Old network
As of Houdini 20.5, use Copernicus nodes instead of Compositing nodes. Though both networks still exist, the Compositing network is now designated as COP Network - Old. The Compositing network and its nodes will be deprecated and then removed in a future Houdini release.
De-interlaces a frame of video by either averaging scanlines or copying a scanline. You can choose which scanlines get kept, odd or even.
You can also choose to drop the scanline, which will then be replaced with a color of your choice.
Tip
Averaging almost always looks best.
Overloading VEX Parameters ¶
This operator is implemented in VEX, which supports parameter overloading. If the first input has a plane which matches an operation parameter’s channel name, the input plane will be used as the parameter’s value, effectively overriding it. The overloaded parameter is then evaluated from the plane on a per-pixel basis.
eg. If the input COP has the following planes:
C{r,g,b}
A
fogdensand it is fed into a VEX Fog COP, the fog density will be determined at each pixel by the fogdens plane, since the Fog Density parameter’s channel name matches the 'fogdens' channel name.
Parameters ¶
Field to Keep
Select Odd or Even fields to keep.
Method
What will happen when the field is dropped.
Average
The lines above and below the discarded field will be averaged together.
Copy
The line above the discarded field will be copied.
Drop
The space left by the discarded field will be filled by the color specified.
Drop Color
The color used to fill the gap if “Drop” is selected as the Replacement Method.
