Why is AV1 a bad choice for that "something" ?? No, why would I want Electron ?? IMHO EPUB should specifically be script-free. And if I wanted scripts in my document¤, then instead of packaging the whole browser (that would be overkill!!) with the document like Electron does (?), I would rather use MHTML. ¤ The following was supposed to be my example, but since this website uses Flash, these scripts are no longer easily ran. But since they are described, you should have a good idea what they are going for : http://resonanceswavesandfields.blogspot.com/2007/08/phasors.html http://resonanceswavesandfields.blogspot.com/2007/08/phasors...

  > MHO EPUB should specifically be script-free. Agreed. Yeah maybe I am just knee jerking, with AV1. Broadly speaking however there would be two schools of image and video compression, one for computer generated images and one for images of natural concepts. So AV1 isn't really suited for animated graphs and the like at the end of the day. On second thought maybe allowing in AV1 would open the door for sound, which really would take us to far away from the book format. I do definitely see the need for having animations such as the ones you link in your post however. So many things that just takes sentence and sentence to describe can still be described way more efficiently with an animation. CSS Animations or animated SVG maybe?

    Hmm, I should really look into vector graphics one of these days. Yeah, animated SVGs would be even better for this use case - but you need raster graphics support too for other use cases (some animations might require the inclusion of photographs). I don't see how sound support is an issue - no more than color and high frame rate support are issues for a format that might also end up displayed on grayscale only displays incapable of high framerates. It's up to the creator of the media to take these into account (or not).

      Ah yeah me to only realised that you could animate them while writing the comment above. I think that we should define a book as something that you can use only with your eyes. If I bought a book and I would need to use headphones to "read" all the content in it I would feel a bit defrauded.

        But epubs aren't books. What is the point of trying to artificially restrict a format ? (Though a (sub?)format dedicated to "e-ink" readers might actually be a good idea ?)

        Yes epubs aren't books. I think you really nailed it there. E-ink display devices would have a way lower refresh rates from what we are used to and are as such probably really bad at or unable to play video.
