This video shows the test of a software developed as a programming exercise.

The image is digitally manipulated by fragmenting it into horizontal lines and then combining lines from different frames in the display. The result is a distorsion of the figures caused by their motion in time, or, as Brazilian researcher Arlindo Machado calls it: chronotopic anamorphosis.

The effect was completely based on Zbigniew Rybczynski's "The Fourth Dimension", but transposed to Processing programming environment and performed in real-time.

The software still has some memory issues, specially when the image rendering is combined with video recording, as it can be seen in this video.

This experiment was made within the context of Marginalia Project. More information about it, as well as the source code of this software [soon], can be found at marginalia-project.blogspot.com.

    really like ur door example :)
    i need to find "the fourth dimension", got a feeling my local video store won't have it...

    agree
    i love your door example too!
    but what caused the jumpy lines?
  • Marginalia Project 4 months ago
    This was caused by the memory issue I referred to in the description. My computer wasn't able to render it all nicely when I also used it to record the video produced.

    But I figure it was caused by poor programming, actually, as well as little knowledge on Processing, so far. We're working on it.

    Thanks for your comment!

    The door example was brilliant! I briefly experimented with this a while back using After Effects and also had the same problem with the jumpy lines.

    Will be waiting for the source code. :)
  • Marginalia Project 4 months ago
    Great to hear that! For now, tou can find the source code in Processing discourse: processing.org/discourse/yabb_beta/YaBB.cgi?board=Exhibition;action=display;num=1213382538
    We're still making some changes in it. But the basis is all there.
    Thanks for your comment.

    It's interesting that you are doing it in real time (I've seen something similar in Java.)

    This effect has been an After Effects plug-in for at least 10 years (time displacement.) The tutorial even uses a similar setup (a door opening.) A nice use of it can be seen here: youtube.com/watch?v=I2MsDogV4g4

    hey, great example.
    I wasn't aware of this plug-in. Looks very nice! Like the walking example.
    Anyhow, just made ir for the fun. It's very nice to know of these other experiments.

    Very cool. I was inspired to do the same thing a while back vimeo.com/438009 (it uses Flash instead of Processing)
  • Marginalia Project 3 months ago
    Looks very nice!
    Liked the online experience possibility. Very cool.
    Nice to know of it!

    Whoah. It's like the camcorder was on acid.

    Trippy.

    The fact that it's real time is the best part. The recording is cool, but I'd love to see a projection of myself with this effect layered on like some fun house mirror.

    despite the fancy name, this is what is known as slit scanning.

    flong.com/texts/lists/slit_scan/

    to see it in an accessible digital format is wonderul, I can't wait to try it.
  • Marginalia Project 3 months ago
    Hey, when we first did it we didn't know of slit-scan so far, we just knew of it from Rybczynski's work. But, anyway, we've never actually thought of it as something new, but just as an experiment on a known process.
    Casey Pugh (some comments up) has a similar project on flash and it looks great - besides, it's a lot more accessible than ours.
    Thanks for the comment.

    Nice work : ) and noticed your views spike to 47,000 in one day recently, crazy! would've expected far more comments tho... did the video get posted on some big site to drag those people in?

    wonder how easily this coul dbe achieved within quartz composer?
  • Marginalia Project 3 months ago
    Yeah, some blogs published a link to this video - sometimes quite out of context, claiming it as a "new video technology", when it's actually quite old. Some people have done it in other environments. I'm not familiar with quartz composer, but it seems that some people have done it in it.
    Thanks for the comment.

    I saw a video on Youtube not long ago where this technique was used using a female model in a bikini walking across the screen and doing various demonstrations. Very neat effect.

    This is really amazing. How/when can I get the software? Is it available as a Final Cut Pro plug-in, by any chance? I'd love to use it for a music video that I'm working on, if possible.

    Please email me at feinsodville@gmail.com if you want to discuss further.
  • Marginalia Project 3 months ago
    Hi, the program code is available at the Processing discourse forum. There's a link in a previous comment. But it works for real-time video only. You could adapt the code to use it in recorded footage or (much more easy) use the Time Displacement plugin in After Effects to reach similar results.
  • Mark L. Feinsod 3 months ago
    Thanks for getting back to me. Using the Time Displacement plug-in in After Effects seems like the way to go. Thanks again!!

    looks awesome, you can also do this with the time displacement filter in After Effects

    Hello,
    I've done exactly the same prototype in ActionScript 2 (flash). Realy easy to do and applicable on a website with the flash plugin.
    Same final tuning to do with memory.
