I wanted to ask what people normally do when they are manipulating disparate images on the GPU ala videoplanes, and they want to preview the affected videoplanes before they go out to a rendering context.

I wouldn't normally want that, but I know that many people ask for it.

I cobbled together a solution using 4 duplicated rendering contexts (each with different names, which rendered dupes of each of the associated chains for the slabs and videoplanes), this can't be the way people do this- it's too inefficient.

1. 4 video planes that have jit.qt.movie/slabs going into them.

2. each video has multiple effects via stacks of jit.gl.slab

3. there should be a preview window for each resulting videoplane, ala jit.pwindow, so that the resulting affected video can be previewed before it is brought into the mix.

Just curious what people's approaches/experiences are to this problem.

Does anyone else have alternative methodologies?

Very excited that it's possible at all; wondering what people did before jit.gl.node.

Tobias - tried this patch - all I seem to get are white and black boxes..any thoughts?

nevermind! don't try to run slabs while watching netflix :)
