I'd imagine they have some sort of system similar to .dems.
The game records NPC movements and positions, and then you can recreate the same scene in-game and record footage from specific camera angles.
So:
A developer plays the game, fights a dragon, kills the dragon (albiet, does this all ina somewhat cinematic way) then they go back and load up the .dem (or whatever the file type is) and they go and position cameras to record what just happened. If you've played GTAIV on the PC, they have system similar to this for the in-game video editor.
