Add On Note: In your reading of how tos and suggested articles posted here or elsewhere, please note the dating of the article as well as the Premiere Elements version mentioned. Premiere Elements 11 does now have 1080p60 and 1080p50 project presets whereas earlier versions did not. Also, note that the direct upload to YouTube from Premiere Elements has had a 15 min (not 10 min) limitation as far back as version 9.0/9.0.1. And you can export 1080p50 and 1080p60 from Premiere Elements 11 with customization of certain existing presets. More information on that and more if needed.
