Green Screen Problem


#1

Hi there. I am new to Natron. It’s a very powerful software. Thanks for the developers.

When I add two videos (one is background and other one is green screen) and key them, it is ok. But when I scale the green screen video via transform node, background video looks black. Why? Are there any alpha options in Natron. Thank you.

Not sure if this will help you or not with your issue, but give it a go. https://youtu.be/2cbABfUDqhw

I show another technique here, where you use the mask input of the merge. In this video, you could substitute your keying for the black and white matte I make. Just set your keyer to output the matte then run it into the mask of a merge.

Thank you for the answers. I’ll have a look at them.
