.SS nuv (-nuvopts)
Nuppel video is based on rtjpeg and lzo.
By default frames are first encoded with rtjpeg and then compressed with lzo.
But both passes can be enabled or not.
So you can in fact output raw i420, lzo compressed i420, rtjpeg, or the
default lzo compressed rtjpeg.

Note: The nuvrec documentation contains some advice and examples about the
settings to use for the most common TV encodings.
