Color shift when rendering to DVCPRO50
First project in AE CS3 and I’m having trouble when I render out using DVCPRO50. The rendered file has a color shift that occurs after a couple seconds. the shift occurs in a different spot every time I rerender. It does not appear in preview. its not an errant keyframe or the like, as I it happens on multiple projects. The footage is DVCPROHD, but I am downrezzing. FCP 5.1.4, KonaLHe.
I’m on a deadline and any workaround would be brilliant. -

Can you use another app to convert the footage to, say, uncompressed 8-bit, before importing into AE?
-
yes. are you implying that the trouble lies in the DVCPROHD nature of the footage?
-
I’ve noticed some strange RAM preview behaviour with DVCPROHD footage. Occasionally, frames appeared with slightly raised brightness and lowered contrast, but the renders were fine. Just to be sure, I converted the footage to 8-bit uncompressed for now.
Your situation may be related.

Once I have some time, I’ll do some testing.

i have exactly the opposite problem, all my previews are great, but my renders all shift. all of them. I definitely think it is DVCPRO HD related.

I like my problem better, sadly.
Can you save a RAM preview?
Have you tried rendering to a different codec? -
can I save a RAM preview? I don’t know. Your heads on the Cow AE wall-of-fame, you tell me.

Guess I’d better earn my headness, then: Composition>Save RAM preview.

Here’s our solution. We export from a FCP DVCPro50 timeline to a DVCPro50 clip. Import that into AE CS3. First thing is to go to your AE File menu and at the very bottom go to the Project Settings. In there under Working Space select SMTPE-C way at the bottom of the list.
Now select the clips in your AE project that are DVCPro50 and go to the interpret footage menu. Under the Color Management tab go to the Assign Profile and once again, choose the SMTPE-C setting.
Now, when you render it out to DVCPro50 you will see that in the render setting under Color Management the color space is already set to SMTPE-C.
When we do this our rendered clips are an exact digital match to the clips in FCP. We finally have a workflow with DVCPro50 that will match going in and out of AE.
Try it and see if it works for you!
