IM NOT SURE IF THIS HAS BEEN ADDRESSED ,but its a bit of a bummer that youtube automatically  gives you only 3 choices (usually lousy) for which image will be the cover picture for your video.PLEASE  make it better here . my pics that appear on my ANY VIDEO CONVERTOR  are ten times cooler and really make the video that much better .
sometimes(like my last one) it selected an actual frame that is in transition ,showing two blurry pics on top of eachother .this is hardly an option .please make it that we select our own covers from the choices we give ourselves ,in that we retain artist disgression here !the opening frame of my last video would be an obvious choice,not offered.

sorry if this was already fixxed (im a bit slow) LOVE YOU TUBE ANYWAY! Bryan Eddy
over 106 videos of my own songs and a few covers!
