Premiere Pro CC taking FOREVER to export

Made the mistake of running latest update of CC and now exporting basic H264 with YouTube 720p 29.97 settings is taking almost 3x's as long. Have lots of short 3-5 minute videos to turn around today and looking at hours of wasted time. Help

This is a possibility:  You have a or some corrupted footage items in your timeline.  Try exporting between in and out the first half of your sequence.  Then, export the second half.  If there's a substantial difference in export times, the slow export likely contains your problem footage.   Keep reducing the export ranges until you isolate the culprit.  Then, replace it or transcode to another codec.

I've also seen corruption in my Preview files, and media caches.  When I have a "was working fine, but not any more" situation, I do a deep clean.  Trash Pr prefs, trash previews, trash caches.  And if that doesn't work, search and destroy corrupt media.  Final straw: uninstall and reinstall Pr.

Since you're on Mac, you might try Digital Rebellion's Corrupt Clip Finder.  I've been given hundreds of corrupt JPEGs from clients. Converting them to TIF or PNG has allowed me to finish my projects.

Good luck.

Edited to add new info.

Hi minutephysics,

What is the codec for your rendered previews? What is your output codec? Are they the same?

Media Encoder isn't any faster, either. It doesn't matter whether I use software or CUDA accelerated export, either. They are all slow. I'm getting no direct indication that there's an error - just that PP takes far too long to export. Unacceptably long. Rendering times are fine, so there's not a problem with my system there.

Which effects are you using? Any effects with a lot of overhead like Neat? Can you post a screenshot of your export settings dialog box?

Thanks,
Kevin
