If I want to make my own little legitimate music TV on the Internet, what about the purchase of video clips, is it open content or paid?

Question

Audio

Hello.
Let's say I found a technical way to permanently broadcast video clips to the Internet.
But I want it all to be legal. What about the video clips themselves, are they public content that you can just use, or do you need to buy the rights from someone?
Is it possible to use content under a Creative Commons license.

Answer 1

Your clips - publicly available
not made by you - need to be bought
