Did you get the Ignite Digi TB50 plates with Lemo adapters? Or no Lemo output? If you got Lemo's, I think they're working on a solution to bypass the Movi's internal DTap's for heavy-draw cameras like the RED. I saw Chris working on a voltage-step down and power distribution box he displayed at Cinegear, and I've seen someone else (Michael Sutton with Kessler?) making a 24-12V step down box you might be able to use to power your camera directly from the TB50's. That would then possibly allow you to run your 7" touchscreen?
