The in/out (or zoom metrics) in accumulate_frame_motion_stats() are in effect a % of the blocks that have a motion vector pointing either towards or away from the center. As such they are already normalized in terms of image size and the thresholds against which these are tested should be image size independent. In practice a zoom either in or out is an indicator for a shorter group length so the abs value is more important as a breakout clause. This patch fixes the threshold test. Clips without noticeable zoom show no effect but some with strong zooms such as "station" show a big gain (5-10%). Average psnr-hvs gain on hdres set was 0.292% Change-Id: I4f97a72b0e273e4e844ade15285749c32cd81c1c
