I finally made the switch from standard to HD. I'm editing a 1920 x 1080 project, at 60i. When viewing my footage in the standard browser or canvas setting, this footage looks and plays back fine. But if I enlarge either of these windows to a much bigger size (or output a Quicktime) it doesn't play back real smooth....sort of slow and a bit jerky. "This won't look this way when I burn a disc will it?"
"Could this be because I'm running just 2gb ram, or is this a VRAM issue?"
" I only have 256 mb VRAM and my graphics display is a NVIDEO GFORCE 9400, on an iMac intel, 3.06 Intel Core Duo."
