Compositing Greenscreen footage with "challenges"
 

i'm working on a project where i have two people in front of a greenscreen. the problem is, these two people have a green and yellow logo in their hats. they were told not to wear any green, etc. i'm not sure why they did it anyway, but i'm just getting the footage and they want to know what i can do to make it work anyway.....any ideas? what is the best way to solve this issue?

oh, they're unable to reshoot the footage due to everyone being in different states, countries, etc.

Fairly static, or a lot of movement and how close are the two greens....? Post a frame grab at least..

for the most part they are looking straight ahead and occasionally turn their head to the left or right where you can see green words on the helmet. here's two screenshots. one is when they are looking srt8 ahead and the other is when they turn their head.

A garbage mask should help you out. One more layer, one more step, more render time but that doesn't look too bad.

Edit: just saw the printing on the side. THAT may be a little harder.

Unless the subjects in the video are going to be moving around wildly you should be able to do as Shaun suggested with good results.

Looks like the logos are an essential part of the final product? Especially if that's the logo of the client.

You could try tracking the entire helmet, then attach a rotomask to that tracker. Make manual adjustments where the rotomask strays from the proper position.

Or just rotomask the offending area and track by hand with keyframes. This one shouldn't be too hard.

I had to do a bunch of rotomasks for a commercial spot. One shot involved a woman and two kids running toward their SUV. It included a girl's ponytail and constantly changing shapes. Took five hours to rotoscope a clip that ran for less than four seconds.
