VFD(tm) Video for DOS
Release 1.5
Copyright (c) 1994/95 by Bob Williamson CIS 76570,2752
VFD(tm) is a DOS command-line motion video cross-compiler for creating
.FLC, .FLI and .AVI files from:
Windows .DIB files (all BMP & RLE)
Windows .BMP files (1, 4, 8, 16 & 24-bit)
Windows .RLE files (4 & 8-bit, including deltas)
IBM OS/2 .BMP files (1, 4, 8 & 24-bit)
Truevision .TGA files (8, 16, 24 & 32-bit rle & uncmp)
CompuServe .GIF files (PC & Mac 87a, 89a) *registered version*
Zsoft .PCX files (8 & 24-bit) *registered version*
Autodesk .FLC and .FLI files (all)
Windows .AVI files (RLE and 8, 16, & 24-bit Full Frames)
MPEG .RAW files produced by DMPEG.EXE v1.1 (8 & 24-bit)
VFD will extract a numpic file series from FLC, FLI, RAW, and AVI
(RLE & Full Frames only) in BMP, RLE, GIF, PCX or TGA formats. Direct
conversion of FLC, FLI, AVI and single image formats is also supported.
VFD uses an advanced method of color quantitization called Hilite
Promotion (Scaleable Adaptive, Histogram-based). Hilite Promotion
produces 8-bit motion video with high color fidelity and image
resolution from a diverse range of image files and palettes by using
scaleable quantitization (color reduction) and variable dither
intensity. Hilite Promotion can be used to create an optimum palette
containing both the most popular colors and the most diverse colors
from the input images.
Hilite Promotion was developed as a solution to the motion video color
quantitization problem of multiple images and palettes. It may be
used for building compatible Windows identity palettes for one or more
bit-mapped images to be displayed by Windows, as well as motion video.
PARAMS:
VFD options may be invoked by use of command-line parameters. The
parameters follow the infile, preceded by a space and either a forward
slash '/' or a hyphen '-'. The params may be in any order and are case
insensitive. Typing 'VFD <enter>' will display a list of the options:
VFD infile [params]
-I create .FLI (default is .FLC)
-An create .AVI n=1 8-bit Full Frames, n=2 RLE
-En Extract numpic series n=1 8-bit .BMP, n=2 .RLE delta, n=3 .GIF
n=4 8-bit .PCX, n=5,6,7: 8,16,24-bit .TGA uncmp
-Sn playback Speed in frm/sec n=0.1 to 99 (default=15)
-Ofname Outpath [d:\path\]fname (default fname=infile w/ outtyp .ext)
-Tn1[,n2] Total frames n1=start, n2=total count (disables B2 pingpong)
-Mn CoMpression n=1 50%, n=2 67%, n=3 75%, n=4 80%, ..., n=99 99%

-Dn Dither (intensity range 2 to 255)
-Lñn[,c] Luminance n=1 to 255 (+ lite, - dark) (c=r,g,b: red,green,blue)
-Wn Windows identity palette n=1 mapped, n=2 not mapped
-Fn Fixed Windows id pal n=1 256 colr, n=2 gray, n=3 hlftne, n=4 b&w
-Pn write Pal n=1 RIFF .PAL, n=2 DIB .PAL, n=3,4 AA,AAPro .COL,
n=5 PicLab .MAP, n=6 PSP .PAL, n=7 NeoPnt .PAL, n=8 generic .PAL
The infile may be any of the above listed image file formats. VFD
will read a numpic series if wildcards ('*' or '?') are used in the
file name. The infile may include the path. The output file path is
the current default. Examples:
VFD pretty00.bmp (produce a one frame .FLC
PRETTY.FLC)
VFD pretty*.rle (produce a 100 frame .FLC
starting w/ pretty00.rle
thru pretty99.rle named
PRETTY.FLC)
VFD d:\pretty\pretty??.rle -a2 -w1 (produce PRETTY.AVI with a
Windows identity palette)
VFD pretty.avi -i (produce PRETTY.FLI)
MAKEFILE:
Typing 'VFD -? <enter>' will display the following:
The infile for VFD may be a text file with the extension of .MAK which
lists the source image files and optional keywords. If a motion video
file is used in the makefile, it must be the only input image file.
The keywords are:
REPEAT_n (repeat the previous input file 'n' times)
PINGPONG (read the previous numpic series in reverse order)
BACKWARD (read the following numpic series in reverse order)
MIRROR_ON (the following frames will be mirror-image)
MIRROR_OFF (turn mirror-image off)
FLIP_ON (the following frames will be inverted)
FLIP_OFF (turn inverted off)
KEYFRAME (the following frame will be a keyframe)
CD-ROM (the AVI video chunks will be padded for CD-ROM playback)
CROP_n1,n2,n3,n4 (n1=top, n2=left, n3=width, n4=height) zero base
TRANSPARENT_r,g,b (the rgb color will be transparent - AVI only)
TRANSPARENT_OFF (turn transparent off)
Keywords are not case-sensitive. The comment character is a semicolon.
Example text of PRETTY.MAK:
;216 frames, 320x240, identity pal
pretty.pal
d:\pretty\pretty00.bmp
REPEAT_8
d:\pretty\pretty??.bmp
d:\pretty\pretty99.bmp
REPEAT_8
PINGPONG
The above example will produce PRETTY.FLC containing 10 frames of
pretty00.bmp, 98 frames of pretty01.bmp thru pretty98.bmp, 10 frames
of pretty99.bmp and 98 frames of pretty98.bmp thru pretty01.bmp. The
palette file pretty.pal will be used for the motion video palette.
PINGPONG repeats the previous numpic series in reverse, omitting the
first and last frames.
The maximum frame count is 65535. The maximum makefile size is 16kb.
Numpic series with the same base name are limited to a maximum of 5460
frames. VFD reads stdin for response to input prompts. VFD may be
invoked in a batch file (.BAT) using redirection of a text file for
input response. The system date, time and command line params are
inserted as the first comment line in the makefile each time the
makefile is processed by VFD. Input image files are opened read-only.
The .MAK extension is not required on the command line. 'VFD pretty'
is equivilent to 'VFD pretty.mak'.
HILITE PROMOTION:
Any combination of input image types and color formats (1 to 32 bit)
may be combined in a VFD makefile. If the total color count exceedes
256, Hilite Promotion and dither should be used to obtain the optimum
output for 8-bit video. VFD builds a popularity histogram of all the
colors from the input images. The motion video palette consists of the
256 most popular colors less the Hilite Promotion value. The Hilites
are then added to the motion video palette from the remaining colors in
the histogram. The Hilites are selected as those colors in the
histogram having the greatest difference from the colors already
included in the motion video palette. If the '-Cn' (color count) option
is used, the Hilite value is subtracted from the color count. Black, by
default, is always the first color in the motion video palette.
A Hilite value of 255 (true-cut) will produce results similar to the
standard unbiased median-cut method of color reduction. With Hilite
promotion, the palette colors are actual colors from the input images,
not averaged colors. Lower Hilite values (-H128) will often produce the
best results for motion video and generate a smaller file, as less
dither is required. The lower value guarantees inclusion of the true
most popular colors in the video palette. If reducing a single image,
or making a slide show, use -H255 -D128 for best results.
Motion video created from digital video capture (16/24-bit color) can be
converted to 8-bit color motion video with very good results by using
Hilite Promotion and dither. Start with -H128 -D20 and adjust up or
down to produce the best result. For ray trace input, start with -H160
-D8. As Hilite value increases, the dither requirement decreases.
DITHER:
Dither will reduce or eliminate 'color banding'. Dither may be used
even when the total color count is less than 256.
VFD uses the 'Floyd-Steinberg' dither pattern in alternating direction
(serpentine). The dither intensity (-Dn) is the maximum difference
between the true pixel value and the motion video palette value that
will be used in the error dispersion. Lower dither values produce less
'background animation'.
COMPRESSION:
Motion video compression (data rate reduction) may be achieved in two
ways: Reduce the data content (image quality) of each frame, or by
reducing the frame count and the playback speed by a corresponding
amount. VFD uses the second of the two compression methods. VFD motion
video image quality is always 100%. The range (-Mn) is n=1 50% to n=99
99%. Compression may be used with Extraction of a numpic series as well
as motion video output. Example:
-M1 write 1, skip 1, write 1, ... Speed/2 50%
-M2 write 1, skip 2, write 1, ... Speed/3 67%
-M3 write 1, skip 3, write 1, ... Speed/4 75%
...
-M99 write 1, skip 99, write 1, ... Speed/100 99%
Use of compression is recommended when processing 24 or 30 frame/sec
input.
PALETTES:
The motion video palette may be output with the '-Pn' param. VFD reads
and writes the following palette formats:
-P1 RIFF .PAL (VFW PalEdit)
-P2 DIB .PAL (Windows Paintbrush)
-P3,4 AA,AAPro .COL (Autodesk Animator, AA Pro)
-P5 ascii .MAP (PicLab - DOS Public Domain)
-P6 ascii .PAL (Paint Shop Pro - Windows Shareware)
-P7 ascii .PAL (NeoPaint - DOS Shareware)
-P8 generic .PAL (Improcess - DOS Shareware)
The programs in parentheses are applications that can read and edit the
specific palette format. Ascii palette files may also be edited with a
text editor. The edited palette may be used as the motion video palette
by including it as the first file in the makefile. The Color count
(-Cn) and Windows id pal (-Wn) params are disabled when a palette is
read from the makefile. Windows Paintbrush will only read DIB palette
files with 28 colors maximum.
ID PALETTES:
The Windows identity palette option (-Wn) will add the 20 reserved
Windows system colors to the motion video palette. The 20 colors are
subtracted from the color count prior to subtracting the Hilite
Promotion value. The identity pal may be mapped (-W1) or not mapped
(-W2) to the motion video palette. VFD maps the closest color in the
motion video palette to the color in the input image using the spherical
distance method.
Some motion video, while requiring the identity pal for compatibility
under Windows, will look better when mapped only to the colors from the
input file (-W2).
FIXED PALETTES:
VFD provides 4 fixed palettes: -F1 = 256 color Windows identity pal
-F2 = 32 color grayscale Win id pal
-F3 = 32 color halftone Win id pal
-F4 = black & white Windows id pal
The -F1 default is mapped identity pal. The -F2, -F3 and -F4 defaults
are not mapped identity pal. The defaults may be overridden by use of
the -W1 or -W2 params. Example:
-F4 -W1 will use the 20 color Windows
identity palette (b&w are id colors)
-F4 -D128 for dithered b&w output
The Luminance '-Lñn[,c]' param color channel option '[,c]' may be used
to change the tint of the grayscale and halftone palettes. The '-Cn'
color count param is disabled when a fixed palette '-Fn' is used.
RESIZE & ASPECT:
The '-R1' param will halve the vertical and horizontal dimensions of
the input image. Example: 640x480 -> 320x240. The -R2 param will
double the vertical and horizontal dimensions of the input file.
Example: 320x240 -> 640x480.
VFD prompts for screen aspect correction to high resolution mode if
the source files are 320x200 and the output format is .FLC or AVI. If
the source files are not 320x200 or 160x100 and the output is .FLI, the
images are corrected from high resolution mode to FLI aspect by default.
Default FLI aspect correction may be overridden by using the -R3 param.
The maximum input and output image size is 1024x768. Input image size
for .FLC and .AVI output must be consistant. Input image size for .FLI
output may vary from a maximum of 640x480 (the output for .FLI will
always be 320x200, with image centered).
Sequence of geometic operations: Resize 1/2

CONVERTING AVIs:
Many .AVI files are compressed with formats for which there are no
Public DOS drivers. These files must be converted to RLE or Full
Frames with VFW VidEdit or a similar Windows program for use with VFD.
If the AVI is 8-bit color, save the file as RLE or 8-bit Full Frames.
For 16 & 24-bit AVIs, save the file as a 16 or 24-bit Full Frames.
When saving in RLE format for VFD input, set the target to custom, no
data rate, no keyframes, no CD-ROM padding, and set quality at 100%.
If the data rate is not set to a high value, data may be lost when
converting to RLE compression using VidEdit.
AVIs created with VFD may be converted to other compression options
with VidEdit. If VidEdit returns 'out of memory' errors when converting
RLE compressed AVIs, use VFD to add keyframes (-K15 -A2).
If you do not already have Video for Windows, it is free for the asking,
and includes VidEdit, PalEdit, and WavEdit. (VFW is no longer offered for
retail sale.) On CIS, download JSCD.TXT, 305 bytes, 13-Jul-94, from the

RLE DELTAS:
Deltas are the differences between the current frame and the previous
frame. Delta encoding uses line and column skips to create
transparency. When a delta input series is processed, the frames are
overlayed with the transparent portion unchanged from the previous
frame. Delta input series may not be dithered with VFD. If dither is
required, the delta series should be extracted from a motion video that
was created using dither.
VFW BitEdit, Paint Shop Pro (Windows Shareware), and AAWIN (Freeware
Autodesk player for Windows) read and display RLE deltas correctly.
The first frame of a RLE delta series is a keyframe (opaque), and the
following frames are all deltas (transparent except for changes from the
previous frame). Full frame (opaque) RLE series may be extracted by
using the Keyframe param: -E2 -K1.
CHROMA KEY OVERLAYS:
Titles, copyright notices, etc. may be added to motion video using
transparent RLE delta overlays. First, make a title frame using any
paint or drawing program, and save it as TITLE1 (in any VFD compatible
image format). Then create a make file using the TRANSPARENT_rgb keyword
to set the background invisible, and extract the RLE delta. The makefile
(title1.mak) should look like this:
TRANSPARENT_0,0,0 ;black
title1.bmp
Now extract a RLE delta series from the motion video.
Example: VFD pretty.avi -e2.
Rename the first RLE image (pretty00.rle) as first.rle. Create a
makefile (pretty.mak) as follows:
first.rle
title001.rle
repeat_20 ;optional
first.rle ;optional
pretty*.rle
'VFD pretty -a2' will produce a new AVI with the title frame overlaying
the first frame.
If the color count exceeds 256, use the '-Cn -Hn -Dn' params to reduce
the color count for the RLE delta series extracted from the orginal
motion video.
SPEED:
VFD may be used to produce slideshows as well as motion video. Playback
speed range is from 0.1 to 99 frames/sec. Fractional rates above 1
frame/sec are not supported. Some .FLC & .FLI players do not accept
speed values less than 1 frm/sec. VFD produced .AVIs with speeds less
than 1 frm/sec may be converted with VFW VidEdit to other compression
types and retain a speed of less than 1 frm/sec, even though VidEdit
v1.1 will only set rates of 1 to 99 frames/sec. Example:
-S.1 = 10 seconds per frame
-S.2 = 5 seconds per frame
-S10 = 10 frames per second
When using VFD to create looping AVI slideshows, the REPEAT_1 makefile
keyword should be used to repeat the last frame for play with Win MCI.
DATA RATE:
The data rate required for playback is displayed for .FLC, .FLI. & .AVIs
when they are rendered by VFD. The first frame of .FLCs & .FLIs is
ommitted from the calculation because it is displayed only one time,
and then replaced by the ring frame. The ring frame is a delta of the
last and first frames. AVIs do not have a ring frame.
The coMpress (-Mn) param may be used with a corresponding percentage
reduction in playback speed to reduce the data rate (and file size)
while maintaining the same apparent speed.
TOTAL FRAMES:
If extracting from motion video when the start frame (-Tn1) is greater
than 1, the first extracted frame will be a delta. To make the first
frame a keyframe, use VFD to create a video with a Keyframe interval
(-Kn) syncronized with the start frame value (n1), and then the start
frame will hit the keyframe. Example: to extract a 100 frame FLC
starting at frame 157, use 'VFD pretty.flc -k157 -otmpfle', then 'VFD
tmpfle.flc -t157,100 -opretty2'.
If the Total frames param is used with the Backwards param (-B1), the
start frame is the highest numbered frame defined by the Total frame
param. Example: to skip the first file in a 100 frame series using the
-B1 param: -T1,99. (its backwards)
KEYFRAME INTERVAL:
Keyframes (-Kn where n=1 to 65535) and the KEYFRAME makefile keyword may
be used when creating FLC, FLI, RLE compressed AVI, and for RLE delta
extraction. The default is no Keyframes. Keyframes may be useful in
video editing, but are not necessary for playback in VFD produced motion
video, as the image quality is always 100%.
Keyframes may also be useful in AVIs with a programmed or script-driven
player that seeks to specific frames in response to user input.
Extraction of all full frame RLE images may be accomplished by using the
-E2 -K1 params.
PADDING:
Padding will improve the data through-put of AVIs when played from
CD-ROM. To add padding, place the 'CD-ROM' keyword in the makefile
prior to the image files. The default is no padding. The CD-ROM
keyword is ignored for FLC and FLI output.
CTRL-BRK:
Use of CTRL-BRK will terminate VFD at any point in processing.
AUDIO:
VFD skips over audio tracks in input files. VFW VidEdit and WavEdit or
similar Windows programs may be used to add audio to VFD produced .AVIs.
MPEG:
DMPEG v1.1, a Public Domain MPEG viewer and extractor by Stefan Eckart,
is included with VFD. DMPEG.EXE will extract a .RAW file from MPEG Type
1 files (see the DMPEG.DOC file). For best results, the .RAW file
should be extracted in 24-bit format for VFD input (DMPEG -d4). VFD
Hilite value of 128 and dither value of 20 usually produce very good
results from 24-bit RAW input. Compress (-M1) and Speed (-S15) will
convert the frame rate from 30 frm/sec to 15 frm/sec while retaining the
apparent speed of the origional MPEG video. Many .RAW files can be
compressed even more by using '-M2 -S10' or -M3 -S8'. The Luminance
param '-Lñn[,c]' will be useful with some MPEG conversions.
JPEG:
VFD does not accept .JPG input files. JPG files are 24-bit color lossy
compression and must be converted to another file format for input to
VFD. For best results, use Paint Shop Pro (Shareware by JASC, Inc.), to
reduce the JPG file to 16-bit color and save as a 16-bit compressed TGA
file. Then use VFD with Highlite promotion to render the TGAs.
Another option producing good results is to use JPG2GIF v2.0, a Freeware
program by Handmade Software. JPG2GIF is a DOS command-line utility
that may be run in batch mode to convert JPG to GIF. The programs are
avaliable on CompuServe in the GRAPHSUP forum, Format Conversion
library, as PSP.ZIP and GIF2JP.ZIP.
MEMORY & SYSTEM REQUIREMENTS:
VFD.EXE is a DOS real-mode application requiring 500Kb free conventional
memory and 96Kb XMS memory for processing 320x200 images. Larger image
sizes require additional XMS memory.
DOS 3.1 or greater, 80286 or greater, 4Mb RAM required. At least 2Mb
XMS memory should be configured using HIMEM.SYS or equivilent. A SVGA
video card is required to play 256 color .FLC and .AVI files. FLI files
use only the standard VGA video modes. The VFW runtime and 8Mb Ram is
required to play AVIs with the Windows v3.1 MCI player.
MOTION VIDEO SOURCES:
The following CompuServe forums are sources for motion video:
ENERGY: AVI
ASOFT: FLC, FLI
GRAPHDEV: FLC, FLI, MPG, AVI
