Chroma-Keying in Adobe Premiere
When used appropriately, chroma-keying can be used to bring a really cool effect to your movies. Unfortunately, I won’t be able to provide pictures this week as my computer is on the fritz, but I can attempt to give you enough information to get you started.
First, layer your video tracks. Premiere will prioritize V1 and then V2 and so on. Therefore, you want your foreground track to be on V1 and background on V2. From there, let’s go into the “Effects” menu and look for “Chroma Key”.
Still with me? Good. From here, you should (ideally) have the foreground video you want to key out in your timeline viewer (the one on the right) and the Chroma-Key effect panel on the left viewer (I’m assuming the default Premiere layout). From there, look for the “Key Color” attribute and click it. You should get something resembling an eyedropper. With that, go over to your Timeline viewer and click on the color you want to key out. It should (partially) disappear to reveal the background video track.
To smooth it out a bit, give your “Tolerance” and “Feather” effects a few tweaks. Tolerance modifies the color range that Premiere will key out, and Feather will blur the edges of the key so as not to make it too harsh. Have fun playing around with Chroma-Key!
