I can see the "sense" of it, too; nevertheless, it strikes me as a rather contrived justification for it. There aren't very many videos that don't involve motion. As a side note, someday camera sensors will probably become more light sensitive (but I haven't read of anything specific yet). As for the question in the last paragraph, the question isn't 100% relevant given that PPro works on frames, one after the other, independent of the playback frame rate. Even though 24fps uses fewer frames than 30fps causing it to appear to process a timeline faster, that would only be an illusion because PPro (and associated hardware) process the same number of timeline-frames per second regardless of the intended playback rate. However, stuttering preview playback of 24fps material will be slightly postponed because the computer has more time to process each frame, so PPro previews might seems more robust, but again, the processor itself runs at the same speed.

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?
