This doesn’t answer your question exactly but once you do edit in 4k and render in 4k, you really can’t do much with that I know of except upload it to YouTube or put the file on a memory stick and use it that way on a 4K television. You can’t make a BluRay in 4K. So although I love shooting in 4K, I haven’t found it of much use except the ability to zoom in and still keep HD resolution.
