I am working with a stationary camera angle of a row of people where
the closest person is on one side of the video frame and and the furthest
person is on the opposite side of the frame (and the furthest person is
smaller... naturally).
I am looking for a filter for virtualDub (or aviSynth) which will allow me to
stretch/warp the input video such that the output video displays
the smaller/furthest person at the same height as the closest person.
I don't care about the artificialness of the result (the strange perspective).
I've searched and couldn't find anything very close.
Ideally I'm looking for this:
A filter allowing the user to specify four points in a sample source frame.
The filter then stretches/warps the input frames such that the specified
four points end up at the four corners of the output frames.
Does anyone know of a filter which does this?

1000 thanks.
Here are some links I found for reader'ss convenience:
(I wish these pages also used words such as warp or stretch... anyways).
googleSearch:
- http://www.google.com/search?hl=en&ie=UTF-...tualDub&spell=1
I found only one download address:
- http://avielle.chez.tiscali.fr/video/quadr...drilateral.html
The filename is:
- quadirlateral098.zip
Note:
The only thing I found noteworthy is that one needs to deselect
'Show Input Selection' before rendering. I don't think this is
a bug, just potentially misleading (in that the input selection isn't
only shown in the preview, it will get rendered). Other filters do
this kind of thing as well, yet I thought it was worh mentioning
to newbies such as myself. Don't be alarmed, the filter works.
Thanks again.
