  "message": "Move all of LBD Daala TX to up-4, down-1 shift\n\nNow that tran_low_t is assumed to be 32 bit when Daala TX is active,\nthere\u0027s no reason for multi-stage shifting to fit coefficients into 16\nbits for the inter-tranform transpose matrix. Go to a consistent up by\nfour, down by one shifting scheme for all TX block sizes.\n\n(Note this is for the current AV1 coefficient scaling scheme with\nav1_get_tx_scale and deeper coefficients for higher bitdepth input.\nDaala TX is moving to the long-intended constant-coefficient-depth in\nupcoming patches).\n\nsubset 1:\nmonty-4-1-baseline-s1@2017-11-11T05:57:15.857Z -\u003e\n monty-4-1-test-s1@2017-11-11T05:57:52.983Z\n\n   PSNR | PSNR Cb | PSNR Cr | PSNR HVS |   SSIM | MS SSIM | CIEDE 2000\n-0.0117 | -0.0246 |  0.0530 |   0.0238 | 0.0254 |  0.0447 |    -0.0442\n\nChange-Id: I2214e94ac822542c504d472276723277ed350abf\n",
