Premiere pro cs3 external recorded sound out of sync

[Jon Gulbrandson]

I had a similar issue once.. I recorded an event (over 25 hours DV footage) and used two portable audio recorders to capture audio in different locations..

In post, I put it all together (it looked and sounded great) but I also had that sync issue…

because the final edit was 2.5 hr long, i had to chop up the audio .wav about 10 times for each of the recordings, and sync it in the middle of each of the little ‘clips’ of audio…

I just assumed that the recorder captured the audio at a different.. speed.. or “frame rate” so to speak.. so no matter what, premiere is going to see that the video is 10;00;00, but the audio for the same exact thing is really 10;02;00…

I have no idea why.. but.. i also had to chop it all up to get it to match..

Just re-read your post…. it’s out of sync on export? hmm… try using adobe media encoder if you’re using Export>movie… that might work..

umm… otherwise, you may have to convert the audio to a different format…

Thank you Jon,

That is exactly what I had thought and that’s why I tried to dig around to see if there was a setting or configuration that would adjust the sound file for me.

But I have not found anything. Now I thought I fixed the syncing problem by chopping up the sound but in export the sound is out owf sync again. Which makes this a nightmare- if I can sync in premiere but loose it in export.

I am hoping there is a configuration issue- a rookie mistake somewhere in my file outputs.

I have heard of timecode issues and that your diplay timecode or display in general can be off ( I acn’t remember the specific thread). That thread said if you do not have your timeline audio display in the correct format you will get syncing problems. That makes the most sense.

There has to be a way to sync this sound. I am simply not doing something correct. 🙁

I could simply try to splice it all together but I want to discover the underlying issue and solve this problem for good- because i am going to be doing this often now.

Any help is truly appreciated.

Thank you

Umm…

Try diagnosing general premiere problems…

I know that I did have some crazy problem when I was trying to output my audio/sync project.. and I ended up trying a whole bunch of things.. but clearing the Windows temp files actually fixed it.. (sounds stupid, i know.. )

otherwise.. try using adobe updater to see if you have the latest version…

otherwise.. try rendering the sequence by pressing “enter” and then watching it and see if it’s still sync’d…

Otherwise.. (if you haven’t already done this) try exporting in a variety of different codecs… or give the Export>movie thing a shot….

the only other thing I can think of is maybe your dropping frames on export… not sure if that’s possible, or how to fix it exactly..

I know I might just try dragging some transparent video onto the timeline and adding a timecode to it.. just to see what happens…

sorry i can’t be of more help

Soundbooth or Audition might do a better job with your audio. Open all video clips and export audio as 48,000 Hz/16bit and use those audio files to replace the ones in Premiere.
