I get what you're doing, OP. I don't have the tools (time being the prime) to do it though.

Ok, this is pretty cool, but how do we encode it?

There was also another version done by /tech/ that could withstand youtube's compression algorithm.
I'd ask them in the sticky maybe.

It's easy, but this method won't survive lossless compression

create a zip of the file, add null bytes to it with "truncate -s +5000 file.zip" so the last frame can be completed.

For mp4, 66x66 can be whatever resolution you want

ffmpeg -f rawvideo -s 66x66 -i file.zip -crf 0 output.mp4

for vp9/webm

ffmpeg -f rawvideo -s 66x66 -i file.zip -c:v libvpx-vp9 -lossless 1 output.webm

this can survive lossy compression


#!/bin/bash
#warning: this pads 0s at the end of the input file so the last frame can be completed. zip the files first and only use the zip as input.

input=$1
width=1280
height=720
rate=30

##pad input to avoid truncation
framesize=$(($width*$height/(8*8)/8))
truncate -s %$framesize $1

ffmpeg -f rawvideo -pix_fmt monob -s $(($width/8))x$(($height/8)) -r $rate -i $input -vf "scale=iw*8:-1" -sws_flags neighbor -threads 8 -deadline best -c:v libvpx -b:v 256k output.webm

Decoding command

ffmpeg -i <input-file> -vf "format=pix_fmts=monob,scale=iw/8:-1" -sws_flags area -f rawvideo <output>

Damn I wish I knew how to use a computer.
Guess I'll just stick with making plain images into extractable zips and sharing whatever the fuck this first image is.

4chan detects images with embedded zip files, I think Holla Forums used to remove them too.

present.jpg has one hidden in it. If it extracts then you know it doesn't strip the embedded files.

It's probably cloudflare, when they cache images, they sometimes strip junk data after EOF.
