Keep the default value, Enabled, to adjust quantization within each frame based on spatial variation of content
complexity. When you enable this feature, the encoder uses fewer bits on areas that can sustain more distortion
with no noticeable visual degradation and uses more bits on areas where any small distortion will be noticeable.
For example, complex textured blocks are encoded with fewer bits and smooth textured blocks are encoded with more
bits. Enabling this feature will almost always improve your video quality. Note, though, that this feature doesn't
take into account where the viewer's attention is likely to be. If viewers are likely to be focusing their
attention on a part of the screen with a lot of complex texture, you might choose to disable this feature. Related
setting: When you enable spatial adaptive quantization, set the value for Adaptive quantization depending on your
content. For homogeneous content, such as cartoons and video games, set it to Low. For content with a wider
variety of textures, set it to High or Higher.
