Question

Changing RAW color temperature over time

I'm hoping someone has a trick for this. I've been shooting sequences of RAW images from Sony cameras into AE using the Camera RAW 15.0 tools to process the shots before adding as footage. That's gone very well, but a number of my sequences start in the afternoon and go well into the evening, so there's a significant shift in the color temperature of the skies and city lights of maybe 1000K and 10pts of tint from the beginning to end. 

 

Has anyone figured out a way to have sequences interpreted like this from RAW update specific settings (like color temperature) between keyframes? I have a feeling it's one-stop shopping with the interpretation... 

 

Thanks for any ideas!

If you have to shift color temperature, use Lumetri and set keyframes or add two copies of Lumetri, add a Mask for each copy of Lumetri and then animate the mask opacity with Mask 1 set as the compositing option for Lumetry 1 and Mask 2 set for Lumetri 2. I use masks for compositing options with Effects all the time. 

 

As long as the Comp is 16-bit or better, you won't lose anything, and Lumetri has great color correction tools. Much better than Tint.

That would be a terrible workflow even if it were possible. You don't mess with this stuff. The settings don't work linearly and affect other parameters, so this would be a nightmare. Instead duplicate the sequences and apply different settings, then blend them by animating opacity or other parameters in the colro correction like exposure or of course the various selective corrections.

I kind of figured it wouldn't be easy, and my workaround has been to make subtle corrections using HSL settings after import. These sequences are from 10K sequences, shot then rendered as ProRes4444 masters for further use outside AE; so a perfect world solution would be to correct color temperature on import, then leave everything else for post. Worth asking though. Thanks!
