I would like to know if there is a way to filter only a rectangular region of the frame!
For example, to put HIGHLIGHT on that region, or to BLUR it, or to ZOOM it, or to make it into B/W, whatever. (Maybe this could be a function of the VirtualDub itself.) |

It is possible to do this with a wrapper plugin, if you want to implement one.
A wrapper plugin is a plugin that does some generic work (cropping in this case) and can load and execute another (arbitrary) VD plugin to do some sophisticated work like blurring etc.
I am in process of development of similar thing but with somewhat different goal in mind |

Until shekh filter is made you could have a look here http://www.infognition.com/VirtualDubFilters/ where there is a few Virtualdub filters listed
For others look at the forum where you posted this post for the Important Topics located at the top. Where can find many plugins, filters. Or search here on the forum for what you need blur or an internet search engine for Virtualdub blur plugin as an example to find other filters and plugins not yet mentioned or listed on this forum |

Yeah, there are a great number of filters for VirtualDub (even I use regularly more than a dozen), but almost all of them make operations ON THE WHOLE FRAME (except the logo, the logo removal, and the subtitle type filters, and maybe a couple of others).
But I need to make certain (but many kind of!) operations only on a SELECTED PART of the frame. I suppose the simplest case is a rectangular region (that could be selected the same way as cropping), but it would be better, if we could select a circular, elliptical, or even an ARBITRARY region too, defined by a MASK, for example.
I don't think that this functionality should be built into the (huge number of) filters, it seems the better way is to build into the VirtualDub itself. |

The solution is Filter Blender by Steven Don.
You can setup a mask to have a string of filters apply to just one region of the video. You setup the mask, and then switch to path B. After you put in the filters you want masked, apply the FB again and switch to path A.
I have petitioned for a VD enhancement so that filters could all be applied using a mask, but this filter is a way of doing that same thing, but to my taste more kludgey.
It is available at:
