I'm a brand new Mac owner and I'm brand new to editing digital video. I have the latest version of FCE. I have put a chroma keyer effect onto a clip in my sequence. When I play THAT clip, the audio is not in sync with the video. In any clip that I haven't added the chroma keyer effect, the audio is still in sync. Is this something I need to FIX or will it be fixed when the footage is rendered? In my other video that I did the green screen effect on (in the same manner) I had no problem with the audio not being in sync. Thanks!
