editing 29 fps to 24 fps audio synch issues??

B

buddyreid

Hi everyone-
Finishing up work on my film. It was shot DV and edited in Final Cut Pro.
The total length of the project is over 2 hours.

I know it will never look like "film" without very expensive plugins...

My question is: If I bounce it down from 29 fps to 24 fps, will it go out of sync with the audio?


If so, is there a reasonable solution?

If not, are there any suggestions for minimizing the video "look"-- I know it won't look like film, I would just like to tone-down the camcorder harshness of the image.

I appreciate any replies-- thanks, guys.

Shouldn't. 24fps in video is just an illusion. Video always plays at 30fps; the computer just reorders the fields, repeating some and eliminating others to create the 24 look, but the frame rate hasn't actually changed.

If that makes sense.

Not something in which I am well versed.

I have only done it once and on that project we did it scene by scene. We generated visual and audio sync points (which were later removed) and I was able to time stretch the audio back into sync without much in the way of artifacts. Those artifacts that did appear I was able to patch without much effort.

thanks, guys--

i appreciate the feedback. any of you know any tricks other than changing frame rate to lessen the video "look" ?
i've googled and read a lot of suggestions, but was curious if anyone has had good results from any in particular.

This makes no sense to me, Alcove. Why did it go out of sync? Was it shot originally in PAL, maybe? I've applied a film look in NTSC video many times without a single sync issue, ever. 30 frames per second is 30fps, regardless of how the fields are rearranged...unless the software they were using wasn't well thought out.

Was the footage too fast or too slow afterward and by how much, do you recall?

It was about seven years ago and was a mix of Pal and NTSC footage in one file as far as we could figure out. The editor and I were cleaning up a multiple conversion disaster created by a number of others and we didn't have access to the raw footage. The project had passed through many hands on both sides of the Atlantic before it got to us. Some of it came from Eastern Europe, the Middle-East and Africa where they don't have the access to technology that we do. The footage was five seconds longer than the audio at the end of about 100 minutes; some segments were in sync just after moving them, others drifted slightly.
