Hints and Tips If you use the Video Capture driver in Windows NT 4.0, consider the following: - Windows NT color depth changes affect the captured data (preview, overlay). Close the video capture application before changing color depth, and then restart the application. - As a client of the ThinkPad Power Management Port driver, the Video Capture driver has power management support. You must have first installed the ThinkPad Configuration program, however. Otherwise, the driver will not function properly when the hardware changes power states. If the captured image does not appear properly, restart the capture application. - Before running a capture application that uses this driver, close any application the uses the IBM MPEG-2 driver (for example, Media Player). Also if a capture application is running, do not attempt to start an application that uses the IBM MPEG-2 driver, or any other application that uses the capture driver. - For preview mode, you can select image dimensions based on the available space in video memory. For overlay mode, you can choose from all sizes (40×30 to 640×480). Note the following when you use the VIDECAP32.EXE Video Capture application: - Size the capture display window and set a capture format so that the scrollbars are visible. Set the scrollbars to any position other than the top on the vertical scrollbar and left on the horizontal. Then resize the display window or change the capture format so that scrollbars are no longer visible. The captured image now appears split either vertically or horizontally, because VIDCAP32.EXE continues to inform the driver about the scrollbar settings, even though the scrollbars are no longer visible. To fix this, resize the display window or change the capture form so that the scrollbars are visible again, and then reset the scrollbars. - Select a size for overlay greater than the maximum supported for preview. The driver displays a dialog box informing you that the size selected should not be used for preview. If you change to preview mode with the 122 IBM ThinkPad 770X User's Reference

Hints and Tips
If you use the Video Capture driver in Windows NT 4.0, consider
the following:
–
Windows NT color depth changes affect the captured data
(preview, overlay).
Close the video capture application
before changing color depth, and then restart the application.
–
As a client of the ThinkPad Power Management Port driver,
the Video Capture driver has power management support.
You must have first installed the ThinkPad Configuration
program, however.
Otherwise, the driver will not function
properly when the hardware changes power states.
If the
captured image does not appear properly, restart the capture
application.
–
Before running a capture application that uses this driver,
close any application the uses the IBM MPEG-2 driver (for
example, Media Player).
Also if a capture application is
running, do not attempt to start an application that uses the
IBM MPEG-2 driver, or any other application that uses the
capture driver.
–
For preview mode, you can select image dimensions based
on the available space in video memory.
For overlay mode,
you can choose from all sizes (40
×
30 to 640
×
480).
Note the
following when you use the VIDECAP32.EXE Video Capture
application:
-
Size the capture display window and set a capture
format so that the scrollbars are visible.
Set the
scrollbars to any position other than the top on the
vertical scrollbar and left on the horizontal.
Then resize
the display window or change the capture format so that
scrollbars are no longer visible.
The captured image
now appears split either vertically or horizontally,
because
VIDCAP32.EXE
continues to inform the driver
about the scrollbar settings, even though the scrollbars
are no longer visible.
To fix this, resize the display
window or change the capture form so that the scrollbars
are visible again, and then reset the scrollbars.
-
Select a size for overlay greater than the maximum
supported for preview.
The driver displays a dialog box
informing you that the size selected should not be used
for preview.
