Hi Leif


I assume that this is a consistent problem that happens every day and all day, from the way you describe it across both your main and backup machine. I also guess this is a long running tour as your OS is 10.6.2 with a older version of Catalyst? May be worth running m364 to test and even setting up a 10.6.8 partition on your back up machine to test(keeping the original 10.6.2 partition too) if any of my suggestions below don't work.

What is the input resolution and frame rate that you are ingesting at, and what is the output resolution and frequency. also how many inputs are you running? It may be worth turning off all but one of the inputs in the input panel in the HUD.

From what you have described I would widen your scope of fault finding to pre catalyst. And if you have access to one I would use a image pro with a test pattern with diagonal motion on and plug directly into the phoenix card and see if the tearing is manifesting and then A/B test each point in the signal path, all the way to pre Switcher if necessary. This is no reflection on your racks engineer, but frame grabber cards are quite sensitive to timings that won't always show on a monitor. Places that are common sources of timing issues are aux output cards in the switcher crate, DAs and once in a blue moon matrix outs.

Plan B would be to tweak the programming of the show and loose the top 10px or crop the top of the frame in the inputs in the HUD. Either which way make sure you keep a original version of the show to go back to just incase.
