Hi, I am working on Premier Pro of a windows system. I have raw footage from a sony A7 shot at 1080 at 25 frames per second. When I am trying to edit it and output, it is coming out at a much smaller size and the quality is grainy, nearer 640. I have tried to chnage it in the output but has not worked.
How can I keep the file size the same as when I input it?
