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.

That's what's so sad about youtube. 20 minute videos to encode a hundred words of usable content to get you to click on a link. The inefficiency is just staggering.

		Youtube can be excellent for explanations. A picture's worth a thousand words, and you can fit a lot of decent pictures in a 20 minute video. The signal-to-noise can be high, of course.

Average high quality 1080p60 video has bitrate of 5Mbps, which is equivalent to 120k English words per second. With average English speech being 150wpm, we end up with text being 50 thousand times more space efficient.

Converting 22GB of uncompressed text into video essay lands us at ~1PB or 1000TB.

Right? 20 years, probably 10s millions of human hours of interactions, and it’s only as much as a couple DVDs.

one could use a video llm to generate the video, diagrams or the stills automatically based on the text. except when it's boardgames playthroughs or programming i just transcribe to text, summarise and read youtube video's.

How do you read youtube videos? Very curious as I have been wanting to watch PDF's scroll by slowly on a large TV. I am interested in the workflow of getting a pdf/document into a scrolling video format. These days NotebookLM may be an option but I am curious if there is something custom. If I can get it into video form (mp4) then I can even deliver it via plex.

		I use yt-dlp to download the transcript, and if it's not available i can get the audio file and run it through parakeet locally. Then I have the plain text, which could be read out loud (kind of defeating the purpose), but perhaps at triple speed with a computer voice that's still understandble at that speed. I could also summarize it with an llm. With pandoc or typst I can convert to single column or mult column pdf to print or watch on tv or my smart glasses. If I strip the vowels and make the font smaller I can fit more! 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.

Can be nice to pull a raw transcript and have it formatted as HTML (formatting/punctuation fixes applied).

Best locally of course to avoid “I burned a lake for this?” guilt.
