I was wondering,... can We use the word "Avid" in a plugin or other part
of the software?
Avid is a trademark.

It probably could have been named ChromakeySpectramatte which is too long. But naming it ChromakeyAvid as one word should be OK? I do not know for sure. Alternatively, we can just replace ChromakeyHSV with ChromakeyAvid which then breaks old projects AND new projects who started to use it as ChromkeyAvid.

quote from the internet: Spectramatte is a fairly decent keyer but is showing it's age, as Avid haven't really updated it since it was introduced over a decade ago.
