![]() motion estimation algorithm (from 0 to 2) (default epzs) ratecontrol method (from 0 to 1) (default ffmpeg)įfmpeg E.V. inter quant bias (from INT_MIN to INT_MAX) (default 999999) intra quant bias (from INT_MIN to INT_MAX) (default 999999) maximum Lagrange factor (VBR) (from 0 to INT_MAX) (default 3658) minimum Lagrange factor (VBR) (from 0 to INT_MAX) (default 236) increase the quantizer for macroblocks close to borders (from -FLT_MAX to FLT_MAX) (default 0) ![]() currently useless (from -FLT_MAX to FLT_MAX) (default 1) initial complexity for 1-pass encoding (from -FLT_MAX to FLT_MAX) (default 0) Also the following constants are available: iTex pTex tex mv fCode iCount mcVar var isI isP isB avgQP qComp avgIITex avgPITex avgPPTex avgBPTex avgTex. When computing the expression, besides the standard functions defined in the section 'Expression Evaluation', the following functions are available: bits2qp(bits), qp2bits(qp). experimental quantizer modulation (from INT_MIN to INT_MAX) (default 0) experimental quantizer modulation (from -FLT_MAX to FLT_MAX) (default 0) how to keep quantizer between qmin and qmax (0 = clip, 1 = use differentiable function) (from 0 to 99) (default 0) Simulate errors in the bitstream to test error concealment. single coefficient elimination threshold for chrominance (negative values also consider dc coefficient) (from INT_MIN to INT_MAX) (default 0) single coefficient elimination threshold for luminance (negative values also consider dc coefficient) (from INT_MIN to INT_MAX) (default 0) Use rate distortion optimization for qp selectionĬbp_rd E.V. Flags common for all mpegvideo-based encoders. Supported pixel formats: yuvj420p yuvj422p yuvj444p
