4.High resolution = higher quality. While it’s okay to record in a standard 4:3 format, 16:9 (widescreen) is not going away anytime soon. If you can record your videos in high definition, do it. 1280×720 pixels is the “HD” resolution that YouTube will host for you. The good news is that you can record in this size without spending much more than a couple hundred dollars these days – it’s quite affordable, and the results should speak for themselves.
