    AE performance with AJA / Blackmagic video output

    theiceage13 Level 1

      Hi,

       

      is there any way to improve the performance of AE when working with video output? I have an AJA Kona LHe installed on one workstation and a Blackmagic Decklink Studio on a different workstation. I work with 1920x1080 DPX-sequences most of the time. RAM-Preview works fine (means realtime) when I deactivate my video-preview. But with video preview activated I get a frame rate around 15-20 fps.

       

      I know that AE is not supposed to provide a perfect video preview in realtime, but is there any way to improve this a little bit?

       

      Fun facts:

       

      - when turning my quality to half or quarter, the frame rate is even lower (around 10-15 fps)

      - different source material acts different...quicktimes give me realtime sometimes, dpx sequences result in 15-20 fps. I mean - AE is putting the comp into the RAM ("RAM-Preview") - shouldn't it make no difference what source material in my comp is?

       

      Thanks!
