Keying Out Non-Green Screen Footage
I have to key out an actor against a grey set with a gradient tone. For the most part, the set is almost white, then toward the bottom, it becomes dark and there’s a floor.
By looking, I thought the actor was already keyed as a sample! So in prepping for this (as I don’t key often — once a year maybe), I only studied tutorials on keying against green. Now I’m in a panic.
My Software Tools:
AE CS4 with Keylight
Red Giant Primatte Keyer Pro
Red Giant Key Correct ProPlease direct me 🙂

Mr. LaRonde,
I am trying to find some RAW footage from a Red camera. I was reading some forums and keep coming across your name. Is there any way you could put me in touch with a 15 minute section of RAW footage? We are a storage provider working with a client and need to do some testing and that will be the type of cameras that are to be used but are not acquired yet.
I do not want to alter the footage in any way, just store it using our solution and then provide it back in the same format.
Thank you for any help you can give me!

Here’s the footage
You just confirmed that it’s not just me. They are aware of the production error, so I’ll do my best.
I think that Red Giant’s Primatte Keyer Pro tool will serve me best because it allows the precise selection of a range of colors. So where the colors vary, I’ll re-sample until all of the gradient has dissolved….I guess!

Thanks, but I’m using a Mac Pro and MBP. The footage should be HDV, but I’ll confirm.
I can’t install anything on the company’s computer, but I think I have all that I need on my own equipment.

This might just do the trick…
It’s a tutorial for sky replacement — but the principles are the same for your conundrum…
hope it helps…https://www.videocopilot.net/tutorials/advanced_sky_replacement/

I don’t think a normal keyer will work, but Primatte with plug holes set really high worked good. Almost everything on a person is grey…try my saturation project. turn off the blur and see if you can get a good track matte from it. Also, another option, autotrace will keep groups of color selected.
