24/29.97/30 frame rate conversions



Could someone please point me to descriptions of frame rate conversion
practices
for moving from video to film and vice versa.  In particular, I'm interested
in when/where the .01% slow down/speed ups are introduced and what is
normally done with audio (e.g., sampling at 48048 and playing at 48000).
And, if there are any "standards" for which frames to drop when turning
30fps material into 29.97 fps material.  (I know of the dropframe timecode
standard... but I didn't think that would necessarily apply here).

Much thanks,


Eric Bloch
