nuv (-nuvopts)

Nuppel video is based on RTJPEG and LZO. By default frames are first encoded with RTJPEG and then compressed with LZO, but it is possible to disable either or both of the two passes. As a result, you can in fact output raw i420, LZO compressed i420, RTJPEG, or the default LZO com- pressed RTJPEG.
NOTE: The nuvrec documentation contains some advice and examples about the settings to use for the most common TV encodings.


c=<0-20>

chrominance threshold (default: 1)


l=<0-20>

luminance threshold (default: 1)


lzo

Enable LZO compression (default).


nolzo

Disable LZO compression.



q=<3-255>

quality level (default: 255)


raw

Disable RTJPEG encoding.


rtjpeg

Enable RTJPEG encoding (default).
