This setting scales down the resolution of a video’s layers in each dimension by the given value before sending. For example, setting the value to 2.0 scales each dimension by a factor of 2, sending a video a quarter of its size. The value must be greater than or equal to 1.0 (the default). The default value applies no scaling.
