System Requirements:
QuickView Pro is a 32 bit protected mode program and therefore needs at 
least a 80386 processor and a VGA card. It will run under DOS 3.0 or 
better, or in a DOS shell under Windows 95/98/ME and OS/2. The DOS support 
of Windows XP or later however is restricted so that QuickView will only 
run with limitations. Most ISA sound cards are supported as well as some 
PCI sound cards. You should take care that you have a VESA 2.0 compliant 
graphics card or driver as it has a high influence on the video playback 
performance. Videos are scaled to full screen either by software or by 
hardware if one of the supported graphics chips is present. These are most 
chips from the following companies: 3Dfx Interactive, Inc., ATI (3D Rage, 
Rage 128, Radeon), Matrox, Neomagic Corporation, nVidia Corporation (TNT, 
GeForce), S3 Inc., Trident Microsystems. 
For a complete list see: "chipsets.txt". 


Installation:
Simply place all files of the package in the same directory. That's it! 
QuickView will automatically detect your machine, memory and graphics card. 
Since there is no installation necessary, the uninstall can be done easily 
by deleting all files.

For sound support with a Sound Blaster or compatible you must have the 
Environment variable BLASTER set containing port address, IRQ and DMA channel 
or the appropriate ULTRASND variable for the Gravis UltraSound. A Windows 
Sound System card is autodetected. There are external drivers for PCI sound 
cards that you can download from http://www.multimediaware.com/qv/snddrv/. 


Command Line Format:
The command line format to run QuickView is:

QV [options] [filename]

filename can be a file that QuickView views or a name that contains the 
wildcards * and ?. 
Example: QV -A -Q2 VIDEO.AVI

Options: 
An Option can start with a "-" or a "/". This documentation uses "-". All 
parameters are case-insensitive.

-M Select 25 lines menu mode. QuickView uses 50 line menu mode by default. 
For 25 lines you can use the -M option.

-V Don't use VESA. QuickView autodetects many graphics cards and uses VESA by 
default. The -V option tells QuickView to not use the VESA interface if 
installed, but if you want to use HiColor or TrueColor modes the VESA interface 
must be used. If your graphics card does not support VESA you can use a VESA 
TSR like Scitech Display Doctor (see below).

-B Don't autodetect video chipset. This also disables the detection of video 
chips that are supported with hardware acceleration.

-Rx Select screen resolution:
x=1: 320x200
x=2: 640x480
x=3: 800x600
x=4: 1024x768
If a mode is not possible auto select will be used.
default: auto select.

-Wa,b,c,d,e Set sound card parameters
a: card type:
a=0: no sound card
a=1: Sound Blaster or compatible and ESS
a=2: Gravis UltraSound Classic or Max
a=3: Windows Sound System
a=4: enforce Sound Blaster Pro use
a=5: encorce Sound Blaster 2.0 use
(You can also just use -W4 and -W5 as option. The other parameters will be 
taken from the BLASTER environment variable.)
a=6: PC speaker sound. Note that the quality is low and that it doesn't work 
under Windows
b: port address, hexadecimal
c: IRQ
d: DMA (for the Sound Blaster 16 or higher: Low DMA channel)
e: high DMA channel (only for the Sound Blaster 16 or higher)
Example: "-W1,220,5,1" for Sound Blaster, Port 220h, IRQ 5, DMA 1
For no sound card, use -W0

Use the -W parameter only if really necessary, for example if the program 
crashes when it tries to autodetect a sound card. Please note that your system 
might crash if you use wrong parameters.

-WE$filename Use external sound driver, example: -WE$D:\QV\VIA.SDR

-Ox Set audio volume (x between 0 and 15).

-@x Playlist file where x is a file name. Example: qv -@playlist.txt
MP3 playlists (M3U files) can also be played: qv -@playlist.m3u
A playlist file is a plain text file that contains file names with parameters 
that QuickView shall play one after another. The meaning of the parameters for 
each file in the playlist file is the same as described under Command Line 
Format. The playlist file must be a plain text file that you can write with 
any editor. It must not be a Word file or anything similar. Command line 
parameters that you give qv.exe at start are valid for the whole playlist file.
Example: qv -R2 -@listfile.txt will use the 640x480 resolution with all pictures 
and videos in the playlist file. Parameters in a playlist file line are locally 
and only valid for the specified video, picture or sound file. You can make one 
loop if you write the following in a separate line:
:l
It stands for label and defines the position where QuickView shall return when it 
finds a
:g
This stands for goto label.
Here is an example of a playlist file: -R2 -T100 picture.jpg
:l
-N -K0 video1.mpg
-N -K0 video2.mpg
:g
It will display picture.jpg with 640x480 resolution for one second. Then it will 
play video1.mpg and video2.mpg without scaling in a never ending loop while 
picture.jpg is still visible in the background (if it wasn't overwritten by a video). 
Note: You can leave this loop only with ALT+X.
The non-registered version allows to view at most 10 files with the playlist feature.

-A No sound with videos.

-P Preload and decompress AVI sound in advance. This will give better performance 
with slower systems, especially if the sound is compressed. However, you have to 
wait some time until the video begins to play. Preloading the sound will work only 
if you have sufficient memory of course. Thus, you won't be able to preload the 
sound of a whole movie since this would require memory in the gigabyte range. You 
won't get any sound in this case.

-D Don't drop frames if behind with AVIs and MPEGs. The sound will automatically be 
disabled with this option.

-4 Don't use 320x240 mode. QuickView will use the 320x240 mode with all color depths 
by default if the video or picture is larger than 320x200. The 320x240 video mode 
with 256 colors is available on every VGA card, however with HiColor and TrueColor 
only if they are supported by the VESA BIOS. 320x240 is a non-standard VGA mode and 
may cause problems. Turn off 320x240 support in this case.

-Qx Video quality:
x=0: TrueColor
x=1: HiColor
x=2: 256 colors
x=3: Grayscale
For details see under video options below. The default is HiColor if it was not 
changed in the config file. Note that not all video codecs offer TrueColor or 
HiColor quality.

-Kx Type of video scaling:
x=0: No scaling
x=1: 2x scaling
x=2: Software full screen scaling
x=3: High quality scaling with DivX and H.264 codecs and MPEG-1 files, otherwise 
normal software full screen scaling
x=4: Hardware full screen scaling. This is available with certain graphics chips only. 
If hardware scaling is not supported with your hardware, then software scaling 
will be used.

Default: Full screen hardware scaling if available, otherwise software full screen. 
Note that software full screen requires some CPU power. If you get frame drops, select 
no scaling with -K0

-UAx Select audio stream of AVI videos. x=0 is the default stream.

-UB Use banked video memory access instead of linear frame buffer. Use this option 
if QuickView crashes while video playback or when showing pictures. Some VESA BIOSes 
(for example certain SiS chips) are buggy.

-UCx Select character set for subtitles. x=0: Western, x=1: Eastern, x=2: Cyrillic 
(Win-1251), x=3: Cyrillic (KOI-8R)

-UD Disable MTRR register programming

-UF Don't show pictures full screen.

-UG Use different volume programming for Sound Blaster compatible sound chips

-UH Don't use the hlt command if the system is idle. Using hlt helps to save power 
(important for Notebooks) and keep the CPU temperature low.

-UI Don't check in advance if the sound with AVI playback will be decoded just in 
time but assume that there will be no sound buffer underruns.

-UJ Use index to sync AVI video and audio during playback.

-UK Use the BIOS to query the keyboard instead of direct programming. This way e.g. 
infrared remote controls can be used.

-UM List only supported files in the menu.

-UO Use speaker output instead of lineout with external sound driver.

-UPx Sound parameters (not supported by all sound chips):
          -UPB8 Enforce 8 bit sound
          -UPB16 Enforce 16 bit sound
          -UPC1 Enforce mono sound
          -UPC2 Enforce stereo sound
          -UPFx Enforce sound sampling frequency x Hertz, example: -UPF22050
          -UPH Enforce half sampling frequency

-UR Keep aspect ratio when showing pictures and videos full screen.

-US Don't synchronize video playback with the vertical retrace of the monitor. If you 
use this option you might get tearing artefacts. However, synchronizing takes some time. 
If you're getting framed rops you should try to use this option.

-SUBx Select subtitle file for AVI. Example: -SUBd:\videos\film.sub
Supported subtitle files are: SRT (SubRip), SSA (Sub Station Alpha), SUB (MicroDVD), 
SUB (SubViewer), TXT

-VCDx Start VideoCD playback. x is the track number. If you don't give a track number, 
track 2 will be assumed for VideoCDs and 1 for CD-i.

-VCDSx Same as -VCDx but the second CD drive will be used.

-MMX Don't use MMX enhancements for video playback.

-RND Shuffle Play. Play the files given with wildcard in a random order (at most 10 
in the non-registered version). Example: QV -RND *.MP3

-LOW Lower quality for slow computers. It is equivalent to -UPB8 -UPC1 -UPH -US -K0 . 
Moreover, it limits the colors to HiColor.

The following parameters are only available with the registered full versions, i.e. 
neither with the shareware version nor in the registered light version:

-C Don't switch to text mode after playing.

-N Don't set video mode. This can be used together with -C, -J, -X and -Y to display 
graphics around the video for example. You should take care that the color depth of 
the video mode that is set when you start QuickView is equal to the one that would 
be selected for the video or picture.

-Fx Start AVI/MPEG at frame x or MP3 at time x (in 1/16 seconds). Example: -F137

-Gx End AVI/MPEG at frame x or MP3 at time x (in 1/16 seconds).

-FPx Similar to the -Fx option, however means the x percentage of the total length here.

-Lx Loop video and MP3 x times respectively, 0 means until key pressed, default for 
AVI/MOV/MP4/MPEG/MP3 is 1, default for CEL/FLI/FLC/DL is 0, default for GIF is the 
loop counter in the GIF.

-Sx Set playback speed of AVI, CEL, DL, FLC, FLI and MPEG files. x is the time between 
two frames in microseconds.example: -s100000 gives 10 frames per second. The sound of 
videos will automatically be disabled with this option.

-Tx Wait x/100 seconds after playing, 0 means wait for keypress.

-Jx,y Size of the video or picture window, x is the horizontal size and y the vertical 
size. You can also use this option to correct the aspect ratio of a video, e.g. 4:3 
instead of 16:9. Example: -J300,200

-Xx Position video or picture window at horizontal position x (must be a multiple of 4).

-Yx Position video or picture window at vertical position x.

-Zx Mouse and keyboard playback control. Each bit of x triggers a certain mouse or 
keyboard event:
bit 0: Mouse move stops
bit 1: Left mouse button press stops
bit 2: Right mouse button press stops
bit 3: Middle mouse button press stops (not supported with all mouse drivers)
bit 4: Every key press stops
bit 5: Ignore keyboard while playback (not evaluated if bit 4 is set)
bit 6: Do not read keyboard at all while playback
Example: stop video when mouse is moved or the left mouse button is pressed would be -Z3

-CAx,y Address of a callback routine. The callback routine will be called periodically 
during playback so that programmers can call QuickView as external program and get full 
control over the playback.
x=R: Real mode address, then y in the form segment:offset
y=P: Protected mode address, then y is the linear address.
Further details upon request.



The Menu:
QuickView always shows you all the files in the current directory, along with all the 
visible subdirectory names. The arrow keys will move the file selector bar around. 
CTRL+right or left move the file selector to the next or previous supported file 
respectively.

By pressing a character the file selector bar jumps to the first file starting with 
that character. Use lower case for files, upper case for directories. A mouse is not 
supported.

To view a file or change a directory just hit Enter. If you try to view a file 
QuickView does not handle nothing will happen. If you have tagged some files QuickView 
will view these files without going to the menu in between. Hit Enter or Tab if you 
want to view the next file and Backspace for the previous one. Esc breaks and returns 
to the menu.

More keys during file selection: 

ALT+D: Change drive. A drive selection box will appear, prompting you for the drive 
letter you want to log onto. QuickView will attempt to change to the desired drive. 
If an error occurs, QuickView will remain logged onto the current drive.

F1 :Help.

F2 :Display information about the system.

F3 or ALT+I:Get information on the currently selected file.

F4 :Software Information.

ALT+O:Change options of QuickView. For details see below.

+ - :Increase or decrease resolution respectively. The currently selected resolution 
is highlighted. "Automatic" automatically selects the lowest resolution which will 
display the whole picture if possible. 

Space: Tag/untag the current file.

ALT+T: Tag all files in the current directory.

ALT+U: Untag all files.

ALT+S: Shuffle Play. All files in the current directory are played in a random order. 
If you've already tagged files, only these files will will be played in a random order.

ALT+L: Load subtitle file that will be played together with the next AVI video.

ALT+M: Toggle between listing of all files and supported files only.

ALT+R: Reread the directory

Del : Delete file.

ALT+X: Exit QuickView.


Options in the Menu:
Press the red characters to toggle the state of the option. You can also use the 
up/down arrow keys and the Space bar. If you press "C" a configuration file is created 
or updated. You are given the option to save the command line parameters in the config 
file so that you don't have to enter them with every start. Command line options 
override the config file. Note that changing the use of VESA is only effective if you 
leave QuickView and start it again.

Include 1280x1024 mode: Some monitors (mainly older ones) don't support the 1280x1024 
screen mode. If you tell QuickView to support this mode your monitor might be damaged. 
Please consult your monitor handbook.

Use 320x240 mode instead of 320x200 if appropriate: For more details look at the -4 
command line option.

Display images full screen:
Note that 2 color pictures will not be scaled.

Keep video/picture ratio with scaling:
Use the video/picture ratio instead of the 4:3 ratio of the monitor.

Video options:
Sound support: Play the sound of the videos?

Preload Sound: Look at -P command line option.

Never drop frames: If you use this option, no frames will be dropped if the system 
is not fast enough. This option automatically disables sound.

Loop:Use this if you want an AVI, MOV, MP4, MPEG or MP3 file to start again after playing.

Sync with monitor: Tearing artefacts can be avoided if frames are only updated when 
the monitor is in VSync. Note that you might get less frames per seconds if the 
option is enabled.

Video quality: These options depend on the codec used:
Grayscale: Usually the fastest playback mode.
8 color bits: 256 colors.
HiColor: 32768 or 65536 colors depending on the graphics card's features.
TrueColor: Will give the best quality with more than 16 million colors.
Note: QuickView will use at most the amount of colors that the codec uses.

Video Scale:Type of video scaling. Available options are:
No scaling
2x zoom: The video will be played twice as big. Note that 2x Zoom might require a 
higher screen resolution so that the video doesn't appear bigger.
Software full screen: The video will be played full screen using software scaling. 
This is CPU very CPU intensive. On slower systems use one of the previous options.
HiQ software full screen: High quality scaling with DivX and H.264 codecs and MPEG-1 
files, otherwise normal software full screen scaling.
Hardware full screen: The graphics chip's hardware scaling and color space conversion 
facilities will be used to play the video full screen.

Questions & Answers:
I only see a black or garbled screen with video playback. 
Maybe the hardware video acceleration does not work (yet) for your graphics chip. 
Please use software scaling instead and notify the author.

Sound problems like:
The sound doesn't work at all.
The sound card isn't detected.
Videos stop after the first frame.
Sound parts are repeated over and over again.
The sound quality is poor.
Most of the time the reason for these problems are incorrect sound card settings in the 
BLASTER environment variable. There must be a command in your AUTOEXEC.BAT like this:
SET BLASTER=Axxx Ix Dx Hx Pxxx Tx
with
A: Sound Blaster base I/O-port,
I: IRQ,
D: DMA low channel,
H: DMA high channel (only required for SB16 or higher),
P: MIDI port (not evaluated),
T: Sound Blaster Type (not evaluated)

Usual values are: A220, I5 or I7, D1, H5.
If I5 does not work for you, try I7 and vice versa.

For the original Sound Blaster there is a program called "DIAGNOSE.EXE" which programs 
the sound card configuration according to the values in the BLASTER variable. Use 
"DIAGNOSE /S" in your "AUTOEXEC.BAT".

Under http://www.multimediaware.com/qv/sbdetect.zip there is a program that low level 
detects the Sound Blaster settings.

For the Gravis UltraSound there must be the environment variable "ULTRASND".

If your sound card is not detected properly, you can set the sound card parameter 
directly using the -W parameter.

If the system info (F2 in the menu) says that a sound card was detected but you 
can't hear it with any file then check the volume. You can increase the volume with 
"+" while playback.

If you don't get sound with videos but with MP3, WAV and VOC files then check if you 
enabled "Never drop frames". This will automatically disable sound. If you don't get 
sound with some AVI, MOV or MP4 files only this might be because they are using an 
unsupported audio codec. Check what audio codec the video uses by pressing File Info 
(F3). If you either get the message "unsupported" or "unknown" then this audio codec 
is currently unsupported. Other possible reasons are insufficient memory or a 
truncated file.

If your sound chip cannot be made Sound Blaster compatible you can use an external 
sound driver. For the current status of the supported sound chips look at: 
http://www.multimediaware.com/qv/snddrv/

Some sound cards like the ESS1868F do not work in a DOS session under Windows but only 
under pure DOS. 

The video is played jerky.
The sound is played with interruptions.
Video and sound of AVI files are not in sync.
If the video itself wasn't captured with a low frame rate, this usually indicates 
that your system is too slow. QuickView will not show all frames of the video so that 
the sound can be played without interruptions. But this can also fail if your system 
is far too slow.

In order to improve the video playback with slow systems you should use the -LOW parameter. 
It will lower the sound quality (-UPB8 -UPC1 -UPH), choose no scaling (-K0), disable 
synchronization with the vertical retrace (-US) and limit the number of colors to HiColor. 
If this is not sufficient you can select 256 colors or grayscale using the -Q parameter. 
Also, try copying the file to your hard disk instead of playing it from CD.

If there are problems with the playback of certain AVI videos, then try the -UI Option.

If you encounter audio/video sync problems with AVI videos then try the -UJ option.

Why is the video quality bad with some videos? 
This might be because you don't have a TrueColor or HiColor card or you don't have 
a VESA driver in your system. In the latter case you should use the VESA TSR for your 
graphics card or Scitech Display Doctor, available on many FTP-servers, BBSs, from 
Shareware distributors or on my WWW page. The VESA driver must conform at least to 
version 1.2 of the VESA standard. Versions prior to 1.2 of the VESA standard did 
not define TrueColor and HiColor modes.

I get memory error messages with some files. What can I do? 
Select a lower number of colors, e.g. HiColor instead of TrueColor. Turn off sound.

I can't forward and rewind AVIs. 
Either the AVI has no index or a bad index, or it does not have keyframes, or there 
is not enough memory.

The text screen is messed up after hardware scaling was used.
Scaling doesn't work properly with your graphics card. Choose a different scaling 
type than hardware full screen.

I get some lines on the graphics screen with my ATI Mach graphics card under 
Windows 95/98. 
Try M64VBE with parameter S

I get a black or garbled screen when I start QuickView. 
Try starting the program with the parameter -B.

I don't have a sound card and I'd like to hear the sound through the PC speaker. 
Use the -W6 parameter.

I like the 25 lines menu more. How can I select this mode permanently? 
Press ALT+O in the menu. Then you can select 25 lines with "5" and write a config 
file with "C".

What do I have to do to make QuickView run under Windows NT or XP?
The software will only run with limitations under Windows NT or XP. You must open 
a DOS full screen session. Some video drivers have bugs with the VESA support. If 
you only see color garbage or a black screen (because the monitor doesn't synchronize 
any more) then use a fixed screen resolution that works either by using the -Rx 
parameter or by choosing the resolution in the menu with the "+" key. Example: QV -R2 
will use 640x480 as screen resolution which works with many graphics chips. Sound 
however is still a problem under Windows XP and NT. You can try VDMSound, a soundcard 
emulator for MS Windows NT/2000 DOS boxes.

What do I have to do to make QuickView run under OS/2? 
You have to set the following definitions for the DOS session:
INT_DURING_IO: ON
IDLE_SENSIVITY: 100
HW_TIMER: ON
VIDEO_RETRACE_EMULATION: OFF
AUDIO_ADAPTER_SHARING: REQUIRED
DPMI_DAS_API: ENABLED

Make sure the BLASTER or ULTRASND environment variable is set properly. The OS/2 
Sound Blaster drivers seem to have a DMA handling problem in a DOS session which 
sometimes causes a lockup with sound output. Try to get an updated sound card driver. 
If that doesn't help, please either turn off sound or run the program under plain DOS. 
Also, some OS/2 sound drivers don't handle 16 bit sound properly. If you only hear 
a strange noise use the -w4 parameter to enable Sound Blaster Pro compatibility. 

How do I use QuickView's AVI, MOV and Audio MPEG support with Arachne (DOS WWW browser)?
You should use the APM package of QuickView that is available under 
http://www.multimediaware.com/qv/qv.apm The MIME types will be configured automatically. 

What is a codec?
Video and audio sequences are compressed and decompressed by routines called codecs 
(short for compressor/decompressor). A codec is responsible for compressing raw video 
or audio data into a format suitable for distribution. When you play the compressed 
video or audio sequence, the codecs integrated in QuickView perform a reverse role, 
converting the compressed data into images or sound that can be played on your system.

I have problems with VideoCD and CD-i playback
Not all CD drives allow proper raw reading of CDs which is necessary for VideoCD and 
CD-i playback. This especially applies to Windows. For playback of VideoCDs under 
Windows access the videos as normal files that are usually named AVSEQ01.DAT, AVSEQ02.DAT 
and so on.

On the other hand, most DOS CD drivers do not support reading of these files under DOS. 
The directory is visible but the files itself cannot be accessed. Use the -VCD command 
under DOS to play a VideoCD or CD-i.

Some CD drives spin down the motor too fast after reading. When new data is required they 
take a few seconds until they are active again. This results in playback pauses. If your 
CD driver allows to increase the spin down time you should try this.
