be corrupted. To fix this, select a valid size using the Video Format dialog. To restore the cursor, drag it to the bottom of the screen. VIDCAP32.EXE assumes that preview and overlay are both supported for the same sizes. So if the application is on overlay mode, and you select preview mode without selecting a valid size, the driver is informed that it should preview to the same size. But since an image of this size cannot be captured in the frame buffer, the captured image looks distorted and the cursor image is also affected. This is also a problem if you use Digital Video Producer. This driver does not provide the YUV422 video codec for preview/capture mode application that needs to use YUV422 video compression codec. Install the YUV422 codec that is available in Windows NT 4.0 CD-ROM. YUV422 codec is available in Drvlib/Capture/I386 directory in the Windows NT 4.0 CD-ROM. Overlay mode is not supported for the following resolution, color depth, and refresh rate combinations: - 1024×768×256 colors, 87 Hz - 1024×768×64K colors, 87 Hz - 1280×1024×256 colors, 87 Hz If you connect your computer to external TV, Video Capture will not work. It works only if the display output location is either the external monitor or the LCD. Do not change the display output location while the Video Capture application is running. Chapter 3.
