Best Colour practice when creating AI frames

I have a job where I would like to create a DMP using AI. The plate is ScLin - AWG. What’s the best process to get it into AI with half a chance of AI doing decent colour job for a return I can use? Do I have to turn it Rec709. Is there a trick that you all know of ? TIA as always.

I have had logC come back to me pretty successfully. Try making it log

Fought like crazy today with this and Wan in comfy doing head replacements. Exrs in LogC in and exrs or ProRes out—it didn’t matter there were always shifts. Some subtle, others batshit crazy.

The sampler could be fed the same sequence input with different start frames (to get around the frame limit) and come hell or high water the output was shifting wildly.

Going to try something else next time or investigate a little further into what’s going on under the hood. Just a heads up…

The most consistent workflow I’ve found is doing a milky rec709; creating a curve to lift the blacks and flatten highlights. I’ve had log work and not work. I did hear that linear exrs worked on something but haven’t investigated too much yet.

I have a few options to add:

sLog (Sony, the OG one) - This was used in 8bit cameras, and it looks the closest to rec709 of all the logs, but it’s still reversable in Flame.

In addition to John’s suggestion, the ‘Look’ node is reversable, so you can make your own hacky log to avid any nasty clipping, and then reverse it when you bring it back in.

For the colour shifts you get, I find Nuke’s ‘match grade’ node really helpful. Especially where you’re extending a plate into AI land… I guess AFX reverse grade might work in a pinch too.

After a bit of experimenting and fucking about I found a decent–not perfect–solution for maintaining some color conformity, in this case out of Wan but should work nicely on the output of other samplers.

Node is alled color match and basically you feed it your ref frame and then the output and it does its thing. Again not perfect but a decent step towards being correct. The image on the left is out of the sampler and the image on the right is within striking distance of the log ref frame and source sequence.

I was starting to play with that. @milanesa shared that on our Discord last week. Seems just like what we need.

Amazing! Can’t wait to try this!

Awesome… but only works with Flux for the time being. It’s like Photoshop finally becoming 32bit but having to process your motion on that still through a Hal.

Sigh.

Literally a joke for an audience of what, 5 people?

Did anyone grab this before it was taken down and care to share?

log 24fps should work pretty well

Ya mean dis @kyleobley

Amazing, thank you @randy.

Brilliant thanks @randy Would we just put that in our custom nodes bin? Sorry the instructions from the GitHub have disappeared

It’s where I got mine. :slight_smile:

I think all you have to do is check it in the custom notes bin in your comfy folder and maybe run the requirements file?
