NAME    [Toc]    [Back]

     makemovie - make a	movie from movie, image, and audio files

SYNOPSIS    [Toc]    [Back]

     makemovie [-o outfile] [-f	format]	[-c compression] [-l loopmode]
     [-r framerate] [-i	interlacing] [-t] [-s xsize,ysize] [-b]
     [-q spatial_quality] [-p temporal_quality]	[-a bitrate]
     [-k keyframe_rate]	[ file1	... ]

     makemovie -D file

DESCRIPTION    [Toc]    [Back]

     makemovie is used to take image and audio data in a variety of forms and
     put them into a movie file	that can be edited with	moviemaker or viewed
     with movieplayer.

     The -o option must	be used	to specify the file in which the resulting
     movie will	be placed.  Image and audio data are taken from	the input
     files in the order	listed;	this ordering determines the order in which
     they will appear when the movie is	played.	 The options -c, -l, -i, -t,
     -r, -s, -b, -q, -p, -k, and -a can	be used	to set the compression scheme,
     loop mode,	interlacing, orientation, frame	rate, image size, image
     blurring, spatial quality,	temporal quality, keyframe rate, and bitrate
     of	the output movie (see below).

     The input files may be images, audio, QuickTime movies, SGI movies, or
     MPEG-1 movies.  Image file	formats	are those supported by the IRIS
     ImageVision Library, which	include	ilSGI, ilFIT, and ilTIFF. Audio	file
     formats include AIFF and AIFFC.  makemovie	can read QuickTime movies that
     have been compressed using	"Animation", "Video", "Compact Video", "jpeg",
     or	no compression.

     For editing operations, it	may be preferable to generate the movie	in
     uncompressed format, then compress	it afterward. This is because most
     compression schemes are slightly lossy, and some image degradation	may
     result from long decompression-compression	sequences. However, this will
     result in increased disk space requirements, since	uncompressed movies
     are much larger than compressed movies. Typically,	for "real world" video
     data, the compression achieved is about 8 or 10 to	1, but with simpler
     data, such	as many	computer graphics images, the compression achieved may
     be	much greater, possibly 20 to 1 or so disk space	should be planned

OPTIONS    [Toc]    [Back]

     -f	format
	  Sets the file	format of the output movie.  Choices are "sgi" for the
	  SGI movie format and "qt" for	the QuickTime movie format.

     -c	compression
	  Sets the compression scheme for the output movie.  Choices for the
	  SGI movie format are "none" (no compression),	"mvc1" (an SGI video
	  compression scheme), "mvc2" (another SGI video compression scheme,

									Page 1

	  with slower but greater compression and faster decompression than
	  mvc1), "jpeg"	(standard JPEG compression), "rle" (8-bit run-length
	  encoding), and "rle24" (24-bit run-length encoding).	Choices	for
	  the QuickTime	movie format are "qt_anim" (QuickTime Animation),
	  "qt_video" (QuickTime	Video),	"qt_cvid" (Compact Video), "jpeg", and

     -D	file
	  Describes the	contents of a movie file.  Cannot be used with any
	  other	options.

     -l	loopmode
	  Sets default looping mode for	playing	the movie.  Choices are:
	  "once" (play the movie once),	"loop" (keep playing it	over and
	  over), and "swing" (play it front-to-back, back-to-front over	and

     -r	framerate
	  Sets the rate	at which the images in the movie will be displayed
	  during playback.  This option	can only be used when making movies
	  from image files.  If	any of the input files are movies, they	must
	  all have the same rate and the output	movie will be given that same
	  rate.	 The default value is 15 frames	per second.

     -i	interlacing
	  Sets the interlacing of the image track in the output	movie.
	  Choices are:	"even" for PAL (even lines first), "odd" for NTSC (odd
	  lines	first) and "none" (no interlacing).  Images are	non-interlaced
	  by default.

     -q	spatial_quality
	  Sets the spatial quality of the image	track in the output movie.
	  This is useful for setting the quality factor	of a JPEG compressed
	  image	track and for setting the spatial quality of QuickTime
	  Animation and	Video tracks.  spatial_quality must be a floating
	  point	number between 0 and 1.0.  The default value of	the spatial
	  quality varies with the compression scheme.

     -p	temporal_quality
	  Sets the temporal quality of the image track in the output movie.
	  This is useful for setting the temporal quality of QuickTime
	  Animation and	Video tracks.  temporal_quality	must be	a floating
	  point	number between 0 and 1.0.  The default value of	the temporal
	  compression varies with the compression scheme.

     -a	bitrate
	  Sets the bitrate for those compression algorithms that allow you to
	  specify a compressed bitrate.	 bitrate is specified in bits/second
	  and must be a	an integer greater than	0.

     -k	keyframe_rate
	  Sets the frequency at	which keyframes	occur for those	compression
	  algorithms that use keyframes.  keyframe_rate	must be	an integer
	  greater than 0.  The default value of	the keyframe rate is 5.

     -t	  Sets the image orientation of	the output movie to be top-to-bottom.
	  The default orientation is bottom-to-top.

     -s	xsize,ysize
	  Sets the frame size of the movie to be created. This option
	  overrides the	default	frame size, which is the size taken from the
	  first	image or movie file listed.  If	any of the images are the
	  wrong	size, they will	be adjusted to fit by letterboxing.  This
	  means	that they will made as big as possible within the new size.
	  If the aspect	ration of the new size is different, there will	be
	  black	borders	either at the top and bottom or	at the left and	right
	  of the images.

     -b	  Blurs	the image track	of the output movie with a 1-2-1 vertical
	  convolution filter.  This reduces flicker if the movie is played
	  back through video.

     -o	outfile
	  This option is required and names the	file that will be produced.

EXAMPLES    [Toc]    [Back]

     To	make a compressed movie, movie1.mv, from audio file afile.AF and image
     file img.fit:

	  makemovie -o movie1.mv img.fit afile.AF

     To	make an	uncompressed movie that	will play at 10	frames per second from
     audio file	afile.AF and image files img1.FIT, img2.FIT, and img3.FIT:

	  makemovie -o movie2.mv -c none -r 15 \
		    img1.FIT img2.FIT img3.FIT afile.AF

     To	make an	odd interlaced,	640x480, JPEG compressed movie with top-tobottom
 orientation	(of the	sort that can be played	back on	the Cosmo
     compression board using NTSC timing) from image files img1.rgb, img2.rgb,
     and img3.rgb:

	  makemovie -o movie3.mv -c jpeg -s 640,480 -i odd -t \
		    img1.rgb img2.rgb img3.rgb

     To	do the same thing for PAL video:

	  makemovie -o movie3.mv -c jpeg -s 768,576 -i even -t \
		    img1.rgb img2.rgb img3.rgb

     To	make a top-to-bottom QuickTime movie compressed	with Compact Video and
     with a spatial quality factor of .5 from image files img1.rgb, img2.rgb,
     and img3.rgb:

	  makemovie -o movie4.mv -t -f qt -c qt_cvid -q	.5 img1.rgb \
		    img2.rgb img3.rgb

     To	convert	a QuickTime movie (monkey.qt) to an SGI	movie (monkey.mv):

	  makemovie -o monkey.mv monkey.qt
