Instructions
Complete a match in "Halo Reach." If you have a hard drive, whatever takes place in the match will be recorded for later viewing. Move and interact characters as you desire, as the "camera" is automatically rolling.
Select the Theater mode from the main menu of "Halo Reach." Choose the video of the recorded match you wish to edit and view.
Load and replay the video to see what you have to work with. Edit the video using the simple controls listed at the bottom of the screen. Play with the 3D video of your match and alter the angles and record at different intervals to get the desired effect.
Upload completed videos to "File Share" so that you and your friends over Xbox Live can view them anytime. You can spend Microsoft Points to have favorites rendered to a high-quality video file for online viewing at Bungie.net.
