Tips on keying green screen footage.
Hey everyone.
I got this footage from a client…I just need to key out the green and add a simple white background with a vignette.
I have been using the “inside and outside” technique of focusing on the inside and then duplicating and focusing on the outside.
I seem to keep losing some of the hand and the finger nails regardless.
Any tips on getting the perfect key for this?
Thanks!

If you’re going to be working with this client any more please advise them to consult with you on best practices for lighting and shooting green screen footage prior to future work. This footage is going to haunt my nightmares and I’m not even the one that has to deal with it!

And the kicker is that it will be composited over white… Why not just shoot it over white and bypass keying…
Not that this will help you here, but like Darby said, if you work with them in the future, there are 3 glaring issues with this shot.
First would be if you are going to key green, you want to avoid using green on the subject… Green nail polish was a poor decision and could have easily been avoided.
Second, the white balance is all screwed up… They most likely balanced off the LCD screen, which is much more blue than the studio lights they used. The LCD is probably pretty close to daylight color, between 65k-93k kelvin. They lights look like they were tungsten, so around 35k kelvin. This not only makes the skin tones orange, but the green screen isn’t green anymore, so it will be really tough to get a good key. All they needed to do was add blue gels to the lights. They are called ctb gels (color temperature blue gels) and are a standard in lighting for film and video.
Third, the green screen should be lit a lot more evenly than that. Their camera probably has zebra bars meter that can easily display issues with lighting evenness.
Vishesh’s suggestion should help, but you may need to resort to rotobrushing for some areas. The clip is short, so it really may be the fastest way to get it done.

Ha ha. Green fingernails on a green chroma key screen. Your client aint to bright.
I did pull a nice key using Keylight, but the nails were red. Hours of rotoscoping with Mocha or Rotobrush might work, but I wouldnt wish that on my worst enemy.
Sorry you have to deal with this silliness 🙁
