Membrane.Transcoder.Video.VariableBitrate (Membrane Transcoder plugin v0.4.1)

Copy Markdown View Source

Defines encoder setting for variable bitrate rate control algorithm.

The following fields need to be specified:

  • average_bitrate - Target average bitrate for VBR encoding; the encoder will try to meet this average over the sequence; expressed in bits per second.
  • max_bitrate - Maximum allowed bitrate in VBR encoding; caps peak bitrate to prevent excessive spikes while maintaining average bitrate constraints; expressed in bits per second.
  • virtual_buffer_size - virtual buffer duration for rate control smoothing; larger values increase bitrate stability, smaller values improve responsiveness to scene changes; expressed as Membrane.Time.t(), defaults to 2 seconds.
