Vidding Exercises for Creative Distraction

I am pretty accustomed to dealing with different aspect ratios at this point, but I *hate* differing frame rates. Particularly because I often don't realise they're different until I render something, and then half the vid's gone all ghosty :( In this case the difference was 29.97 fps vs 30 fps, so I could easily make the one run at the other rate, but it's still a pain.
