the only complaint I have about the xl2 that can't be fixed with accessories is no real variable frame rates. on a film camera I run 36fps all the time, a pretty girl walks by and you just want the bounce in her hair to be a little romantic or whatever.

i've noticed that when working with 24p footage in final cut pro it is very obvious when you increase or decrease speed because all of the sudden it's converted to 60i and then goes back to 24p when it's done.

has anyone figured out a solution to this in post?

here's a couple of theories i've been meaning to try:

converting 30P to 24P, is there a way to sort of add a 3:2 pull down to 30p footage? Slowing it down to 80%, not enough but at least it's a VERY subtle change.

Shooting in 60i, using the 60i if i were to set the shutter speed to 100 that could possibly be slowed to roughly half speed but lose resolution and and remove every fifth frame. sort of like frame mode in a GL2 manually converted to 24fps

if shooting at 1/8 of a second will this convert to 600% speed nicely? using 1/8 of a second shutter speed and matching that movement to a standard 1/48 in 24p that would be a nice near time lapse effect and shooting 1/15 should convert to 320% and 1/24 should play back at 200%

anyone tried any of these?

This has nothing to do with the XL2 (since there is no DV camera
that has variable framerates in that manner), but more with
slowmotion in general, so I've moved this thread to our general
forum.

Also please do a search on this board on slow motion. There are
tons of threads on this subject and there have been a bunch
recently as well.

As you know 24p is the worst format to create slow motion for
(I don't think it does 24p->60i->24p as you claim). The best you
can do is shoot at 60i and then convert that to 24p.

The best shutter speed is a good question indeed and I have no
idea. I'd say it highly depends on your camera and the footage
you are shooting in combination with the angle etc. Experimentation
is probably best here.

There are also specialized programs to create slow motion, they
usually do a far better job (according to the users) than your
regular editing package. If I remember correctly twixtor was such
a program.
