FCP 7 speed change crackle
Ok, so I updated everything and trusted Apple! Im using FCP7 and am on Snow Leopard 10.6.2.
I have been doing some edits that required me to sync up some audio. I was supplied the audio as raw film reel files (about 20 mins in length each) and also running at the wrong speed (23.98). So I set it all up in an FCP timeline and changed the speed of the audio files using the speed change option. After doing this the files all played fine direct from the timeline… but when exported (from pretty much
EVERY export option) the files always had a ton of audible crackle!!Anyone had the same issue and got a fix?
Cheers,
Tom. -

Audio doesn’t have a frame rate per se. It runs according to its sample rate. Try using Soundtrack Pro or Quicktime Pro to open one of your audio files and export it as PCM 48kHz 16 bit. Then see how that matches up with your video. You can’t do this from inside FCP. It has to be an external program.
