Premiere Pro "Quit Unexpectedly" during export

Question

Hello,I've tried to export my sequence multiple times using both premiere pro and media encoder. Each time I tried to export, the applications would quit unexpectedly. For the record, I have exported the sequence many times using Vimeo 720 preset. Macbook Pro (15 inch, mid 2010)2.66 GHz Intel Core i78GB RAMGraphics NVIDIA GeForce GT 330M 512 MB500 GB Solid State Drive (Samsung) - 50GB free SpaceSource footage/project on a 1TB external drive via USBAdobe Premiere Pro CC 2015.3Adobe Media Encoder CC 2015.3Sequence: 1920x1080 - 23.976 fps - Progressive - 48000 Hz, StereoSequence Duration: 3 minutes - 8 seconds - 6 framesSource Footage: mostly 4K MPEG footage from the Sony A7R ii camera. Some 1080p MPEGWorkflow: Edited using 720p Proxy files. Reconnected all the HQ/4K files. Downscaled to fit 1920x1080. Then color graded and added some effects. Exported in 720 to test out the color grade. Made changes. Now I want to export a final version to be uploaded to YouTube and Vimeo. Effects used: All clips have Lumetri color grade. Some have a simple magic bullet looks. Some Denoiser II. A few clips I used Twixtor for Slow Motion. Export Settings: H.264 - YouTube 1080p HD preset Estimated  Export Time: approx. 5 hours. (for a 3min video??? this seems unreal.)I have been closing all other apps during export and disconnecting from internet. Keeping my laptop from sleeping by using Caffeine App. Still, after a few hours the application closes with message "Premiere Pro (or Media Encoder) quit unexpectedly. I can't say at what point the export quit. What am I doing wrong??I am aware there is an update for the apps, but I'm afraid that updating will screw everything up.

I just successfully exported a h.264 - Youtube HD 720 version.... why will that work and not h.264 1080??Through a series of rendering experiments, I figured out that one of the clips seemed to cause the crash. Every time the render or export got to the point of that clip, it crashed. I deleted the clip from the timeline, and resourced it... Just finished exporting a 1080 Youtube version successfully. Still strange that I was able to export 720 with the corrupted clip. The export still took about 3 hours but I do think that is due to my machine's limitations and all the heavy effects such as Twixtor slow motion, Denoisers, Color grades etc.

Your problem is probably caused by your USB 2.0 port not being able to support reading you data fast enough, Especially if you drive is quite full. USB 3.0 is quite capable of doing what you are asking for but USB 2.0 that your computer has is hopeless especially when you start throwing 4K media at it.

Also your down-scaling will not use your GT330M as it only has 512 MB of Video RAM and Adobe CUDA requires a minimum of 1GB.
