-# Capture a continuous CMIF movie using the Indigo video library and board
-
-
-# Usage:
-#
-# makemovie [-r rate] [-w width] [moviefile]
-
-
-# Options:
-#
-# -r rate       : capture 1 out of every 'rate' frames (default 1)
-# -w width      : initial window width (default interactive placement)
-# -d		: drop fields if needed
-# -g bits	: greyscale (2, 4 or 8 bits)
-# -G            : 2-bit greyscale dithered
-# -m		: monochrome dithered
-# -M value	: monochrome tresholded with value
-# -f		: Capture fields (in stead of frames)
-# -n number     : Capture 'number' fields (default 60)
-# 
-# moviefile     : here goes the movie data (default film.video);
-#                 the format is documented in cmif-film.ms
-
-
-# User interface:
-#
-# Start the application.  Resize the window to the desired movie size.
-# Press the left mouse button to start recording, release it to end
-# recording.  You can record as many times as you wish, but each time
-# you overwrite the output file(s), so only the last recording is
-# kept.
-#
-# Press ESC or select the window manager Quit or Close window option
-# to quit.  If you quit before recording anything, the output file(s)
-# are not touched.

-# Usage:
-#
-# makemovie [-q queuesize] [-t recordtime] [-a] [moviefile [audiofile]]
-
-
-# Options:
-#
-# -q queuesize  : set the capture queue size (default and max 16)
-# -t recordtime : set the record time in seconds (default 5 seconds)
-# -a            : record audio as well
-# moviefile     : here goes the movie data (default film.video);
-#                 the format is documented in cmif-film.ms
-# audiofile     : with -a, here goes the audio data (default film.aiff);
-#                 audio data is recorded in AIFF format, using the
-#                 input sampling rate, source and volume set by the
-#                 audio panel, in mono, 8 bits/sample
-
-
-# User interface:
-#
-# Start the application.  Resize the window to the desired movie size.
-# Click the left mouse button to start recording (recording starts
-# when you release the mouse button).  Recording time is specified by
-# the -t option (XXX this should change).
-#
-# Press ESC or select the window manager Quit or Close window option
-# to quit.  (You can do this without recording -- then the output
-# files are untouched.)
-#
-# (It is possible to record more than once; but this doesn't set the
-# time stamps correctly yet, and doesn't work at all with audio.  So
-# don't use.)
-
-
-# XXX To do:
-#
-# fix timestamps for second and further recordings
-# fix audio      "   "      "   "       "
