VFD(tm) Video for DOS Release 1.7 (5/05/95) 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 .RDI files (RIFF DIB) 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) Zsoft .PCX files (8 & 24-bit) *registered version* Autodesk .FLC and .FLI files (all) Windows .AVI files (RLE and 8, 16, & 24-bit DIB) 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 & DIB 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 DIB, n=2 RLE, n=3 16-bit DIB, n=4 24-bit -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% -Kn Keyframe interval n=1 to 65535 (Default is no keyframes) -Bn Backward n=1, pingpong n=2, mirror n=3, flip n=4 (B1,B2:numpic) -Rn Resize n=1 1/2, n=2 2x n=3 override dflt FLI aspect correction -Cn Color count n=2 to 255 (default=256) -Hn Hilite promotion (range 0 to 255) Use to override default. -Dn Dither (intensity range 0 to 255) Use to override default. -L±n[,c] Luminance n=1 to 255 (+ lite, - dark) (c=r,g,b: red,green,blue) -Wn Windows id palette n=1 mapped (default), n=2 not map, n=0 no id -Fn Fixed Windows id pal n=1 Indeo, 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) TRANSPARENT_r,g,b (the rgb color will be transparent - AVI only) TRANSPARENT_OFF (turn transparent 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 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. A default Hilte and Dither value is used if the color count exceeds 255 and no Hilite and Dither values are given on the command line. The default is replaced by the command line values when they are given. Params of -H0 and -D0 will disable the defaults. 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 Indeo Win 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 '-L±n[,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 Mirror Resize 2x Crop Aspect 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 DIB. For 16 & 24-bit AVIs, save the file as a 16 or 24-bit DIB. 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. Capture files created with a capture card may be converted to full frame compression option for processing with VFD. 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). Note: MS VidEdit 1.1 is included as a free bonus with the registered VFD. 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. MS 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. RLE delta input files should not be used with the Backward, Pingpong coMpress, or Total (where n1 > 1) options. CHROMA KEY OVERLAYS: Titles, copyright notices, etc. may be added to AVI motion video using transparent RLE delta overlays. First, make a title frame using any paint or drawing program, and save it as TITLE1 (in RLE image format). Extract a RLE image series from the target video. Then create a make file using the TRANSPARENT_rgb keyword to set the title frame background invisible. The makefile (pretty.mak) should look like this: first.rle ;first frame renamed TRANSPARENT_0,0,0 ;black title1.rle ;title frame REPEAT_20 ;optional TRANSPARENT_OFF pretty*.rle ;second thru last frame 'VFD pretty -a2' will produce a new AVI with the title frame overlaying the first frame. 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. See Converting AVIs for info on how to obtain a free copy of VFW. AVITXT: AVITXT.EXE adds plain text comments to AVI files. The comment text is limited to 28,000 bytes, and is padded to a 2Kb boundary by default. Existing comment text may be replaced with AVITXT. To remove comments, use AVITXT with a text file of zero length (as created with DOS EDIT). The Shareware version is limited to DIB, RLE, and msvc AVIs. The AVITXT included with the registered VFD will add comment text to all 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 '-L±n[,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 8-bit color and save as a 8-bit compressed TGA file. Then use VFD with Highlite promotion to render the TGAs. PSP.ZIP is avaliable on CompuServe in the GRAPHSUP forum, Format Conversion library. 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.
