Argh.

I never noticed that my 720x480 (1.5) frames were being squished to 1.33.
All these years.  Maybe I noticed it once upon a time and dismissed it, although
that seems odd.
I think my current problem is related to the difference between 1.78 and 1.5 vs.
1.5 and 1.33.

Setting
   right AspectRatio*x
where
   AspectRatio = 1.78*1.33
seems to working for me.  It might be a little "reverse fisheye-y" when encoded.
(There's a scene where the camera pans under a Christmas tree.  The edges of the
tree (screen left and right) seem to warp closer to the camera than the tree
trunk.)

I'll run 1000 frames 704x480 at (1.78*1.33) and the same frames at 1.78 and see
what I see.

Thanks!

I'm gonna ask over in animations about modern encoders, once I get my renderfarm
program back online. (I would love to do 1080p).
