Pro Res HQ in Compressor
on Jul 9, 2009 at 12:30:22 am

Hi-

I'm using FCP 6.0.3 and Compressor 3.0.3. My task requires me to convert reference movies of AJa Kona DVCProHD 720p 59.94 material to Pro Res (HQ) 1280 X 720 and 24 fps. Most of the clips look fine. The issue is that some of the clips with movement start out with extreme strobing and then somehow instantaneously correct themselves about halfway through. I can see no noticeable difference in the source material to indicate what could be causing the problem and it's so weird that it happens in the middle of a shot. What's also weird is that it doesn't happen on every clip with motion.

Here's what I've tried...I switched from 24fps to 30fps and it seems to have solved the problem. Unfortunately, I have to stick to 24fps for my client. I also tried it on a newer version of compressor and had the same issue.

So, any ideas? Thanks a lot.

Quinn

I would use the following workflow for these kinds of retiming jobs:

DVCProHD @ 59.94 -> ProRes @ 29.97 -> ProRes @ 24 (or 23.98).

This may give you a more reliable result.
Let us know if you have already resolved this issue.

Thanks.
