ratecontrol method (from INT_MIN to INT_MAX) (default 0) QP factor between P- and B-frames (from -FLT_MAX to FLT_MAX) (default 1.25) set maximum number of B-frames between non-B-frames (from -1 to INT_MAX) (default 0) maximum difference between the quantizer scales (VBR) (from INT_MIN to INT_MAX) (default 3) maximum video quantizer scale (VBR) (from -1 to 1024) (default 31) minimum video quantizer scale (VBR) (from -1 to 69) (default 2) video quantizer scale blur (VBR) (from -1 to FLT_MAX) (default 0.5) Recommended range for default rc_eq: 0.0-1.0 (from -FLT_MAX to FLT_MAX) (default 0.5) frame_size E…A… (from 0 to INT_MAX) (default 0) cutoff E…A… set cutoff bandwidth (from INT_MIN to INT_MAX) (default 0) ac ED.A… set number of audio channels (from 0 to INT_MAX) (default 0) ar ED.A… set audio sampling rate (in Hz) (from 0 to INT_MAX) (default 0) set the group of picture (GOP) size (from INT_MIN to INT_MAX) (default 12) diamond motion estimation (alias for EPZS) esa motion estimation (alias for full)ĭia E.V…. full motion estimation (slowest)Įsa E.V…. zero motion estimation (fastest)įull E.V…. set motion estimation method (from INT_MIN to INT_MAX) (default epzs) H.263 advanced intra coding / MPEG-4 AC prediction use only bitexact functions (except (I)DCT)Īic E.V…. Global_header E.VA… place global headers in extradata instead of every keyframeīitexact ED.VAS. Input bitstream might be randomly truncated error variables will be set during encoding use four motion vectors per macroblock (MPEG-4) allow decoders to produce unaligned output Lowering tolerance too much has an adverse effect on quality. This is not related to minimum/maximum bitrate. In 1-pass mode, bitrate tolerance specifies how far ratecontrol is willing to deviate from the target average bitrate value. ab E…A… set bitrate (in bits/s) (from 0 to INT_MAX) (default 128000) b E.VA… set bitrate (in bits/s) (from 0 to I64_MAX) (default 200000)
