Normal flash on the Samsung Series 5 Chromebook is amazing. It will play 720p at full screen almost perfectly (very occasionally it drops a frame - but I mean - once every for minutes). Peper flash on the other hand cannot cope. In this video I play the same Youtube clip with both flash types on my Series 5 recording it with a 1080p Panasonic 3COMS camera so you can really see the difference. PS at one point in the video I say 1080p as though I am referring to the Chromebook not the camera. The Chromebook runs at 720p in this video.
