i keep dropping frames in premiere pro im running cs5 with windows 7 64 bit, 3ghz core duo. 4gb ddr3 RAM, 1tb of 7200rpm sata drive, the drive is brand new with nothing stored on it but the clips of the video im editing and about 50 pictures. im shooting video with a dslr canon rebel T2I. im also shooting in 1080x720. i have no idea what the problem is??? im new to pc so this is starting to piss me off. my friend edited the same videos on his mac which is way slower than my computer with no problem his specs are 2 ghz intel duo, 1gb ram????
