Green screen partial blown out for cloning audience
Hi,
I’m trying to fill the rows of a theater with the same 5 persons cloned in different positions, but on some scenes I have the problem of bad lighting such as in this case https://youtu.be/uZEP9EzWt-A (flat) / https://youtu.be/kKYOvgkoS1Y (rec709) where the persons on the sides are blown out by the light being so close.
I shot with the blackmagic production camera on 4k Apple prores 422. Considering the keying I’m planning on rotoscoping (the green background helps to use the roto brush tool in AE) but the problem is to even out the light on the actors to allow for a global color grade (avoiding the sensation that are spotlights over some seats on the audience). If I knew I would shot with just the green screen and no extra lighting, using only the ambient light but now it’s too late.
Any help will be much appreciated.
Thanks -

While I agree with Dave for the most part, I think in your case here you might be able to simply dupe you layer and work on the screen right side separately. Plenty of vids out there on how to go about doing that certainly. Goal at this point is to just get a a clean matte, but you might have to build it up from several layers or precomps. Once you have that, then color & light timing the subjects should be relatively easy.

Hi Dave,
Thanks for your always wise answer. Not all of my scenes are bad lighted, and fortunately some scenes that are on the first rows seats that are ok will hide partially the rows on the back, so i’m looking for a solution that could help to minimize the blown out areas. Considering that the total running time will be of 5 seconds and with all the clones moving, the important it’s not have pool of lights to not be noticeable by the viewers. Could you please give me a clue about the way I should take?
And it’s true, the error “will fix it in post” it’s the cavalry of the newbies.

Hi Mark,
Thanks for helping out. I´ve watched a lesson by Richard Harrington from Lynda.com course “repairing and enhancing video” about relighting a rotobrushed scene that is overexposed creating 2 lights, the first “ambient” dimming all the footage and a second light as “spot” adjusting in the case the light on the face of the subject, but I couldn’t get it right because I have the problem of blown out areas.
I’ve searched the youtube for a solution and besides the exception of a raw shooting (that was not my case) I didn’t find anything even considering davinci resolve. It seems that I have a big trouble on my hands.

If you need any directions with the rotobrush tool maybe this would help:

Hi Remus,
Thanks for your help. As a matter of fact the rotobrush was the way I choose and I get the result that you may see on this video: https://youtu.be/3RKWGONaYxQ
Still roto work to do, but my bigger problem now is to balance the light on the guys. I was thinking in perhaps export the video to photoshop, creating an adjustment layer and with the dodge and burn tools reduce the highlights. What do you think
