And DarthBalls1138, thanks for the tip. I remember now having heard of Camtasia sometime ago. Do you know if it compresses the video it records or not?
I still would like to do this thing, since my initial idea was to make a movie out of the cutscenes, gameplay and additional sound elements, rather than just edit the cutscenes together. I'll look into Camtasia for sure, but if anyone else knows of a better way to capture gameplay into video files, please share it. Also, is there possibly a way to get the cutscenes extracted from the game somehow, like getting the source video files instead of capturing them from playing the game?
