Transparent and black video - what's the point now?
A question I couldn't answer to one of my colleagues - what's the point of black video and transparent video now in Premiere Pro v.25?

The point is that in versions like 23.x there still were the effects that now have been removed like grid, circle, ellipse, checkerboard that worked some on the transparent video and some on the black one. So what is the point in having those?
The black video: to create cinematic black bars? There's color matte and EG-layers for that. To apply an effect that demands a black background like Lens flare? You can apply it to your video layer directly (and it doesn't load your system more than when you apply it on a black video - I checked it). To make parts of the video appear black? You can cut parts of the video or apply the Color matte.
The transparent video: to create some kind of a timer or apply effects that need transparency? There's the adjustment layer for that. To apply paint bucket? Well there's none anymore.
So what's the point in them now?
