This is a list of cinematic cutscenes in Halo 3. Courtesy of Cody Miller, these cutscenes are available for download in 1280x720p High Definition and H.264, and have been re-encoded in Standard Definition as well. Both are offered in WMV and MOV flavors. Special thanks to Cody Miller for the contribution. For the sake of bandwidth, the files are being doled out slowly and are being distributed via a load balancing script between the 4 hosting locations. You can find these downloads here, at HBO.
