I have just upgraded to Production Prem 5.5 from 5.0 but Premiere does not see the Black Magic Intensity card at least the video side of things. The BM audio IS listed under Prefs audio hardware but is not listed under sequence presets or capture.
Have tried multiple uninstalls reinstalls including deleting registry enteries device drivers etc even reinstalled Premiere. The installs always seem to go fine device drivers installed ok but Premiere refuses to see the BM card for the video so cannot input video unless I use direct DV via the mother board and firwire.
Windows 7 Ultimate.
Worked fine under CS5.
Going way back to the Pinnacle Dv500 I used with Premiere 6x, Premiere & Premiere Pro do not work with ANYTHING other than a plain Firewire card... unless the card vendor provides a device driver to "marry" the card's hardware to Premiere
Your problem is with Black Magic needing a device driver update, not with Premiere Pro
All latest drivers/software used from BM website. It looks as though others are using BM with 5.5 ok.
