Remove green screen from green object

Hello Premiere Pro experts,

I filmed a 26 minute video yesterday in front of a green screen, and didn't realize my guest was wearing a hat, in which half of it was green (the exact color of the green screen.)

I went to apply the ultra key to the video in Premiere Pro, and the green of the hat became transparent.

What is my best method to fix this? Mind you the video is 25 minutes long, and his head moves throughout the video.

Can I fix this without spending significant and tedious time? Is there a Premiere Pro tool that I can apply which would recognize the shape I define over his hat, and remove the green screen while adjusting and applying automatically to each frame movement for the entirety of the video?

If there isn't a tool in Premiere Pro for this, is Adobe planning on making one? There are many people who run into this issue, because you can't always control the attire color of guests.

Thank you very much

You can use the Change Color effect. See my 30-second tutorial:

I can't speak for Adobe but I would be very sure they won't be planning on creating a solution for this as it's the nature of colour keying. Whether it's green, blue or sodium vapour yellow (used in the mid 20th century in films like Mary Poppins), or even ultra violet light keying - any matching colour to the background key colour will be lost as well.

I remember there was a 'hole filling' plugin for After Effects - forget what it was called or even if it still exists - but these are only really designed to fill minor 'alpha holes' not automatically create an edge to (in your case) the sides of a hat.

As the previous posters have pointed out this is best 'fixed' using masks in After Effects. It would be possible to create a duplicate layer of your 'hat guy' on v2 in Premiere Pro and then manually mask his hat back in to the keyed layer but you'd have to manually animate the mask over the full 25 minutes ... and this would be very painful.

Masks in After Effects are much easier to create and manipulate and you can even 'track' the footage and partially automate this process. Mocha AE would be even better.

Good Luck.

I would use Mocha AE in After Effects, motion track the hat/head movement and apply a mask over the green part. This will take some time setting up the mask and making sure it tracks properly for a 26 minute video but this would definitely get around your issue.

I will try this out. Thank you for your reply.

That might need a painful rotoscoping in After Effects.

You might want to also ask on the AE forum.

Hi Peru,

Does Premiere Pro not have a fill holes feature, where I can define the hole parameters?

Thank you for your reply.

There is a masking feature, but I think it might be difficult to do well and might take as much or more work than rotoscoping to achieve good results.
