Re: This is why I love the bbc
We are talking about streaming TV, and the devices used to display such streams. Of course 50Hz is recommended, but the devices don't implement it. So any 50p stream will indeed be a judderfest. And they are.
BBC makes films etc at 25p, so sure, low frame rates are used. Low frame rates don't cause annoying judder as such, it's temporal erros like pulldown/up that causes issues. Film has always been 24p and works just fine in a real projector.
