Hoping someone can help....I am creating a video exhibit and the screens (2) will be one over one (46" screens) in portrait orientation (like a popsicle stick) 4k resolution. Pixel ratio obviously will be 3840x2160. I cannot find a codec which will allow me to render video in portrait (3840 vertical) orientation...with the exception of the gopro cineform codec which is only available for quicktime. I rendered out just five minutes, of what will be about a 50 min video, and it was over 37GB. The end product's file size would pretty much be unmanageable on the player I will be using. Anyone have a suggestions with respect to an alternate codec I would be able to use that is not quicktime?
