{{FilterCat4|External_filters|Plugin_functions|Adjustment_filters|Sharpeners}} 	
Sharpening filter like VirtualDub's WarpSharp. This filter tightens edges in an image by warping the image toward edge boundaries. For additional information take a look at the [http://www.virtualdub.org/blog/pivot/entry.php?id=79 "the basic "warp sharp" algorithm"] by Avery Lee.

== [[Script variables|Syntax and Parameters]] ==
:{{Template:FuncDef|WarpSharp (clip, int "depth", int "blur", int "bump", float "cubic")}}
<br>
::{{Par2| |clip| |}}
:::Input clip.
<br>
::{{Par2|depth|int|128|}}
:::Warping strength.
<br>
::{{Par2|blur|int|3}}
:::Blurring passes on the edge mask. Higher values increase processing time. You must blur at least once, <code>{{Template:FuncDef3|blur}}=0</code> causes artifacts.
<br>
::{{Par2|bump|int|128}}
:::Edge mask saturation limit; no pixel in the edge mask will have a value greater than {{Template:FuncDef3|bump}}. Reduce for less aggressive sharpening. 
<br>
::{{Par2|cubic|float|0.6}}
:::Cubic interpolation coefficient. You don't need to touch this. 
<br>

== Examples ==
WarpSharp with default settings:
 [[AviSource]]("Blah.avi")
 WarpSharp (depth=128, blur=3, bump=128, cubic=0.6)
