I am using Photoshop CC 2014. I currently have 2 layers, one a video which is a smart object and has a chroma key background. The other one is a blank layer (see below). I am trying to create and outline of everything except the chroma key and put it on the second layer. This need to happen on every frame. I have been just tracing it, but this takes a long time, does anyone know how to do this quickly?
If you have access to Premiere Pro/After effects do it there. They are set up for chroma key.
If you must use Photoshop then you could speed up the selection with Select Color Range or as an alternative look at the blending options for the original video layer and see if Blend If > Green will do the trick
Thanks. This worked but is a bit fiddly.
