Video Playback is shifted
Problem:
VCube displays the correct image at the correct TimeCode on the PC monitor preview. But the video output is not
synchronized correctly. A shift of one or more frames appears to be present on the output of the video card.
Solution:
1. Ensure that both reference video input on the synchronization panel of the VCube, and the video card refer-
ence input are referenced to the same genlock, black & burst, or video signal. This is the only way to ensure
precise timing for the video signal.
2. Be sure that the specification of the video display you use, does not feature some latency. All plasma displays
and some LCD displays introduce significant video delay. If this is the case VCube features independent com-
pensation offset for graphic and video cards. Settings > Formats & Sync : Synchronization - TimeCode >
Graphic Card Delay Compensation / Video Card Delay Compensation.
3. It is equally possible you will observe the same delay with the PC preview. To compensate use Settings > For-
mats & Sync : Synchronization - TimeCode > Graphic Card Delay Compensation.
