What have I said is actually questionable? 8K is already beyond the limit of what a human can see at any practical viewing distance. Super high end film might beat it in equivalent resolution, but at that point it’s purely academic because you’re eyes can’t see that much detail.

Unless you want to blow up a small portion of the image to poster size… then I am sure IMAX film is better. Just not sure why you would want that.

Meanwhile in framerate you can see a fairly large difference between the two technologies.
