That's certainly not normal.
Unfortunately, I don't have any ideas about a cause, which means no ideas about a solution either.
Does this happen with all projects? New projects? Are you using the Warp Stabilizer effect at all? Have you tried trashing preferences?
It does happen with all projects. I have tried a previous project as well as starting two different new projects before and after reinstalling.
Just trashed preferences and opened a clip. On starting playback, my physical memory jumped from 29% to 89% and kept rising like yesterday.
My machine has 8 gigs of RAM which should be more than enough to handle premiere and has been for the last five months.
I'm not too concerned about how much is being used. PP will use what it needs and may not let go until you close it.
The issue is with the crashing.
So...do these new projects crash as well?
Yes, the new projects crash the exact same as the existing ones. The problem is that it is crashing BECAUSE it is using my entire physical memory. Again, I have not had this problem before now and I have not had any hardware changes or anything that should affect it.
The only idea I have left is to start a new user account. Make is Admin, not a guest.
If that doesn't work, we may be down to a reinstall of Windows.
Oddly enough, I recorded some new footage directly to my desktop instead of to the external harddrive where i was recording it to before. Something must have gotten messed up between transfers. Thanks for the help.
