version: 1.4
category: Broadcast Video Plugins
requirements: YV12 & YUY2 Colorspace


Note:The left and right parameters get doubled by the filter as I haven't sorted out how to deal properly with having 1 chroma sample for very 2 luminace ones yet :-(

It performs the same functions as the VirtualDub version in that you can set a black border, set a border region to be faded out and you can "smear" the border to save having to crop and resize the whole frame for the sake of a few pixels. Each border (top,bottom.left and right) can be manipulated independantly.


BorderControl(YBB=16, YTS=32)

This would put a solid black border at the bottom and smear some lines at the top of the picture. The plugins accepts up to 16 parameters, 4 for each border
There are 4 prefixes: YB, YT, XL and XR for bottom, top, left and right borders.

There are 4 suffixes: B for Border - this sets the amount of solid border, F for Fade, S for Smear and SF for SmearFactor.

Increasing SmearFactor (having first set the Smear value correctly) can help disguise the smear region at the expense of increasing the area being processed. I suggest using even values for YTSF and YBSF when dealing with interlaced material.

So the parameters are
BorderControl (clip, "YBB", "YBF", "YBS", "YBSF", "YTB", "YTF", "YTS", "YTSF", "XLB", "XLF", "XLS", "XLSF", "XRB", "XRF", "XRS", "XRSF")
