Selective green screen (Vegas Pro 14)
Hi there,
I have two videos I’m working with–Clip A and clip B. I want to place clip B over only a small part of clip A, which has a small green screen spot. I have only touched green screens when it comes to photo editing, so I am very in the dark when it comes to video editing.
I’m using Vegas Pro 14, and I know the “chroma keyer” function would be the route to follow, but would anyone know how to put clip A on top of only a small selection of clip B? I haven’t been able to find much of an explanation past “chroma keying” them.
Here is a picture for reference:

One big issue, I know, is the lighting. It may not be salvageable (my cameraman believes everything can be done perfectly in post with little lighting), but if it is, any advice would be wonderful!

Hi Jasper,
If I understand you correctly, you want the hand (with a green screen background) over the other clip. Put the hand on the top track with the background under it on the 2nd track. In the clip with the hand, us the Chroma Keyer Fx to select the green color and play with the in/out thresholds until the green is clear and showing track 2. If there are parts of the hand clip which do not have the green background, use a mask in Pan & crop to crop that portion out of the hand clip.
And yes most likely you will need to light the green screen much better, despite what your camera thinks.
Best Regards……George

George, I’m no green screen expert but I think this will take three tracks as follows:
Track One .. Image of Hand on Green screen area.
Track One .. Pan/Crop mask of green screen area with Negative Mode applied.
Track One .. Chroma Keyer FX applied to knock out mask. Green area should go black and the rest of the frame should reveal the image on Track Two underneath.Track Two .. Image of Hand on Green Screen area.
Track Two .. Chroma Keyer FX applied to fill green screen area. Green area should reveal background underneath on Track three.Track Three .. Background image that will fill green screen area.

Paul, yes I agree that would be the workflow for his current project, I was stating how I would have done it from the start. Thank You for your post, as I might have added confusion to his workflow.
Best Regards……George

George, I didn’t mean to say your suggestion would not work if one had a decent green screen. I think it would, right?
But in this case, with the image the OP provided, I could only get a passable result with three tracks.

Thank you for your post! I’ve learned significantly more from these posts than I had while searching for a couple days! I understood both of the posts and definitely appreciate the assistance!

This is wonderful, thank you! And that you even gave an image of it working! I know the lighting is sub-par, but it’s good to see it is do-able! Thank you very much!
