If your shooting on film or were shooting on film, its always best to get the camera assitant to expose a few frames with the ground glass markings to get the aspect ratios in place to figure out how excatly the DP framed his shots.

It almost always helps for short films like we always do.

Hi
Sorry to say but there is no "inbetween" ratio. I highly suggest shooting in 16/9 and then pan & scan if needed to package - but I doubt it. We are all going into the HD world and 4/3 will die eventually. Even for specific festivals, offer a 1,78, as offered in HD and DVD. This will proove you're modern and aware of the new standars. Do not limit yourself in a 4/3 frame in your action, it's not worth it anymore.

24p?

Actually, there is an accepted "in-between," and I'd suggest at least trying it. 1.66:1 is narrower than 16x9 and wider than 4x3, and it's been used all over the place, including Dr. Strangelove. It's not as widely used anymore, but take a shot and see how it looks.

I myself usually use 4:3 or something wider than 16x9 because I think 16x9 is ugly ugly UGLY.

But that's just me.
