In OS X 10.8.5, did clean install….was having banding with a Radeon 5770. Switched to a Geforce GTX 760…still the same banding. But it doesn’t have any banding when played fullscreen/desktop preview. I guess it’s having problems with the scaling. ****ing sucks. Might finally be time to just leave FCP 7 behind for good.

I have the same setup…MC6 and a Multibridge Pro. I’ve only dabbled a bit, as I’m still finishing a feature edit in FCP and want it done before starting up a new project in Avid getting my old Avid chops back. But so far, the only apparent issue is the set lag/latency of about 1-2 frames when playing a 1080p sequence….even with various ‘frame delay’ settings. Apparently it’s inherent to the LCD monitor itself, which in my case is a JVC DT-V20L1U via HDMI. But…the monitor does have a stereo RCA audio in/out, so it might internally adjust the audio to the frame delay, and I can route the audio back into another channel on my audio monitor controller.
Any way you look at it though, there will always be an offset between the computer monitor/timeline and the output monitor, unlike in FCP where you can adjust the output offset to match the two. Working with the Multibridge output on in FCP wasn’t exactly super-smooth or responsive either…not like a Nitris/Mojo with Avid or even a Pinnacle and FCP from some years back. But if the Multibridge with Avid is at least like it was with FCP, I’ll be used to the speed. If it’s even slower…I might have to start looking elsewhere.

What I did with Automatic Duck was actually make sequences in AVID where all the full raw clips in scene bins were laid out back-to-back, then export those sequences individually. Later, I’d open them in FCP, then drag/paste all the clips in those open sequences into their own bin. A pain in the ass, but I had to do it to have full access to raw material for a re-edit on a project that started in AVID.

“I don’t know what Green/green mode is.”
Go down to the buttons at the bottom of the edit timeline that have the shapes of a TV screen. The one on the left toggles between video output qualities….half-green/yellow for lower res and safer/faster playback, full green for full quality, then full green with a ’10’ for full-quality 10-bit. The button on the right of it toggles on and off the external monitor playback. When the quality is on half green/yellow, you’ll see jagged lines and overall a lower quality image, which is what might be going on with you. Click it to toggle, and you should see the picture improve as it changes quality settings.
As for settings…it doesn’t give you a 720p choice? Strange. I use a Multibridge with mine, and I do have that…maybe it doesn’t do it for the Intensity. I guess it’ll be upscaling your project to 1080 on that setting.

Lots of post audio houses ask for a 720p photo-JPEG at around 50-75% quality. I’ve made one for my own use going through a Blackmagic Intensity Pro on my Pro Tools LE system, and it works fine. At lower qualities you’ll notice some resolution/PQ issues obviously compared to a full-quality ProRes…but for sound work it’s fine and the size stays pretty low and plays fine without stutter or skips/issues.

Thanks John. Yeah, I have read through a couple of discussions with AJA users and it seems to vary….some work with a 0 offset, some with other numbers. With FCP and the Blackmagic Multibridge, it was the same on two different computers, 5…and there was no latency when playing video on Media Express.
-
I’m tempted to just install it for my Multibridge Pro…but from the looks of it, the only addition is compatibility with FCPX. As I noted in my thread, as far as latency goes, I see no difference in the Multibridge’s actual performance compared to FCP, except that in FCP the frame offset can compensate for the discrepancy on PCI-e (as well as firewire), whereas M6’s doesn’t.

That in particular would be very nice.

Thanks Lee. Yeah, embedded audio can come from the monitor or even an adapter. It’d be a little less of a pain when I was using a mixer for my audio as I could just put it on another channel and keep it open. These days, I use a JVC MSC-1, so you can only choose one channel at a time. As mentioned before, I’d attribute the latency mostly to the monitor itself…but it doesn’t show any latency when I play a 1080 clip through the Blackmagic Media Express app…so it seems to be happening with FCP and MC. And…the audio is set to always come from the balanced audio outs on my Multibridge (or out of the Intensity Pro on my other computer)…and that’s always in sync with the edit in the app/desktop. So something with FCP and MC is causing a delay in the (in my case) HDMI out, apparently irrespective of the monitor….on both the Multibridge and an Intensity Pro…when neither experience a delay with Media Express.
Again, easy enough to work around with FCP’s frame delay, but not so on MC’s. Does anyone out there that uses or used a Kona or other PCI-e interface with FCP set their frame offset to zero?

Also, when I use the Blackmagic Media Express to just play back 1080p material from a drive as if I was going to tape, there is no noticeable delay on the monitor. So it seems to be more of a case of the Blackmagic somehow having some delay coming out of FCP and Avid.
