Spatial resampling down watermark, percentage of target data buffer. (recommended value : number of real cores - 1) Number of threads to use for encoding, can't be 0 with VP8 At the moment this parameter is interpreted as follows (1 = 1 coefficient partition, 2 = 2 partitions, 4 = 4 partitions, 8 = 8 partitions)ġ,2,4,8: recommended 1 for small images, 4 or 8 for HD Strength of the temporal filter used in altrefīackward (Backward Blur), forward (Forward Blur), centered (Center Blur) ĭirects the encoder to split the coefficient encoding across multiple data partitions that can be encoded independently. Number of frames to look ahead for when encoding, 0 no limit (valid values -min-q to 63, recommended value 50-63)įloat 0 - 1, 0 = CBR, 1 = VBR, (default 0.5)Įnable use of alternate reference frames (2-pass only) (valid values 0-63, recommended value 0-4) Minimal bitrate allowed in vbr/2pass mode
Number of bits which should be loaded into the rc buffer before decoding starts
