Stretch the timeline more than frame by frame?

Hi,

Can you stretch the timeline more than frame by frame? I recently shot a music video and sound and image simply won't match. On some shots if I move the footage one frame back it's too much, if I move the footage one frame forward it's too little.

thanks,

Rafa
 
Are you trying to edit AVI + MP3 material? If so, make sure you convert the MP3 to WAV format first.

I don't know the answer to your question though.
 
I'm actually trying editing mpeg with windows media audio...Should I convert it to WAV as well?
 
See cbrougham's post correcting my post on page 1 in the multitrack editing thread below for your answer to changing from frame accurate to sample accurate. He mentions the source monitor but it's the same in the timeline.
 
Yes, I know you can stretch the audio timeline and that would help a lot if I was editing dialog, because I would actually be editing the sound as well. But with a music video that really doesn't help me, since if I move the entire audio track some parts will get better and some will get worst.
 
The problem I think it is, is that MPEG is keyframe-based and WMA/WAV are not.
If you don't want to convert the MPEG files to something frame-based like AVI, then you might want to try to convert your audio to an MP3 which is keyframe-based.

Can someone confirm this? In the meantime you can try the above.
 
Thanks, Ferdi. I'm going to give that a try. I have to get cineform at once. Editing 20 mpeg tracks is a nightmare.
 
I know man, I've been there. At first I never knew why my system had such a hard time with HDV (quad core overclocked, 4GB RAM). Then I tried AspectHD and knew I had to get it :)

I've also had a lot of problems with audio back then. I did a wedding in March and ended up doing all the audio in post using Adobe Audition because the audio was way off. So I converted my movie to AVI, which was very slow without AspectHD, and then exported my Audition's audo to WAV. It was so time consuming. If only I knew what I did back back then :)
 
yeah, either way you should be using sample accurate audio editing mode within ppro, and then of course, using codecs that arent keyframed is always a good idea if possible. ppro auto conforms the audio and video footage on import anyway, so you shouldnt have to worry about converting it, just switch to sample accurate audio and you should be fine.
