about

nx_vcodec_msu_ours13.nx -- EXACT RD points for OUR codec at the SHIPPED CHAIN (2026-07-27 field config, exactly what the family runs and what nx_vcodec_layout_gate proves): KEY frames ride vv_enc_rc (skip-thresh qp*188), P frames ride vv_enc_rct9 (lean+MVD-median, deadzone qp*94), emode 673 = rc+sig+part+deblock, rctx[9] = the MVD MV row-plane rct9 REQUIRES. Same OURS line format as ours12 (total/key/ptot/sseY/keySSE/npix; PSNR computed exactly downstream -- no float here). The x264 arm runs externally on the SAME y4m; BD-rate joins the two curves. CIF only. license: ORIGINAL
