In particular, use last frame MV data for 1080p resolution that was NOT used before. Only exception are: - screen content at 1080p+ resolution will use QTR_ONLY MV precision mode - 4k or larger: will also use QTR_ONLY MV precision mode In CTC, affects A2 and B1 sets only. - RA CTC 33 frames, speed 4: ``` +---------+--------+----------+ | Summary | YUV | Enc-time | +---------+--------+----------+ | A2 | -0.11% | 98.35% | | B1 | 0.01% | 97.89% | +---------+--------+----------+ ``` - RA CTC 33 frames, speed 1: ``` +---------+--------+----------+ | Summary | YUV | Enc-time | +---------+--------+----------+ | A2 | -0.03% | 98.61% | | B1 | 0.01% | 99.72% | +---------+--------+----------+ ``` STATS_CHANGED
