Captain Disillusion is an Internet show by Alan Melikdjanian who hosts using his alter ego, Captain Disillusion. The show's began by debunking viral video hoaxes where Captain Disillusion taked a modified video which is being passed off as genuine, shows what video editing techniques were probably used to modify the video, and then frequently creates a similar video himself using those techniques. The theme of the show seems to have morphed into understanding how visual special effects work.
As a skeptic, I feel a duty to point out hoaxes when my friends and family share them. Researching their videos they post online often leads me back to the Captain Disillusion channel, which was how I became a fan many years ago. To this day, I still find myself linking to his past videos when a well-meaning friend is duped by an online video hoax.
