As I edited about a 20 minute clip of video, the memory consumption of Premiere Pro CC 2014 on my MacBook Pro (Core i7, 16GB memory, 500GB SSD with 150GB free, Yosemite) grew and grew. Now, when I open the project, Premiere Pro immediate consumes 30GB of memory! Which means that opening my project now takes about 15 minutes (the blank Premiere application appears in about 2 minutes, but the panels do not complete their slow fill-in for another 13 minutes - all the while the cursor is spinning, not allowing me to select anything, and activity Monty tells me that Premiere is unresponsive). Worse still, when I try to export my project, memory usage grows above 60GB, until my system gives up and reports "Your System has run out of application memory". Keep in mind that I been careful to reboot the system, reset PRAM, and run nothing significant except Premiere, Activity Monitor and Finder. I have Optimized for Memory in preferences, and even tried Limiting Memory usage to 8GB (even though this refers to RAM, not VM).
I monitor Premiere steadily gobbling up resources as VM usage and Memory Pressure increase. I understand that the proximal cause of the error message is probably an excessive number of page faults triggered by the massive memory hogging by Premiere. However, the root cause is Premiere using so much memory.
My 1920x1080 project timeline and bin contain .MTS files (from AVCHD footage), .mpg files (converted via ffmpeg from .TOD files), One EPS graphic, Five .PNG graphics from PowerPoint, One Title, and less than 10 audio files extracted for editing in Audition.
When the export begins, Premiere estimates about 1 hour to encode my timeline. After about 35 minutes, Premier has used up over 60GB of VM which causes Yosemite to report an error, and pause the application.
One solution I suppose is to tell Premier to stop buffering so much content. I have a fast SSD with over 100GB remaining at the time of error, and I can live with the export taking an hour longer if some artifacts are left on disk.
Is there a way to tell Premiere to load less into Virtual Memory?
