SUMMARY
The Super VideoWindows and TV-VideoWindows video capture cards from New Media Graphics must be configured to utilize hardware interrupt 10 to work correctly under Video for Windows. If this interrupt is not selected you will receive the following error message when you attempt to capture video using the VidCap utility.

No frames were captured, confirm that vertical sync interrupts are configured and enabled.



MORE INFORMATION
The following excerpt is from the release notes provided with Video for Windows: ============================================== New Media Graphics Driver

=
=================================

This release includes a video capture driver that works with the Microsoft Video for Windows software.

The Super VideoWindows board is installed through INSTALL.EXE, supplied by New Media Graphics. Once you've run this program another accessory, VCONFIG.EXE, is used to configure and adjust the colors for the board. Use the other supplied accessory, VDEV.EXE, to check the installation.

After you've run these accessories to install the board, use the Control Panel Drivers option to install the SuperVideo Windows video capture driver included on this disk. Choose the Add button and select Unlisted Or Updated Driver to install the correct driver. There is one driver compatible with all versions of Super VideoWindows and TV-VideoWindows.

Once the driver is installed, you may use the AVI capture program VidCap to capture frames, sequences of frames, or capture video in real time.

If you have an earlier SVW-ISA card, you may not be able to use the real- time video capture feature of the VidCap program. See below.

After installation and setup is complete, you may want to check to see that NMGSVW.DLL and NMGSVW.INI are both in your WINDOWS\SYSTEM directory.

Note: The Super VideoWindows board uses INT 10 only. If you want to change the I/O port address for the card, you must use the Control Panel Driver's option, the VCONFIG.EXE utility, and then restart the machine.

If you have any problems or questions about the SVW capture driver, please call the New Media Graphics technical support department at (508) 663-0666.

All Cards -

In order to use the AVI Video Sequence capture feature, you must enable the interrupt jumper on the board. The number and location of the jumper varies from board to board. Refer to the board specific directions below. Use an unused jumper block from the I/O address selection jumper to enable the interrupt.

SVW-ISA, SVW-CM ---

The interrupt jumper is labeled JP18 and is located above and to the left of the edge fingers on the bottom of the card, when looking at the top of the board.

Note: Some earlier revisions of the Super VideoWindows board may not support interrupts. These boards are marked REV 2A, REV 2B, or REV 2E. They can capture single frames, but cannot capture a sequence of frames in real time.

SVW SL, TV-VideoWindows ---

The interrupt jumper is labeled JP13, and is located above the shorter row of the card edge fingers when looking at the top of the board.
