This video is 1080p at full screen if you have a big enough display (make sure you have HD selected); you really need to see it at this resolution to appreciate the differences properly.
A side by side comaprison of a 4-perf Anamorphic standard 35mm negative against a 2-perf Spherical super 35mm negative. Explanations of the difference in resolution are explained in the previous post.
NB one can really appreciate the differences in a theatre projection; i’m afraid H264 doesn’t really do it justice.
