There are some different ways you can film in gmod, probably the worst way obviously is with your own camera. Or for a free program but not the best quality, use wegame.com which lets you film in-game. Or you can get fraps for 30 dollars or if you're so illegal, download it using a torrent. I'm not encouraging you to do this but just letting you know, it is there.
