I have since read on the web that a slower frame rate is better for low-light situations (you can get more light in per frame) and faster is better for quickly moving subjects and pans (there's less blur and trailing). That makes sense.
Interlace also improves motion capture, but each frame has two slightly different fields so you can get combing. I also found out that the Canon pf24 frame rate uses pull-down to fit its 24 frames into a 60i-recorded file, not an optimal solution. I guess I need to compare frame rates in low-light and motion situations and look closely. Does anyone know if Premiere Pro 5.5 handles some frame rates better than others?
