Few time I will get an error, like I've ran out of computers usable memory during editing 30 minutes to hours in). I have 1 gb of DDR3200 on P4 platform, so I'm in no hurry to upgrade to more memory yet (hoping thats enough), is there a way thats better than hitting Save from time to time to re-cache memory during editing. Alternate way I do is to Save Project and re-save and write over clip as I update..
