My main problem with non-entertainment, prerecorded video is how little control you have on how you consume it, when compared to text. Consuming video is too linear and opaque.<p>When you open a book, article or even forum thread you have immediate access to all the content, can quickly skim through the index, chapters, headings, posts and make a mind map of what's happening. You can adjust your reading speed on a sentence basis. Jump back and fro, Reread a difficult passage 10 times effortlessly.<p>Video on the Web is basically no better in that area than VHS was. You get a clickable timeline, timestamps and that's that?<p>Transcripts are a starting point, but a bit useless without a proper TOC. Now, if you get that part right but the video is just someone talking, the video itself becomes redundant (for me anyway, I know people are different.)<p>Visuals-wise, some platforms have a quasi-instant lowres preview when you move the timeline cursor. A nice upgrade on that would be to show the transcript and possibly section (drawing from the TOC idea above).<p>I can't think on how to greatly improve this, but you did ask what we disliked.
