defmodule Membrane.VKVideo.Encoder.VariableBitrate do
  @moduledoc """
  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_ms - virtual buffer duration for rate control smoothing; larger values increase bitrate stability, smaller values improve responsiveness to scene changes; expressed in milliseconds, defaults to 2 seconds.
