I want to be able to watch myself in the theater in halo 2 classic clips of ect but halo 2 classic doesnt have a mode for it or it doesn’t save no clips 
343 will you please add it & people please support this i really want it and need it i love watching my gameplay!.
Halo 2 never had support for theatre so this is something that would need to be built up from scratch. As nice as it may be I don’t imagine that’s something that 343 are going to want to devote resources to, the game is over 10 years old now.
You can always broadcast to twitch to save to gameplay, use Xbox DVR or use a capture card if you have one
