Workflow

I captured HDV footage as ProRes 422 (Normal Quality) straight into Final Cut Pro.

I am using Compressor version 3.0.5

Why did you suggest I read the chapter on Frame controls? I understand that this is the most important part of compressor but did you have any particular reason in relation to Audio sync issues? I always use frame controls to de-interlace. I will read this chapter. I’m guessing it must have something to do with the ‘Retiming control’ as the timing of the audio was out?

Thanks for your kind advice

Because you said that you were unhappy with the quality of playback

How did you get it to compressor?

I just read the chapter on frame controls and there seems to be nothing in there that would make the audio go out of sync. Still a mystery

I got the video into compressor by exporting a Quicktime Movie “current settings” then dragged that into compressor

I have just realised something that may be of interest. Due to capturing a portion of one tape at a later date than all the rest I have realised that there is 1 clip in my sequence that was captured as ProRes (HQ) all the rest is just ProRes. I’m not sure why this would be a problem as I’m sure Final Cut 6 can handle different sources in the time line.

Hi Daniel, any ideas?
