[x264-devel] [PATCH]adaptive lowpass

[Gabriel Bouvigne]

This patch adds a --lowpass option that does an adaptive lowpass of 
input, according to Qp level.
It's a bit similar to the --nr option, except it really does a lowpass 
(with a transition band) instead of a noise-gate.

It will increase SSIM by a very tiny amount, but will reduce PSNR 
significantly.
When you are into the high Qp range (which you should avoid, btw), it 
helps reducing a bit the big flat quantized areas.


Regards,
