logical evolution of the long-exposure video-to-image processing i was doing a while back, now doing video-to-video processing with a decay factor

here's about 10 minutes of haneda airport (tokyo) sped up and processed to produce these delightful light trails

fucking mastodon, yes it's a video without an audio track, let people have video player controls instead of treating it like a gif of yore

oh, and the source video was from https://youtu.be/A0FCKcTuRHo

@luna gah i hate that. a while ago i tried to come up with an ffmpeg incantation to add an empty audio track. but then that sets the reported framerate of the video to 1000, which mastodon is not happy about. now i just leave whatever background music i was listening to in.

cool to see a program finally admit that the gif file format fucking sucks and is almost always just a video in disguise these days though

@luna irrelevant workaround: opening the video in its own tab, say by accessing https://cdn.pony.social/media_attachments/files/115/888/163/003/442/680/original/842257577cfd3fa5.mp4 , means the browser will probably show some player controls.

@luna Wow that’s trippy. I’ve never seen any effect like that before.

Very cool.

@luna I would love to see this treatment on dancers.

This old experimental film, “Pas de Deux”, uses a similar effect. Though it was specially lit and choreographed to work with the trails effect https://youtu.be/WopqmACy5XI

@luna isnt this the exact camera that caught the runway collision last year? Or am i completely misremembering that clip?
Show threadluna, friend of eggbugJan 14
@LordHivemindofCeres if you're referring to https://youtu.be/o2rswxU99Dc, it's the same airport but a different camera; i've used that angle for some of my video processing experiments too

@luna This is a great post process effect. Does it also work on daylit video?
Show threadIan K TindaleJan 23
@luna a long time ago I tried my then-relatively-new Sony NEX-3N (which I still have, or at least have back after a long time away) handheld video in Covent Garden at the end of a day, and it was too dim a light to give normal exposure so it seems to have given me video comprised of time exposures. It was really to test video sync to the mid-side mic I was using, but I became very much intrigued by this visual effect, especially all in camera (and hand-held at that!).

@luna Great effect, looks magical! Have been playing with this kind of Koyaanisqatsi inspired effects using optical flow and combined with a (I assume) similar post processing long exposure (some of it using difference matting) years ago: https://vimeo.com/36940726

An optical flow of processed video shows crowds of ghost like people floating though their urban environment washed over by natural forces. Running Time: 4 min.…
