At a behind closed doors session at E3 2007, Bungie gave a comprehensive demo of its video editor. The video player was included in the Halo 3 Beta, but was only capable of saving entire matches. The map editor is just as Bungie promised. You can save as many games as your 360 can hold. You'll also be able to upload clips (you set the in and out points of a match) or an entire firefight to Microsoft's servers for others to enjoy.
