    Hi, all. I finished green screening a character using the rotobrush, rendered it, and implemented it into one of my recordings (putting the character irl). When I went to keylight the green screen background, the character becomes transparent and the character has bits of green so those were removed as well. I tried to work around that by changing the color of the bg and changing “final result” to “intermediate result” to retain the original subject’s colors which helped but then there’s still the matter of transparency that shows the track behind it.

    Disclaimer: I am a complete, utter novice at using any software ever so please, give simple explanations. I’m sorry

    Getting a good key is an art form in itself. Did you know there’s a preset for keying? Search for “keylight + ” and this gets pretty good results. If you’re getting semi-transparent images, you’ll probably need to change the keylight view settings to screen matte, and then use a levels effect to strengthen the whites and blacks. Then you can use this layer as a luma matte for a duplicate of your footage without any effects.

    If that all sounds too complicated, I think this video is a pretty good starter: https://www.youtube.com/watch?v=4kfFggpdpis
