One of the things I've always liked about JRiver is the ability to set up for each video, zoom, and shift that are saved every time you start the video. And this is very useful for those who, like me, have a 2.35: 1 format screen and a vpr without lens memory.
Unfortunately, however, this does not work on the image files that remain full screen and I can not reduce them: is there a way to reduce the size, such as the Theater View overscan?
