    I love this so much! This is such a cool hack, just for the sake of it. Amazing hacking and amazing art!

    In the preso, she has said the full size output is on the website-

    can anyone see what that link is? I didn't find it on the video page, but I might've just missed it.

    It would have been pretty easy to use a horizontal line scanner to get image speed.

    In any case, it seems that using a full frame video would be much easier to post process since frame to frame correlation tells you everything you need to know about motion.

      One of the first scripts I vibecoded did exactly this. It works well, but is limited by framerate when there's high motion.

      I'm not sure that video would have been easier to postprocess. At what fps and shutter speed?

    Using the camera as a scanner has a long history in satellite cameras and other aerial photography
