CatDV won’t generate proxy file for ProRes 4444
I have some ProRes 4444 files rendered out from After Effects CS6. CatDV creates the MPEG-4 movie proxy(resize to no bigger than 640×480, H.264 video format) with proper sound but the video the black(I also tried other proxy formats). It only happens to ProRes 4444. Is it something to do with the alpha channel?
Does anyone have similar experience? -

I don’t have an answer, but I’ve seen tons of issues with 4444.
I’m assuming it’s a codec and that’s likely since there are tons of Apple updates out there.
Can you offer the OS your on etc? (Maybe also the ProRes codec version?)

I am running CatDV Pro 10.0.3 on Mac OS 10.8.4.
How do I find out the ProRes codec version?In the proxy setting, I’ve selected the size setting to “Scale do not exceed, 640×480”. Everything works except for ProRes 4444. But if I change this setting to “Single field(half height), then it works.
But I don’t wanna have half height because I have some old SD footage, half height is just too small. -
That looks like a bug in the ProRes codec that it won’t export to anything smaller than half its size. I can see the same thing when using QuickTime 7 Player Pro so it looks like it’s not specific to CatDV.
