  • Media Encoder only using 15% CPU, and system slows to cement

    Posted by Brandon Adams on December 7, 2012 at 12:02 am

    Not sure what’s going on, but trying to export from Premiere CS6 to Media Encoder and very basic 640×360 H264 4 minute clips are taking 40 minutes, only using 15-30% CPU (on 2011 Macbook Pro 2.3 core i7), and the system slows to a cement crawl (had to stop it just to type this post). Nothing else is using any CPU and RAM is 25% free.

    I don’t even know where to begin to troubleshoot. Tried restarting is all so far. Any advice would be greatly appreciated.

    It seems there is a problem with the Mercury Playback Engine on my MBP. I turned it off and switched to software only mode, and now CPU is screaming at 750% on export and estimated time is about 8 times faster

    Same thing here, when i check the “Render at maximum depth” box PP takes only 60-70% CPU, but when i uncheck the option, PP uses 100% cpu.
    And from 3h30min(60-70% cpu) drops to 2h(100%) rendering time on a 40min clip.
