From a5397dbaf13c87516bbf404dea35fe49bfe805e3 Mon Sep 17 00:00:00 2001 From: Yaowu Xu Date: Wed, 3 Nov 2010 12:56:31 -0700 Subject: [PATCH] Increase the resolution of default timebase The old value 1000 was too low, which caused the effective duration and frame rate calculation to have an 1% error for typical 30 frame/second inputs. Symptom of the issue has been that most 2 pass encodings were undershooting target bit rate by 1% or so for 30 fps input.
