    Layers intermittently appearing as black during rendering

    Matt Paintin Level 1

      I am using 4K mp4's (3840x2160) that were shot on a Panasonic GH4 Camera and have just started to comp two elements together in AE CS4. One of the layers is a green screen element also shot on the GH4 at 4K.

      The comp itself is at standard HD allowing me to re-rack/ push in with the 4K footage.

      During both playback and rendering the layers will randomly appear as black for one frame and then return to normal on the next frame. Effectively the layers are winking on and off throughout the process.

       

      I suspect that my machine is having memory problems with the 4K footage (even though its an mp4) but I would appreciate any help or preference settings suggestions as a work around. I wouldnt have thought that I'm pushing my workstation too hard. I've certainly have much heavier comps in regular HD and have rendered then without issue.

       

       

      Here is the workstation spec:

       

      2.67 gigahertz Intel Xeon

      Multi-core (4 total)

      Hyper-threaded (8 total)

      6144 GB Memory

       

      I'm pretty paralysed on this project if I cant use the footage I'm shooting.

       

      Thanks.
