Ignore this setting unless you need to comply with a specification that requires a specific value. If you don't
have a specification requirement, 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.
