Sword of the New World is having a video-making contest to make an official game trailer. The winners will get a set of 12 Constellation Symbols, a set of Ancient Runes (10 each), 1 selected Lv.92 exclusive elite weapon (e.g. Silver Skullic Bracer), and 1 selected character card (e.g. Grandma, ETS, ATP). The videos must be submitted by June 3, 2010. See Explore, Unite, Conquer! for contest details and video requirements.
You can make your own videos with Windows Movie Maker (included in most Windows installations) and FRAPS. See [sGE] Movie Maker Guide for the actual steps to make a GE video.
In case the game client does not offer you the required resolution, you can force the client to load a different resolution in Windows mode. It may be a bit tricky to record a video when you can't see everything on screen, but it is something you might want to test and experiment. See Windows Mode Resolution and Full Quarter Shot.
