So i just got an hd camcorder and was excited to edit hd footage with it on sony vegas pro 10, but it lags a ridiculous amount on sony vegas. My computer isn't THAT bad but im wondering if its good enough. It has Intel celeron processor @ 2.2 ghz and 4gb ram, so i would think at draft half preview it should run ok but it doesn't. I know about shift+b but thats stupid dont even tell me that, its like a 30 sec render and is unrealistic. Any suggestions?
