Crok Chromawarp with alpha media


I have a client looking to use Crok Chromawarp (or similar) on a GFX overlay supplied by a gfx company. The idea is to affect the overlay GFX, but not the footage underneath. When I try to apply this in a batch, the alpha stops working, can anyone help me with a workaround for this please?

Thanks in advance!

Hi Eddie. I believe I’ve seen this too, a bug in the user Matchbox. My workaround is to duplicate the node being fed the front, and input the matte instead. You can mimic-link the two nodes so they’ll have the same changes you make.


This worked a treat, thank you!
