As AI continues to improve, it's getting harder to tell when videos are real, or generated by a computer.

Tech giant Meta says it wants to help clear up the confusion with a new tool that basically adds an invisible watermark to AI-generated videos.

You can't actually see these watermarks, it's a digital signature that's added on to AI-videos and is designed to be hard to remove.

So, will this make it easier for regular people to tell if a video is real or fake?

Listen to what AI consultant Raj Shroff has to say in this week's Tech Tuesday.

You'll also hear about a new 'Play Something' button on YouTube that basically decides what you watch next, and how this could affect how we browse content.
