Inc isn't a real filetype.
Trying to DL the page and running it offline doesn't work because it wants to be hosted on a web server, not from your computer.

Unless that's a preview to a bigger game, and you're actually asking for the game, then I think you should just screen record with internal audio, then make a couple minute looping video for each stage.
