From 32c4fdec7862657bc3865ca0f2dd151ee0e45646 Mon Sep 17 00:00:00 2001 From: Paul Wilkins Date: Fri, 21 Mar 2014 16:14:46 +0000 Subject: Experimental change to speed 1 settings. Allow tx search for ARF and GF helps quality but a little slower. Setting subpel_iters_per_step to 1 improves encode speed. Setting sf->mode_skip_start = 10 improves speed. Initial local results suggest overall impact on quality is neutral but encode is up to 15% faster.
