Is it possible to create functionality such that when someone uploads a video to my website, the system encrypts it and other people can't watch it even if they download it.
They would then require a private key to watch the video online.

What you are describing sounds very difficult.
It would be easier to force people to watch it online and simply limit access to the web page via authentication.

gpg does a job like this. You can access the command from within your favorite language, Zend has a tutorial for accessing gpg in PHP.
But wouldn't it be more convenient for your users if they could watch the videos online? Then you would only need to control access to your page with a simple login system.
