Hello, I'm using Resolve 18 to key some Canon Raw green screen footage. Everything goes relatively smoothly until I adjust the Matte threshold. The Alpha channel looks pure white, but the footage gets black splotchy / grainy. I can't find any work arounds to get rid of this. I believe my footage is exposed well. I tried a quick Colorspace transforms (guessing settings) in my node tree to see if more saturated footage would help, but it did not. I tried as many different workflow attempts as I could find. I used a clean plate as the keyer color, and the footage still gets the black dots. When changing view mode to intermediate result it did seem to get rid of the black dots but the green background came back at half transparency, so I assumed it wasn't working? I also tried the 3d Keyer and got a nice result with no grain, but the mask had a green outline. Is this a better keyer than the delta?

Hi all, Just wondering what is the proper way of going about this, I shot some video of talent on green screen in 4k Raw. Now that it is time to pass off the footage to a third party for compositing, should I give it a color grade and export it out at a high ProRes codec, or would I pass along the raw footage? Is it easier to key Raw footage instead of footage that is graded? Just looking for some professional tips, I am asking the third party their preferred method as well! Thanks!

Hello to all, I need to shoot an LED TV, the content will be added in post production so it needs to be a clean Green for keying, however I did some tests and the Moire Patterns that appear are unbearable. Im shooting on the Red Dragon so it is not a compression issue. Any recommendations on how to deal with the problem? The patterns disappear the second it's slightly soft, but I rather keeping the television in focus. Thanks! J.
