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.

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

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

[James Bayliss-smith]

Hi Daniel, based on my setting what do you think I wasn’t doing properly? I will never learn if I don’t understand.

Thanks

I have just done a further test, this time leaving the frame at 1920 x 1080. No juddery playback, no audio out of sync. I will use this one. But it still bugs me, why was I having these problems. Is compressor just not very good? Is it a bug?

Any advice and guidance much appreciated

James

[James Bayliss-smith]

I just tried compressing it using 48 kHz and still had the same audio sync problems.

Any ideas?

James

[James Bayliss-smith]

Sure I will do. What is the difference? Why do Vimeo want 44.1 and FCP 48?

[James Bayliss-smith]

I am going from 48 to 44.1 because Vimeo recommends that. I don’t know why but it is for Vimeo so I figure go with the settings they want? I can’t post a link yet but will do soon.
