Troubleshooting
No video image
If you have no video display (a black video window):
•
Make sure that the camera is connected and turned on.
•
Select the right video input. Use Configure to see all three
video inputs.
•
No video in NetMeeting: you installed NetMeeting before
installing the Videum software. Deinstall NetMeeting, delete
the NetMeeting directory, reboot, and reinstall NetMeeting.
Scrambled video
If your video display is scrambled or the Video Control Panel
shows video but not your application:
•
Verify the NTSC/PAL setting (in Europe: select PAL)
•
Verify that the video format is compatible with your appli-
cation.
•
Try uncompressed capture (YUY2 or RGBT).
Speckled or grainy video
Your display is set to 256 colors or less. Set it to 16-bit or 24-bit
color.
Video capture does not work
For best performance set the compression to WNV1. Capture is
slow at the first time, because the buffers and DLLs need to be
loaded. Poor capture performance: defragment your hard disk
or select a smaller image size. You should pre-allocate a bigger
capture file using the
Video-property
dialog in Videum Capture.
No audio
Multiple sound cards are supported in parallel. The Videum AV
and the VideumCam AV integrate an audio in and out device,
a second sound card in addition to the sound card, which may
already be installed.
