Premiere CS6 not exporting to ME6 Queue

Question

I've had nothing but success with Premiere Pro CS6, but the ability to Queue up videos to Media Encoder CS6 suddenly stopped functioning (nothing happened that I'm aware of). I'm able to Export just fine from Premiere and can add manually to ME, but cannot export to the queue list.
This happens after reboot, with different video files, and when the renderings are deleted or not. MECS6 will open, but just sit there. Any ideas of what would be going on?

Answer 1

To import a sequence into AME with PPRO closed, open an OS file browser and go to the path where your pproj is saved. Drag and drop that file into AME (either onto a preset in the Preset Browser or directly into the Queue). You can also select "Add Premiere Pro Sequence" in the File Menu and then browse to your project. Regardless of which path you go down, AME will bring up dialog that shows you all the sequences within the project.
I expect that importing through one of these workflows will yield the same results as dragging and dropping a sequence from PPRO to AME. All of these methods work directly with the original project file, whereas the normal workflow of exporting from PPRO (File>Export>Media) saves a temporary copy of the sequence at the instance you export.
Note that in our experience, all of these export workflows add the job to AME in a matter of a few seconds, so we did see a need for a progress dialog. Clearly in your case something is significantly bogging down the process. Perhaps project size or complexity, effects & color grading, some I/O bottleneck.... The fact that drag-and-drop is, what, five times faster makes me suspect that an I/O problem (something like a badly fragmented disc where the snapshot of the sequence is being saved) is at least part of the equation, but that doesn't explain why drag-and-drop still takes over a minute.
Can you check RAM and CPU usage before and during export to see if either resource is getting pegged?
Also, what drives do you have your project on and are you encoding to? Are you using a solid state drive? An external drive? Working across a network? Do you have antivirus software running?
Another possible culprit is conforming audio. I'm not sure what the best way is to check if that's happening other than watching your media cache folder to see if new files are being written.
