I'm new to FCE and I am incredibly confused. When I try to use the "chroma keyer" effect, it doesn't work. Nothing changes in the canvas when I use it. The effect shows up on the "video" tab of the viewer window if I click "view match frame" on the bottom of the canvas window. However, the effect doesn't hold for anything else. From what I've seen on tutorials and such, the effect is supposed to be in real-time with the canvas, and affect the sequence itself on the timeline. Is this simply something that I may have accidentally clicked that isn't allowing this to happen! Help! Thank you!
