Video Tearing / Decklink Quad Reference Input Problem
Here is my setup
Mullumin 2 in Sonnet xMac chassis. Contains 2 Decklink Quad cards. (even though I'm only using one)
One Canvas running 4200x720
Using 3 SDI outputs running to a Spyder, then running DVI to led Wall to create 1 single wide screen.
Originally I didn't have the genlock running to the decklink cards, and they were very clearly out of sync. I pulled out a BM mini sync generator, ran it into both cards and into the spyder (although shouldn't be needed on the spyder).
I have tried both 1080i 59.95 and 720p 59.94, just to try other resolutions, and I'm still getting some tearing between the 3 outputs. The sync between the outputs got visibly better after running sync into the cards, but its still not perfect. They roll in and out of sync between the 3 outputs, so at times it looks perfect, but at times it doesn't.
Spent an hour on the phone with black magic, and they don't have a clue (the tech was also dumber than a box of rocks). I'm a decent spyder opp, so I'm fairly certain the problem isn't with the sypder.
Any thoughts? I have show in 4 hours, and kinda desperate to get this perfect.
