Just as "lol" is NOT punctuation *, EDITING YOUR FOOTAGE AT 24 fps WILL NOT MAKE IT LOOK LIKE FRICKIN' FILM!!!
If you shot it in 50i or 60i DEAL WITH THE FACT THAT YOU'RE SHOOTING ON VIDEO!!!!!
Play with the levels, the contrast, the chroma saturation, the Gamma curve, the interlacing, whatever, but just changing your footage so it cuts out frames is only wrecking what you shot, not creating some sort of quick-fix aesthetic alternative.
Ahem. Sorry. I'll go back to what I was doing now. Where's that can of Coke? I don't feel like I have enough caffeine in my system yet.
* Thanks to Patrick for that one.
