I also have a Blackmagic Multibridge and my previews are NOT realtime when set to ‘accurate’. When set to ‘fast preview’ its almost realtime.
Very annoying on a 8core and such an expensive system!
Strangly, first install of the blackmagic and the first run all went realtime! Just after second reboot its not realtime anymore and hasent been since. Tried all settings.
Is this a Adobe issue or Blackmagic?
One sitenote. I still find it strange there isnt a 1080p25 preset on BMD cards. I’m in a 1080p25 sequence in Aftereffects, so what preset do I choose? 1080p50 or 1080i50?
