44 khz -48 khz Audio

[Eric Susch]

It shouldn’t lose sync if you convert the audio to 48 kHz as Dave suggests. Actually it shouldn’t lose sync if you load a 44.1 file and render the audio, but FCP may be doing some funky math in the background on import, I don’t know. Best to convert to 48 kHz first.

The dialogue is getting off over time. If I sync the 44kHz audio to the 48 kHz it stays in snyc for a little while but gets off over time even after I convert to 48kHz. I think I need to do some sort of pulldown in order fix this, but I’m not sure how.

The compressor didn’t have the look ahead set far enough thus the distortion. We have the output set to -10db and was still distorting.

Were you shooting film? Or HD at 24 or 30fps? (as opposed to 23.98 or 29.97) If so then yea, you’ll probably have to do a pull down. Not sure how to do that with Final Cut. It’s been a long time since I’ve done double system.

If you’re shooting video then your problem is something else. When you say it’s “getting off over time,” how much time are you talking about, a minute? An hour? By how much?

Shooting SD 29.97. I can understand why the CD is off it’s not synced up to a word clock like our TV Audio board is. I eventually slowed the audio down from 100% to 99.999% with the speed adjustment and that has brought me to a very close sync. I don’t believe my problem was the actual conversion from 44 to 48, the Front of House board is not synced with our word clock.
