Keying back a colour – I’m sure I’m being dumb but…
I want to key a colour back from my source to the end of a node tree.
i.e. – say I build a fairly heavy “look” with a few or more nodes, and I then want to key back blues from the original (or base corrected) image. I create a node in free space, connect it to the source node (before all the heavy corrections) but then I can’t seem to work out how or where to connect the key and rgb signals in order to key the blue back in at the end of the signal chain….

Try using a layer mixer.

Thanks Rohit. But the layer mixer has only rgb inputs doesn’t it? Where does the key signal go?
I sometimes use the parallel mixer, but it is hard to tell how it combines the signals.

The layer mixer uses the qualification on each input node as its key for that node. Unlike the parallel node, the order of inputs determines the priority.

Thanks, I managed to get it to work as I want. I don’t really get it because I thought the key channel would need to go somewhere but happy to get the result!
