I just had a look at this, and it seems there is some massive problem with Reaper image resize quality. I assuming that the fullscreen preview is the same as the full slow render, here is my very quick rough test:

Look at the top of the plane in the Reaper render, it is jagged and really bad looking.

I have a horrible feeling we are seeing Nearest-neighbor interpolation, the lowest quality resize algo. If this is the case I am praying we can get at least Bicubic asap:

Bicubic interpolation yields substantially better results, with only a small increase in computational complexity.
Justin, could you set the record straight on this? I thought FFMPEG used bicubic scaling by default?
