mask and chromakey

[LakeCity]

Hello everyone!

So: I've got a few video's with a white or black background. I'd like to delete the background of the video's, so the background is transparent and the underlaying layer is also visible.
I know I can use a image file as a mask, but that doens't work for me because the part I'd not like to be transparent is moving. (I hope you can understand what I mean...excuse me for my english)
I also know I can probably use chromakey for this, but everytime I try to use that effect, resolume crashes for some reason,
I can delete the background with other software ofcourse, but that will cost me a lot of time.

I'd like to know why the chromakey effect crashes, and if there's an other way to make my idea possible!

Thanks in advance!

You can remove black very easily with the AutoMask effect. Removing white can be a bit trickier, but I've gotten decent results by using Invert RGB first, then automasking and inverting back again.

The reason ChromaKey crashes it most likely because you don't have a dedicated GPU.

Damn, I never saw that effect...guess I always looked past it.

Well, at least I know now and it works just the way I want it.

Thanks a lot
