I'll be renting the DVX-100.

My movie is about a kid who wants to dunk a basketball.

the last attempt he goes for it, looks like he is about to make it and freeze frame...

but in real life my actor is 5'4 and probably can't come close to that...

what is the best way to get that shot... i know I can do closeups...

but it would be cool to do a wideshot and it looks like he is almost there.... almost make him look like michael jordan in mid air....

I guess you could use blue screen or something, but I don't want to do that. I want to do in live somehow.

Any ideas?

Also since it's slow mo, I heard 30 p will be easier to slow down than 24 p. Is that true?

Pretty simple: either lower the hoop if possible, or raise the player. You can use a spring board like the type used in gymnastics so the player can get more air, or build up a platform below frame to minimize the height difference. If you use the springboard, make sure to do plenty of test runs and ABSOLUTELY use lots of padding around the base of the basket. Mattresses (air mattresses even) will do in a pinch.

BE SAFE!!!
