    Insanely slow export in CC

    Me8190

      Hello, I'm pretty new to Premiere Pro CC, and I just finished editing my first video.  I was stunned by how long it says it will take to export the project, and I figure I've got to be doing something wrong because I'd like to think that my computer is pretty powerful.

       

      Here are my computer's specs:

       

      Mac Pro tower Mid 2012 OS X 10.8.5

      3.2 GHz Quad-core intel xeon processor

      32 GB RAM 1066 MHz DDR3 ECC

      GPU ATI Radeon HD 5770 1024 MB

      Three 7200 RPM SATA Disk 1TB Hard Drives

       

      The video is 30 minutes long, 1920x1080 (1.0) 29.97 fps, H.264, 48000 Hz, has a few color correction plugins and contrast adjustments, and it's crazy slow no matter what format I export to. When I try to export to QuickTime with the Preset: HD 1080i 29.97, etc, the estimated file size is 2285 MB and the estimated time remaining to export is over 20 hours. It's basically stuck at 0%. When I try to export to MPEG4 the estimated file size is 73 MB and the estimated time remaining is over 9 hours.

       

      I've been trying to research this stuff for hours now, and I can't seem to figure out what I'm doing wrong.  I've been reading some things about how CC has slowed down exporting in comparison to previous versions of Premiere Pro, but this is ridiculous.  I mean, there's gotta be something I can do, right?  Any help would be greatly appreciated.

          Are you using hardware-accelerated Mercury Playback via OpenCL?  Have you set Maximum Render Quality in the Export Settings?  Software MPE playback is slower than hardware in many cases and if you combine that with MRQ then you can get very long renders.  And if you're not scaling or deinterlacing your video, you may not need MRQ at all.  Your choice of Color Correction plugins can have an effect on render time as well.  If the plugin can't be hardware-accelerated by Pr, then render times can increase significantly compared to the CC tools in Pr that can be accelerated.

           

          Cheers,

          Jeff

            Thanks for your reply Jeff.  I messed around with all those settings you mentioned but had no significant changes in performance.  Then I exported with AME instead of direct export and it was way faster.  It took about an hour and 30 minutes.  Still having slow rendering though, so I'm not really sure what else to do there...

              Hi Me8190,

              In the lower right corner of the Queue panel in Adobe Media Encoder, is the pop up menu set to "Mercury Playback Engine Software Only?" If so, change it to "Mercury Playback Engine Software GPU Acceleration (Open CL)." If you do not see hardware options, see this post for a workaround.

               

              Thanks,

              Kevin
