+AMD AMF VQ Enhancer filter.
+This filter applies AMD AMF VQ Enhancement to the input video.
+
+This filter accepts the following option:
+
+@table @option
+
+@item attenuation
+Set VQ Enhancer strength. Allowed range is from @code{0.02} to @code{0.4}.
+Default is @code{0.1}.
+
+@item engine_type
+Set AMF memory type used by the filter.
+
+Possible values:
+
+@table @samp
+@item dx11
+DirectX 11
+@item dx12
+DirectX 12
+@item vulkan
