Smart Rule for Studio?

How does one setup a smart rule to only have certain studios populate a channel? For example if I just wanted all disney movies on one channel and a channel of just pixar movies? This way whenever they get added in the future they are auto added to these channels due to the smart rule. Thanks!

Studios aren't a piece of metadata that is indexed in the library.

If you want to do something like this, you can use Labels.

Or create collections for Disney and Pixar and add the collection to a VC
