I am new to green screen. My question is if I have green screen clips on my timeline in Premiere do I dynamic link to After Effects do Keylight and keep editing in Premiere? I was under the impression I had to save the green screen separte as transparrent file and import it into my project?
While Premiere can do keying, it's far superior in After Effects. Just right click to bring the clip into after effects, do your keying in there and then just save. Dynamic Link will make everything work nicely.
