From d84bf53f607982f002f1900e4c5894ba9b470770 Mon Sep 17 00:00:00 2001 From: Marco Paniconi Date: Thu, 21 Feb 2019 19:32:07 -0800 Subject: [PATCH] vp9-rtc: Adjust thresholds for noise estimation. Lower the frame_motion and consec_zeromv thresholds, this make the noise estimation and denoiser have more effect on noisy clips.
