I just had a successful day of editing with iMovie, and things are looking great! I decided to keep things simple to start, and make my green screen clips all at once rather than splicing them into the segments I need and then do the green screen. That way, any color enhancements/size changes would be consistent across the videos. I also made two versions, one with me on the left side of the screen and one with me on the right to keep things interesting (thanks Dr. Weichmann and Francisco for this suggestion!).
I also experimented with the sound effects features. Since I didn’t want to worry about music licensing issues, I was unable to put my favorite bands in the credits, but I have a feeling viewers probably prefer that I don’t do that… Looking forward to putting the finishing touches on my last segment tomorrow!
