Sadly the 3D release of Avengers Infinity War did not come with any opened up IMAX scenes so I have used the Russian Open Matte stream, that has more image on the top and bottom compared to the blu-ray, as the main source of this release.
One definate advantage this Open Matte version has over the other Marvel IMAX releases based off the 3D blu-rays is that it does not have the left sidebar changing width from shot to shot.
