I'm trying to edit some HD footage that I had filmed with my Canon t4i, and messing with some greenscreen effects. However, upon placing my footage (about a minute and a half long clip) onto my timeline, the preview footage (set to 1/4, and it does not allow me to go lower) is just super laggy/skippy, and I did some editing through the lag, despite not being able to see what I was really doing in preview.. and then tried exporting, but the exported video is also skippy and laggy. I've done research and believe I have the proper sequence settings to match the footage, 1080p, 30fps. etc. and watched several videos on YouTube that claim to be solutions to the problem.. so I'm left wondering if it's something I'm doing, or if I simply need to upgrade my CPU/RAM. I'll post my build below this. Anyone with knowledge on the topic, should I stop wasting my time trying to work out a solution within the program, because it's simply my CPU/RAM? Or, should I realistically be able to work with my build, and it's likely something I'm doing.. I'm lost, and I've tried searching for a solution myself, but no luck.
