I was going through my typical workflow with 1920x1080 footage and while scrubbing through in the preview monitor or playing from the timeline the video would freeze. The playhead and sound would sometimes continue, sometimes not. Sometimes the footage turned to Media Pending. I would save and try to exit, the screen goes white and says not responding. All yesterday I was able to get a few clips into my timeline before this happened. I was restarting the program every 3-5 min. I also tried restarting my computer, clearing my cache, and moving the project to a different location. Today all the footage says Media Pending and the Program monitor remains black when I try to play from my timeline. And of course my project deadline was supposed to be tomorrow.
I am still on CC 2018 because I don't have Windows 10 yet. It seems contained to this project but I'm halfway through it so I don't want to start completely over. I've tried offlining the footage and relinking it but the screen goes white and says Not Responding whenever I try. I've watched my Task Manager while working on Premiere yesterday and the CPU and Memory never got above 60% even when the program froze. And as I was writing this my computer came up with a message that it's low on memory which doesn't make any sense to me.
I think my next step will be to try a different computer, reinstall Premiere on my machine, and maybe move all the footage to a new harddrive. Does anyone have any other suggestions? I'm near my wits end!
