I recorded in game with resolution 1440x900, then I think I published with 720p (1280 x 720). Next time I'll probably record in a different resolution in game, if the quality is really a bother right now.[/b]
the quality is great (well it really should be when you have 6000kbps bitrate on video) but what i actually ment was these

1440x900 is 16x10 and 1280x720 is 16x9, thats what forms these black edges (most programs would stretch the video to its new resolution but obviously yours didnt).
really looking forward to the next vid
