Ignore this setting unless your downstream workflow requires that you specify it explicitly. Otherwise, we
recommend that you adjust the softness of your output by using a lower value for the setting Sharpness or by
enabling a noise reducer filter. The Softness setting specifies the quantization matrices that the encoder uses.
Keep the default value, 0, for flat quantization. Choose the value 1 or 16 to use the default JVT softening
quantization matricies from the H.264 specification. Choose a value from 17 to 128 to use planar interpolation.
Increasing values from 17 to 128 result in increasing reduction of high-frequency data. The value 128 results in
the softest video.
