space, without recording it with jammed timecode between camera, slate and recording mixer. Forget about using J an L cuts ( over lapping sound from one camera to another ) and just cut between cameras and use sound you got from each one.

You'll be the only one who can figure out what works for your cuts and coverage to fix the problem. If you got some 'reaction shot' ( coverage of someone nodding head while someone else on different camera is yappin, and then you stay on them and you want the sound to bridge that distance, you're pretty much out of luck ). It's not really an echo so much as the distance between mics and so on

I don't think I would hear a difference between 1/5 of one frame myself … so maybe you are over critical of your own outcome ?

The weird echo sound can probably be eliminated with adjustments to the audio files with audition etc.

when I was typing this Anne gave you the answer. How cool is that ???

Thanks for the replies  

Both cameras were identical and we used the same Audio Technica microphones with the same length cables (but the ‘speed of sound thing’ was way cool!)

I’m off to find the Wrench/Hamburger thing
