emulating toshio iwai
This is an attempt at emulating a simple but beautiful piece that toshio iwai showed at the last ars electronica. Basically a video is divided into different portions and each of them is delayed by a certain amount of frames.
Thanks to the magic of openframeworks, it is realtime video.
More explanations, some code and a video coming soon.

This was used to incredible effect in the video clip for Muse - Unintended

Fantastic to see it in realtime though!

wow, seems like they have a couple more pixels of resolution than I do… seems really nice.
Anyway, I’ll try to push resolution as much as I can, as I’m interested in seeing how far I can get with c++

The technique is called Slitscan, and has been used extensively in photography and video for some time (many of the movie ‘2001 Space Oddesy’ use the effects. Depending on what axis you scan by (vertical or horizontal), you can get some very nice effects, especially with rotating objects, like doors, people spinning, etc. Wesley Smith has a set of objects for Jitter to allow arbitrary lookup tables for a buffer of frames, allowing one to re-create slitscan vertically, horizontally or.. arbitrarily.
That video did have quite high resolution. Im curious how they did that, or if they ran the video slowly, and then sped it up (the amount of difference in a frame, if very high, will produce large jumps from line to line, so there is a direct limit of how fast your motion, and how fast you scan vertically or horizontally before you have visible artifacting.
Anyway..

I didn’t know its name. Nothing like a word to do some googling.
