just look things up bro,google anything you don't know about handbrake or anything else. i just messed with settings until i realized that's where i get the best quality...so i'm giving you a shortcut to hours of trial and error...my 640x360 videos almost look as good as the HD video source...the HD videos stay pretty much the same after conversion. If you don't have dedicated graphics,i'd recommend you stay @ 640x360 until you buy a better/higher spec Macbook Pro 15" ...be careful too,the're some 15" with no dedicated Graphics...
