How would I achieve the digital distortion effect seen in this David Bowie video from 6:20 to 7:10? Is there a term for this effect to help guide future searches?
Can't embed the video, so here's a screenshot
Tough question, and I imagine that those effects may be combinations of many other effects (probably in a 3D package given the context of the video itself). Barnaby Roper has a pretty interesting skill set, and we could try forever guessing what he did without getting it exactly right.
That said, you should be able to accomplish a similar effect with purposefully induced compression artifacts. Getting those artifacts to animate seemingly organically like the video will be tricky.
Otherwise, dig into After Effects and start playing with combinations of all the distortion. Trapcode's Particular is (unsurprisingly) used throughout, but it's hard to pin down exactly what they're using it for everywhere. Still, Trapcode does have a small blog about the video, which might be able to direct you to further expertise:
You may also want to look into Trapcode MIR: http://vimeo.com/46449353; I don't think it was used for the distortion you've highlighted, but it's possible.
