but you should select a lower frame rate or a
smaller video image size. This is set in the
"Record Setup - Real Time" panel of the Video IN
Recorder application. 12MB of memory is required.
Recording Indeo real-time movies should not be
attempted on a 386 or any machine without a math
coprocessor if a Video Blaster, Super
VideoWindows, or Video Magic adapter is being
used.
A 33MHz 386 system or higher is recommended for
frame-step recording. 12MB of memory is required.
Refer to the RECORDING VIDEO section for a description
of real-time and frame-step recording.
INSTALLATION
____________
To install Video IN from the OS/2 Bonus Pack, use
the Bonus Pack Installation program. Refer to the
Bonus Pack README file and documentation for more
information about installation.
You may wish to familiarize yourself with the
following sections in this README before
installing Video IN:
* KNOWN LIMITATIONS
* SPECIFIC VIDEO CAPTURE ADAPTER INFORMATION
The following notes apply if you do not select any
video capture adapter support during installation:
* To record from a file in the Video IN Recorder
application (described later), you must first
open a source file, then select New from the
File menu for recording to be enabled.
* You may observe the message "Stream handler cannot
be loaded." If you receive this message, then
add the following line to your CONFIG.SYS file:
DEVICE=d:\MMOS2\VCSHDD.SYS
where d: is the drive containing the MMOS2 directory.
RECORDING VIDEO
_______________
After you after have installed the necessary hardware,
OS/2, and Video IN, you can now record video.
The Video IN Recorder, which is installed in the Multimedia
folder, lets you record video to your hard disk, using
two different techniques:
1. Real-time recording, in which video is captured
from a playback device at normal speed. The
advantages of this method are simplicity in
recording video and compatibility with a
wider range of less expensive video players
(such as VCRs). The disadvantage of this
method is slightly lower playback quality.
2. Frame-step recording, in which video is captured
on a frame-by-frame basis, with audio added
in a subsequent step. The advantages of this
method include smoother playback and smaller
files sizes. The disadvantage of this method
is that it requires more advanced (and usually
more expensive) playback hardware which supports
frame-stepping.
The Video IN Recorder also allows you to edit
video clips, by deleting, cutting, copying, and
pasting portions of videos. You can also "record
from file", which allows you designate another
supported AVI file as the source to be 'recorded'
into a new file, or perform "bitmap capture", which
lets you create a bitmap from a given frame of video.
REAL-TIME RECORDING
To produce a video output size of 320x240, a
maximum output frame rate of 8 frames per second
is recommended. To produce a video output size of
160x120, a maximum output frame rate of 15 frames
per second is recommended.
Note: The maximum frame size for real-time
recording is 320x240. Larger frame sizes
should only be used to capture bitmaps.
It is recommended that you disable the system
sounds before recording video. To disable system
sounds:
1. Select the System Setup or the Multimedia folders.
2. Select Sound.
3. Uncheck Enable system sounds.
When you begin recording, there might be a few
seconds of delay time before recording actually
begins. "Cue for record" can minimize this delay.
To cue for record, select "Cue for record" on the
Control menu.
Be sure you have enough hard disk space before you
start recording. If you run out of hard disk
space, the video file might not play back
properly. Saving a recording can require twice
the hard disk space as actually storing the file.
The amount of hard disk space required depends on:
o Length of the recording
o Frame rate
o Image size
o Compression type
o Compression quality settings
Under normal circumstances with default settings,
a 160x120 Ultimotion real-time recording requires
approximately 10MB of hard disk space for each
minute of recording.
Temporary files which are creating when recording
a new video are stored in the path specified in
the Multimedia Setup application in the Multimedia
folder. To change this path (for example, to a
drive with plenty of space), open the Multimedia
Setup application and change the field entitled
"Multimedia work path" to point to a drive and
directory with plenty of space. Occasionally,
temporary files beginning with 00000000 might
exist in the work path subdirectory. These files
will remain on your hard disk if a recording does
not process properly. These files can be deleted.
NOTE: Ensure you do not change to a drive which
causes disk space problems with the OS/2 swapper.
Refer to the SWAPPATH statement in your CONFIG.SYS
file to understand which drive the OS/2 swapper
is using.
If you experience difficulty recording real-time
with the Monitor on, turn the Monitor off and try
again.
When recording video, avoid running other
applications. If you run other applications, the
recorder might not be able to establish all frames
correctly resulting in poor playback quality.
Also, do not attempt to play back video while
recording.
FRAME-STEP RECORDING
Consult the on-line help in the Video IN Recorder for
information on frame-step recording. Look in the
help index for "frame step recording".
BITMAP CAPTURE
To capture a bitmap of a marked region in the
monitor window:
1. Mark the region.
You should see a dotted rectangle around the
marked region. For more information, refer to
the on-line help in the Video IN Recorder
(search for "Bit map Capture" or "Marquee
selection technique").
2. Select Options.
3. Select Record Setup.
4. Select either Real Time of Frame Step.
A settings notebook is displayed.
5. Close the notebook window.
6. Select Bitmap Capture.
7. Select Capture now.
Note the following regarding capturing bitmaps:
* If you mark a region, capture it as a bitmap,
then mark another region and perform the capture,
the results of the second attempt may not be
what you expected. To ensure that you obtain the
desired results, do the following:
1. Capture the first desired region.
2. Reset the data to be captured to be the full image
by clicking on the monitor window.
3. Capture the full image as a bitmap (this can
be discarded).
4. Select the second desired region, and capture it.
* Unexpected results may also occur if you alter the
monitor window to a size other than half size, normal,
or double size, then mark a region to be captured.
The recommended method to achieve the desired result is
to do the following:
1. Ensure the monitor window is set to half size, normal
size, or double size.
2. Select the desired region in the monitor window to be
captured.
3. Alter the monitor window's size as desired.
VIDEO EDITING
If you cut the entire movie from the movie file
while editing, Video IN might not be able to
establish the correct start and end points in the
file. To work with an empty file:
1. Select File.
2. Select New.
MONITOR SIZE
During recording or while cued for input, the
monitor window size is set to match the size
of the movie. Neither you nor the application
program can size the monitor window when
recording or cued for input.
DIGITAL VIDEO PLAYBACK CONSIDERATIONS
_____________________________________
The picture quality and performance of the
playback of digital video (.AVI) files is highly
dependent on the machine configuration and
capabilities. Video clips will play more smoothly
on machines with faster processors, and the
quality of the video picture is better with SVGA,
XGA* or XGA-2* video adapters. Machine
configurations which fall below the performance
requirements of digital video might exhibit any of
the following losses in presentation quality:
o Loss of smoothness in video playback
o Picture clarity limited to 16 colors on VGA
displays
o In extreme cases, loss of the audio
soundtrack
Ultimotion video clips can be played on 16-color
VGA systems, however, the image quality will not
be as good compared to higher resolution systems.
Note: Indeo does not support 16-color modes for
playback.
256 or 64K color display modes are recommended
for the best image quality.
The minimum memory requirement for playback of
movie files is 4MB. However, 8-12MB is
recommended for better performance.
If you are playing more than one movie clip at a
time, you may receive an error message "Error
Allocating Memory from Heap." If this happens,
add the /H parameter to the following statement in
your CONFIG.SYS file, as follows:
DEVICE=d:\MMOS2\SSMDD.SYS /H:nn
where "d" is the drive on which you installed
MMPM/2, and nn is a number from 32 to 256. The
default is 32. For best results, set nn = 32 x
(the number of movie clips being played). For
example, if you plan on regularly viewing 2 clips
at a time, set nn to 64 (32 x 2).
Note: This modification can also resolve a "Not
currently in PM session" message.
To maximize a digital video playback window and
remove the surrounding bezel, select the video
window and press Shift+F6. Press Shift+F6 again
to restore the video playback window.
VIDEODISC SUPPORT
_________________
Video IN provides videodisc support for Pioneer*
laserdisc models LD-V4200, LD-V4300D, LD-V4400,
and LD-V8000.
To install Video IN support, select the "Videodisc"
feature during Video IN installation.
Videodiscs require extra time to process commands.
If you receive an application error message after
issuing a videodisc command, try again.
INDEO DIGITAL VIDEO SUPPORT
___________________________

KNOWN LIMITATIONS
_________________
o The Image Adapter/A adapter cannot coexist
with an XGA adapter. You must remove the XGA
adapter if you want to use the Image
Adapter/A. Also, the Image Adapter/A does not
support the fast screen update modes supported
by SVGA and XGA.
o After selecting a movie size of 320x240 for
the destination movie size, the monitor window
is updated at a rate of 1 frame per second
during recording.
o Odd zoom settings are automatically adjusted
to the nearest even setting.
o If you are using a Video Blaster capture
adapter, 15MB of memory or less is required.
o If you experience problems with the Recorder
application, you can reset the Recorder
defaults by erasing the SWVR.INI file in the
\MMOS2 subdirectory. You will lose all of
your Recorder customized settings.
o If recorded sound is "scratchy," vary the
audio input level on the audio page in the
record setup notebook.
o When playing back software motion video on a
system with a capture adapter that provides
video overlay (for example, Video Blaster) and
the monitor is on, the video might not display
correctly. To correct the problem, do not use
the monitor while playing back video.
o Mouse control might be lost when the monitor
or movies run in applications that modify the
pointer (for example, changing the pointer to
the clock symbol).
o The Video Monitor window does not work
properly in all situations with display
adapters that do not support direct output
(for example, VGA and 8514A). Clicking on the
monitor window might enable the monitor to
work in these configurations.
o The Win/TV Celebrity* and Win/TV Cinema* adapters
are currently not supported. Contact IBM
for more information on support of these
adapters.
o After you have edited a video, video playback
might be erratic and out of synchronization with
the audio prior to saving the file. If you want
to check the final output without overwriting the
original file, you should save the edited video
with a different file name.
o If audio synchronization adjustment is required
after recording, you should adjust the audio
synchronization and save the file prior to any
additional editing.
o If you mark a range that is less than one second,
you cannot play the segment.
o You cannot perform editing functions, such as
paste, on an empty file. You must select an
existing file before a paste can be performed.
