Comment (by Agustín Dall'Alba):
Thanks. Adding -qmin 1 -qmax 1 does seem to improve things but you can
still clearly see blockiness in the background with the naked eye. I can't
tell the difference with -g 1. There has to be a way for mpeg2video to
deliver better quality than this.
I don't have easy access to another MPEG-2 encoder, but ffmpeg's mpeg4
suffers the same with {{{ -q:v 1 -qmin 1 -qmax 1 }}} while libxvid
preserves the film grain very well with nothing more than {{{ -q:v 1 }}}.
Is there no way to encode MPEG-2 with ffmpeg and keep the film grain
intact in this scene?
Cheers.
