Video sync drifts
Do people here experience video sync drift even though their system is genlocked?
I am currently using a BM UltraStudio Express video card feeding HDMI signal to a laser projector and after a hour or so of editing the sync is noticeably off. Restarting PT or the projector, or disconnect/reconnect the HDMI seems to return things to normal. I am starting to wonder if the HDMI is the problem as I have tested 3 projectors of the same make and the problem persists.

Re: Video sync drifts
What Decklink driver are you running?
Drivers 11.5 and 11.6 are known to drift. See this table for qualified driver versions: https://avid.secure.force.com/pkb/ar...eo-Peripherals |

Re: Video sync drifts
With 11.4.1 the video engine took an age to launch and then failed! I guess this BM driver version is too old. Reverting back up to 12.1.
