John and All,
Thanks for the information. It helped point to the solution of the mystery.

It turns out that the Multibridge will accept SD info on the IN A and IN B inputs. However, if it senses SD input on both of those inputs it assumes you are sending dual-channel SD and will only allow digitization at 4:4:4:4 rates.

That was the reason my visual was pink and out of sync. I was not sending 2 channel SD, only one channel on 2 different lines. So I was fooling the Multibridge. The cure was to remove the IN B input and poof! the Multibridge understood the signal and gave good output to FCP.

Thanks for everyone’s input, it really helped track down the mystery. Thanks also the Eric at Multibridge for going slow for a newbie. In the process of solving this I’ve found several excellent professional forums that I’ll stay connected to, including this one.

Thanks again, John

HI Guys,
Another think I noticed: the video capture seems to bog down the longer it goes, until it gives me a Dropped Frames error and drops out (within 30 secs). Could that point to a timing error of some sort?

Thanks, John

Hey John,
THanks for the reply.

Not sure what you mean by reference video. I have the capability for bars out of the switch and I’ll check that.

Cable runs from switcher to encoder (blkmgc) are less than 4 feet.

The fact that it did run well last week makes me think there’s a setting wrong somewhere. I wish I could check the Blackmagics functions separate from the switch. I’ll work on that today.

I thought I could check the incoming signal with iMovie but iMovie doesn’t open within camera mode, probably as a function of the 1080i and the signal coming in thru the PCI Express bus instead of Firewire.
