    PlayBack starts and stops after 10 to 15 seconds...


      I can not turn in a project:
      Project Setting
                   Reading and video rendering
                                      Rendering system''Mercury GPU Acceleration Playback Engine''
      The cache is always grayed-down list appears and Software''Mercury''Playback Engine and GPU acceleration does not appear''Mercury''Playback Engine

      Thus, perhaps because of this that the video playback after import starts and stopsafter 10 to 15s. And in After Effects, the reading is very very slow and choppy evenafter rendering.

      What to do please?

      Thank you for your help
