The 4k version is way to big. When making a video from mostly stills it is important to remember a single still image has to be processed to 30 frames a second, hence that single image becomes 30 images. The original file for this video came in at 132megs. To get it under the limits I brought that file back into my video software and just added a tiny bit of letterbox to shrink it just a bit. It actually came out larger still, but when converted in PTE, even at high level it came out at 101 megs. The video was made entirely in PTE. Somehow good old PTE has some way of negating all of this and you can watch the same file at 4k and still come under the file limits. The EXE file is always the preferred file. HD1920-1080 video looks fine on smaller screens.
