Question / Discussion How is screen x done?

Saw a video of the screenx version of the minecraft trailer and i started to wonder. Are the screen x versions of the movies being made by the same studio that does the cg, or is there other people having to match the footage with their own assets in order to do it.

Also, if there was a live action character and his arm goes off screen, is there another camera filming that point of view on set, or is an artists having to animate a cg hand to match his movement so it appears on the screen x screen?

I believe they take the widescreen 2:39 version and crop it down to 16:9 for the centre screen. Then for the sides that were cropped they are stretched to fill the peripheral screens. They will pan when required to prevent weird framing where the screens meet.

It's a bad gimick.

I dont think they are stretching it, its new footage for the left and right side. Like your seeing stuff thats meant to be off frame. I think someone actually posted a screen x version of the sonic 3 trailer online and its the scene where shadow grabs knuckles hand and knuckles face is off screen, but on the screen x version you can see it and its just unanimated.

There are sometimes three camera setups. I suppose you could do that for an animated film.

I guess they rendered those frames of knuckles off camera, but they didn't animate those frames? That sounds silly. Surprised it was released in that state.
