How is this done?

His description of the video states a custom plugin, I've tried with stock patches, queues, iterators, cropping etc but I can't even get the same effect running slowly, just crashes. Can anybody even get close to this? It's such a fantastic effect.

Search for "slit scan" here, and check out some of psonice, etc. work. I think they may have been working with CI and the guys you reference above are using GLSL. Perhaps this is why they are getting 60fps. I don't quite follow the "3D Texture Mapping" comment, but maybe that is another hint as how they get good framerates: with the 3rd dimension mapped to time. Basically, you just want to break your video into "scan lines" and then f*ck with the temporal composition of the output frame. How were you approaching this in your efforts? Might also look at the "bad tv" effect, for ideas.

You don't really need any special things to build something like this, I guess. Here is a very basic patch which do something like the video, but it actually slow because of the image cropping.

I had exactly what .lov has provided, minus the extra bits to change the slice size/copy amount. I tried it with bangnoise's sampler too. It's unusably slow, would be great to know if a GLSL version of it is around.

I find they both run at similar rates on my new machine (unless I pump up the iterations into the hundreds). I also get a slight flicker with .lovs method whereas Toms plugin is smooth. Have you tried contacting Adrien M ?
