I believe I suggested "-vcodec mpeg2video -mbd 2 -qscale 2" 
and I didn't change my opinion;-)

ffv1 is lossless, mpeg2video is not and x264 is not 
lossless unless you tell it to be.

Both regarding quality and filesize, I would not suggest 
a lossless encoding from your low-quality source, but a 
high-quality lossy encoding.

(x264 of course allows smaller filesizes than mpeg2video 
for the same quality, so you can safely choose it instead.)
