AE render won’t match

[Rafael Amador]

Hi Ron,
You are doing nothing wrong. i’m afraid this have not solution. AE renders in RGB whatever the codec you use on exporting. It will always be a kind of shift in color/bright respect to the YCbCr footage. If you can do it in FC this shift won’t happens.

Sorry news for you. But…

Render out the whole interview clip, fix what you need and bring the whole thing back in.

At least then you won’t have the shift…

You might also try redoing the After Effects fix in Motion. I can’t guarantee that it’ll work, but you never know.

Wow, what a bummer.

Well, thanks for the information. At least I know it isn’t operator error (as usual).

And to think of all the versions of After Effects I have purchased and used through the years…and the fact that I just upgraded to the newest version with expectations that it would play nicely with my new High Def studio! Real bummer!

Since everybody but me (until now) seems to know about this, do you know if Adobe is doing anything to address this problem or is it so ingrained in the AE way of doing things that a fix won’t appear?

Are there any render settings in AE or Color adjustments in FCP that are shown to ameliorate this? Otherwise, I guess I’m going to have to learn Motion a lot better — and hope it has the capabilities that I need.

Bummer!

I’ve just done a bunch of work in AE with DV-50 and uncompressed codecs in SD and not a single pixel drifted in color or gamma! What’s up with ProRes??

Aaron,

I don’t believe the posters above were saying that this is a ProRes issue. I take it that it is a more general colorspace issue.

Are you saying, Aaron, that you have been able to accomplish successfully what I have so far failed to do, as described in my initial post, above? If so, I would really appreciate you passing along the workflow/settings that you used.

Cheers,

Ron

Nothing to fix in AE (why AE, Shake, Combustion etc do not render in YCrCb?).
Is not a problem of the codecs but of the color space. You will get similar color/bright shift rendering inside FC in RGB.
This article of Poynton gives the clue:

In AE, go to File-Project Settings and in the Color Settings select in the pulldown either HDTV or SMTP-C. We have successfully taken DVCPro50 and DVCProHD from FCP and back with no shift doing this. You will also have to choose your footage and match the setting you chose in the project settings for color. Click on a footage clip in the project window and hit Command-F (Control-F on a PC) and in the second tab you will see a setting at the bottom with your color settings. By matching this to your project setting, and a little trial and error, you should be able to take clips back and forth with no shifting.

Try it and post back. Has been working for us, even though other posters have not been successful. It took a couple tries, but we got it to work.

Best way is just to render out a clip from a comp without doing any effects and put it back in FCP and compare it to the original…

Thanks! I’ll give it a try and post back.

Rich has got it right. Check out those colorspace tabs…. Even though we’re all dealing with YUV to RGB and back again, the resulting renders should be virtually indistinguishable from the original footage.

When I get in the office tomorrow, I’ll look at my AE settings. I actually haven’t been bothering with the colorspace preferences working in standard def – AE’s initial settings have worked perfectly well. Are you on Leopard by chance?
