  "message": "Free temporal filter strategy from screen content.\n\nTemporal filtering strategy should be free from screen content type. It\nstill need to explore whether temporal filtering should be turned off if\n`allow_screen_content_tools` is true.\n\nNOTE: This CL only affects partial clips from midres and hdres sets.\nSome clips show significant gain while some show severe drop. Even so,\nthe filtering strategy still shouldn\u0027t be conditioned on screen content.\nIn other words, screen content should affect whether to do filtering but\nnot which filtering method to use.\n\nExperimental results:\n\nUnder Speed-4 (two-pass mode):\n                                        avg PSNR   ovr PSNR     SSIM\nsnow_mnt_480p.y4m (midres)                -0.424     -0.515    0.499\nMobisode2_832x480_30.y4m (midres)         -0.719     -1.091   -1.053\nsintel_shot_854x480_24fps.y4m (midres)     0.787      0.473    0.216\ndinner_1080p30.y4m (hdres)                 0.889      0.775    0.382\n\nUnder Speed-1 (two-pass mode):\n                                        avg PSNR   ovr PSNR     SSIM\nsnow_mnt_480p.y4m (midres)                -0.618     -0.641   -0.059\nMobisode2_832x480_30.y4m (midres)         -0.687     -1.108   -1.489\nsintel_shot_854x480_24fps.y4m (midres)     0.902      0.597    0.354\ndinner_1080p30.y4m (hdres)                 1.900      1.179    0.546\n\nSTATS_CHANGED\n\nChange-Id: I383831adf5e1517e6db78eacd30f94425065ddcf\n",
