Improve consistency of file sizes. File sizes should be fairly consistent within a given bitrate, but file sizes within your program can grow by 3 or more times just by changing the resolution.

Improve consistency of file sizes. File sizes should be fairly consistent within a given bitrate, but file sizes within your program can grow by 3 or more times just by changing the resolution. I realize that a high resolution and a low bitrate will produce subpar output but I still don't like it that sometimes your program completely ignores my specified bitrate. One time I reduced the bitrate and the file size increased without changing any other options.
