* Supported color formats: [[YV12]]

=== Required Plugins ===
Latest version of the following plugins are recommended unless stated otherwise.<br>
*<strike>[[aWarpSharp]]</strike>
*[[aWarpSharp2]] - recommended drop-in replacement for aWarpSharp.
*[[MaskTools2]]

== [[Script variables|Syntax and Parameters]] ==
Defaults are intended for strong sharpening on 2x upscaled material. For normal sharpening, set de to 0.02, str to 3 and cstr to 0.75 and go from there. The failure modes are as graceful as I can reasonably get them, considering the strength of the sharpening required. Also, the degree of sharpening that can be "gotten away with" varies pretty wildly by source.
