I'm trying to fuck up a video for unclear reasons.
The video was easy, I just maxed the compression and resized it down to 18x12 (though I'm thinking of scaling it back up, then hardsubbing some captions from another movie)
the audio was the tricky part. I've downmixed the 5-channel surround into mono, lowered the sampling rate to 2000hz, and now I'm over-dynamics-processing it so that all the loud noises (it's an action movie) get smudged into nothingness.

@foone@digipres.club I have a tiny function in my .zshrc for fucking up videos. It uses an external dependency tho, but aside from that, it uses ffmpeg.
Without the external dependency, it's just normal compression stuff.
With the dependency, it adds some datamoshing (i-frame deletion).
If you want, I can reply to this toot with the function.
Basically for the ffmpeg part it puts the audio bitrate to 20kbps, resizes the video to a small resolution and to 10fps, then resizes back to a viewable resolution.

@foone ooh we’re in my wheelhouse, this sounds fun
Have you even tried some ancient codecs from the MPEG-2 era, like Sorenson codec? Probably better just to go for H.261 instead.
I think you went the wrong way by removing stereo — that makes it easier to maintain quality. (Same could be said for pixels instead of bitrate, I guess). Just go for all those joint-stereo hacks.
Heh you’re not trying to reverse-engineer YouTube’s content ID by any chance? 🫠

@whophd nah, my roommate just wants me to give her a very shitty version of Armageddon (1998)

@foone of course the 1-click solution would be to dive into China’s basement of VideoCD (VCD) collections from the 1990s and just buy the movie … though that’s still vaguely equivalent to “bad VHS”

@whophd yeah! videocd was the first target I aimed for, actually.
I then did "featurephone" and now I'm doing "just bad"

@foone ooooh petty? Like extremely geekily petty?
I think the true benchmark is dialup video, as invented by RealPlayer / RealMedia. It might take one or two layers of emulation and/or pre-conversion to get it encoded, but I think an “.rm” file can still be opened by VLC VideoLAN
28.8k dialup meant a 24kbps total stream, with about 16 for video and 8 for audio. The video would have been about 80x60 — and loads of macroblocking within that, not a GIF level quality — with a variable frame rate depending on “motion energy”, but a nominal (maximum) rate of 8fps. But often dropping to 1fps or 0.5fps when action got Their RealPlayer client did some fun motion blurring, “tweening” frames to make this limit less painful.
