Dear Stephane,
  The frame rates supported by the movie script depend entirely
on the back-end movie format that you choose to render to. At
present, the movie script only lists 24, 25, and 30 frames/sec
as choices, as these are the only legal values (well, ignoring
29.97 and NTSC drop frame etc) used by MPEG-I which is the main
video format I was initially aiming to support. Since AVI and
Quicktime allow a much wider range of frame rates, I do intend to
add many more options for those movie formats. I can provide you with
a modified movie script with additional frame rates if you tell
me what movie format you're generating, and what kind of computer
you're using, if the back-end movie maker can support it. Send me
a note with that info, and I'll give you a new version of the
script to try out.

For others reading this note, I do intend to make several improvements
to the movie maker script over the next few days to include more
user-configurable rendering and video encoding options, etc. This
will make the script much more flexible than it is at present.

Thanks,
  John Stone
