The FLI/FLC Animation Format
The FLI/FLC animation format, originally developed by Autodesk, Inc is
sometimes more desirable than the MPEG animation format, particularly for
computer-generated animations, as relatively large (640x480) movies can be
played back at reasonable speeds on X11 workstations, PCs and Macs.

Playing FLI/FLC movies:
Get one of the following players:
X11 workstations: Xanim
Mac: QuickTime 4
Windows 3.1: Waaplay
Windows 95/98: Waaplay , or QuickTime 4
Win NT PowerFLic , or QuickTime 4
If you are running a graphical Web browser and you want to view these movies
"on the fly", you probably will need to tell your browser to recognize .fli
and .flc extensions as MIME type video/fli, and you will also need to tell the
browser to use the appropriate FLI/FLC player when it encounters type MIME
type video/fli.
For example, if you are using an X windows browser, you need to first add
the following line to the file /usr/local/lib/mime.types or $HOME/.mimetypes:
video/flc flc fli
If you are serving FLI/FLC files, you should add the above line to the mime.
types file in your httpd's conf directory so that the server can identify
FLI/FLC movies to browsers. Then add the following line to
/usr/local/lib/mailcap or $HOME/.mailcap:
# This maps all types of video *other than MPEG* to the viewer 'xanim'.
video/*; xanim %s
I sometimes compress FLC Files greater than 1 Mb with UNIX compress or GNU's
GZIP, both of which can be uncompressed with GZIP . If you are using X-windows
Mosaic, the movies should uncompress on the fly. Otherwise, you may need to
select "load local", download the file, then unzip or uncompress before
viewing. If you are really bummed about not being able to view these movies on
the fly on your PC, let me know and I'll change them back to their
uncompressed form.
------------------------------------------------------------------------------
Making FLI/FLC movies:
FLI/FLC makers generally take a bunch of image files that each contain a
single movie frame and combine them into a FLI/FLC movie. Since FLI/FLC movies
are 8-bit, there are usually some options for picking the optimal colormap
from images that have more than 8-bits of color information or have separate
8-bit palletes for each image.
Here are the FLI/FLC makers I use:
For DOS, I usually use the excellent shareware program called Dave's Targa
Animator . Don't let the name fool you -- it can do alot more than just
animate Targa images. It also takes GIF, PCX and several other image types. It
will even interpolate between frames and other cool stuff.
Also for DOS, I have used the versatile DISPLAY program. It's a combination
image and movie viewer, splitter, transformer, you-name-it. Did I mention that
it can make FLI/FLC movies?
For Windows 95/98/NT, OS/2:
VideoMach (formerly Fast Movie Processor) is a simple to use convertor that
will convert frames into .flc or formats like AVI, MPEG and others.
MainActor makes FLI/FLC, AVI, MPEG and converts between different types with
lots of supported CODECS.
For UNIX, get PPM2FLI . This encodes FLC movies taking PPM, PGM, PBM or FBM
files as input, and also includes a FLC decoder to turn FLC movies into
individual images. If your movie frames are in some other image format, like
.gif or .pcx, you will also need the NetPBM image conversion & manipulation
programs .
If you are interested in a complete animation package (with modeling and
rendering tools) that generates FLI/FLC files, you might check out
Autodesk's 3D Studio VIZ.
If you are serving your FLC files up on the web, you might consider installing
Klaus Ehrenfried's Java applet which can play Fli/Flc animations within
HTML pages without the need of plugins.
------------------------------------------------------------------------------
Assorted FLI/FLC utilities
The following programs convert FLI/FLC to other movie forms directly
(GraphicConverter), or allow one to split the FLI/FLC into individual frames
and then generate another movie format (DISPLAY & PPM2FLI).
VideoMach (formerly Fast Movie Processor) is a simple to use convertor that
will convert frames into .flc or formats like AVI, MPEG and others.
MainActor for Windows 95/98/NT reads, creates and converts between just
about any movie and image format: FLI/FLC, AVI, MPEG & QuickTime. Lots of
supported CODECS too!
GraphicConverter: A Mac program to convert FLI/FLC to QuickTime.
DISPLAY: A DOS Program to convert FLI/FLC to individual images.
FLI2GIF: A PC Windows Program to convert FLI/FLC to an Animated GIF Format
to play directly on a Web page.
WINFLI: Another PC Windows Program to convert FLI/FLC to animated GIF format
(also contains a very simple FLC player).
UNFLI: A UNIX program to convert FLI/FLC to individual images. Part of the
PPM2FLI package.
