Hi,
if we consider that this tutorial:
is the only proper way how to make the right cinema aspect ratio working in the righ way in all screens (without just adding black bars) I have to say that it does not work in VP as you can see on the pic. I set the project the same way as the guy did in Premiere (3840 x 1574) but there are strange strips on left and riht side. What do you think?
