  Playback speed is unstable with MC Color

  Posted by Huang Di on October 24, 2011 at 5:49 pm

  Hi
  i have the MC color and the davinci 8.1 mac.

  if i play back the r3d in 1/4 few mins the play back speed will unstable which is like FF.

  But the playback speed is stability when I reopen the davinci without MC color.

  I try to reinstall all the soft and drivers,but the problem is stay.

  And I notice that the CPU is up to 60%-90% from 50% when the unstable is happen.

  But the speed is stability and the CPU is up to 85% when I play back the same r3d 1/4 with a lot nodes with out MC color .

  Which is the problem ?

  Sorry for my poor English.

  thanks

  Possibly the Mac needs to use more CPU resources to use the MC Color interface, and that your CPU isn’t powerful enough to do 1/4 Res Red debayer and run the MC Color. Try 1/8th Res and see… Also a Red Rocket card would take a lot of the load off the CPU.

  I notice this occasionally when using RED footage, using the CPU to debayer, and drawing a lot of curve shapes in windows… I lose realtime playback not from too much GPU but too much CPU resources…
