then you know for sure that CNN released it.
Why not link to the original CNN source then, if you want to be trusted? You’d have to do that anyways if you want to use the CNN footage in your own video.
I don’t think people who care about the validity of a news video will be helped much with this, and people who don’t care about the truth can easily ignore it too.
As a news organisation they should have their own due diligence about sources etc
But what if they can’t anymore? News orgs don’t only show video that they recorded. They have videos from freelance reporters, people who were at an event, government orgs, other news orgs in other countries…
How would that work? Why would you have any reason to trust me in this chain?
