Are there any good video editing apps for photographers?
I don't have any personal experience with video, but Neil van Niekirk, a photographer whose articles have thrown lots of light into my understanding of event photography, is using iMovie. Even though he wished for something more powerful 8 months ago, it seems to have remained his tool of choice so far. Armin Defiesta, formerly videographer, now mostly photographer, has written a comparison of iMovie vs Final Cut Pro X.

I suspect part of the learning pain comes from the fact that video processing tools are based on heritage of movie film processing, not evolved from photography tools. The terminology and primary controls therefore have been evolving independently.
