a composite of a cropped video rect on another video


i have what i assume is a simple question.

how might i cut out a rectangular portion of a video and superimpose it onto another video.

a window onto another film.

and if that works, is it possible to make a background video with on top several windows?

i’ve explored usesrcdim, usedstdim, alphablend but can’t seem to figure it out.

thanks in advance.

Hi Jeff,

i’d use jit.submatrix to reference part of my big video image
i’d superimpose using jit.xfade or combinations of jit.ops
i’d paste the result back in using usedstdim 1 and the appropriate
dstdimstart/dstdimend coordinates..

you could repeat this a few times to get more complex results..

good luck and see you again sometime soon, i hope…
