Decklink Extreme SDI Video Flickers
by Jeff Anderson on Apr 27, 2005 at 8:26:53 pm

I am having a problem with the Decklink Extreme SDI output flickering when it is input into our Sony DSR-1500A VTR. I have tried inputing a reference to the 1500A and going without but it makes little difference. Also, I have changed the reference setting from standard to non-standard but there is no change. The analog outputs look great. Do you have any ideas what is causing the flickering?

MB - Supermicro P4SCT+II
CPU - P4 3.4
RAM - 2GB
OS Win XP SP2
Video - Matrox Parhelia with dual LCD monitors
Boot HDD - WD 7200 RPM
Video array - Stripe set of 4 x 250 GB SATA HDD with Promise FastTrak S150 SX4 RAID controller
Video Capture - Decklink Extreme v4.8.1
Video Editor - Adobe Premiere v1.5

I have solved the problem. I had to adjust the sync timing (H-Phase) on the DSR-1500 and the SDI video input no longer flickers.

Hi Jeff,

Thank you for posting both the problem and the solution. That is very useful information for other DSR-1500 users.
