Updated the file!!

Just had a look at it. It is keyable, but definately not easily (the test I posted had JPEG artifacts that weren't in the original file, obviously)
The greenscreen is very uneven. Do you know if it was a real greenscreen ? It doesn't look very saturated, and the vertical lines are very visible on the background... Plus, the light isn't very even neither, and there is some vignetting in the 5K frame.
Also, there is quite a lot of noise in the vest, which is surprising given that the footage doesn't seem to be underexposed... Would love to hear from someone from Red...

Please try again, i reuploaded it!!

The subject is under-exposed. The green screen itself is poorly lit. But it's totally keyable as Nils shows. Personally, if it were my project, I would hand roto a garbage matte to isolate most of the screen from the subject and then just worry about keying the little bit around him not roto'd out. Combine both chromakey with lumakey layers. ...I've keyed far worse than this. Keylight in AE is OK, but kinda limited. Have access to other software/ tools?

I did give it a quick try
Quick and dirty key only one keyer and quick mask, it need more work but the footage can be keyed.
I used the Ultra-keyer in Fusion, in this case it solved the job better then primatte.

edit: clearly i didn't work on the spill, just tetsted wich keyer workes for you

The subject's skin seems contaminated with green, is there a way to fix it in redcine or something?
Like tweak some raw settings so it would give a better result?
Other tools could be used i think, any suggestions?

Thanks

its called spill light - there are lots of techniques - key light gets rid of spill quite easily but skin will become magenta as easy. you'd want to pick the spill and grade it away with whatever grading tool you have available - use the mask to isolate and then grade against the green.

Is there a way to tweak the raw file in redcine to ease the keying in AE?

This happens frequently when shooting in small insert stages, or placing the actor too close to the green screen. This is a good reason to use a much bigger stage, and get the actor at least 15-20' in front of the green screen background, to avoid spill issues.

After Effects, Nuke, Shake, Fusion... all of these are great examples of compositing software that have very good clean-up tools. But it always helps to have well-exposed, well-lit material to work with.

Using Andrew Kramer AE techniques this is rather basic to achieve excellent quality results.

Here's a similar situation in this tutorial.

Or you can hire me and I'll make it perfect for you.

Keying it is not a huge problem - but as others have pointed out, the green screen contamination in the flesh tones is more of a problem. This is keyed in Nuke...
