What a reminder on how text is so much more efficient than video, its crazy! Could you imagine the same amount of knowledge (or dribble) but in video form? I wonder how large that would be.
For example, one of the most useful applications of video over text is appliance or automotive repair, but the ideal format would be an article interspersed with short video sections, not a video with a talking head and some ~static shaky cam taking up most of the time as the individual drones on about mostly unrelated topics or unimportant details yet you can’t skip past it in case there is something actually pertinent covered in that time.
I've produced a few videos, and I was shocked at how difficult it was to be clear. I have the same problem with writing, but at least it's restricted in a way video making isn't. There's so many ways to make a video about something, and most of them are wrong!
Converting 22GB of uncompressed text into video essay lands us at ~1PB or 1000TB.
One could convert the Markdown/PDF to a very long image first with pandoc+wkhtml, then use ffmpeg to crop and move the viewport slowly over the image, this scrolls at 20 pixels per second for 30s - with the mpv player one could change speed dynamically through keys.
ffmpeg -loop 1 -i long_image.png -vf "crop=iw:ih/10:0:t*20" -t 30 -pix_fmt yuv420p output.mp4
Alternatively one could use a Rapid Serial Visual Presentation / Speedreading / Spritz technique to output to mp4 or use dedicated rsvp program where one can change speed.
One could also output to a braille 'screen'.
Scrolling mp4 text on the the TV or Laptop to read is a good idea for my mother and her macula degeneration, or perhaps I should make use of an easier to see/read magnification browser plugin tool.
Best locally of course to avoid “I burned a lake for this?” guilt.
