Smarter Speed-up

[ImprovedTube]

Speed-watching by whitelist:

• Speed by category: instead of forcing speed always you could only apply that to specific categories and in characteristic proportions. The biggest categories tend to be contentually slow & well spoken/pronounced too
  
  • Entertainment & Gaming ( 37?% of Youtube!)
• Speed by transcript (easy transcripts, speed by current paragraph's language difficulty/average word length ...)
  • (Skip silence? Skip silence #921)
• Speed by meta-info: words like "Keynote" (commercial, rather sort) can play faster than "lecture" (academic, rather long)
  • more precisely, peak interest & word-/syllable-speed can be considered! Youtube's Timeline Heatmap (Histogram) enables/improves a lot... #1463 Skip silence #921 (dynamically/porportionally. Not only per Video (but also per Chapter, Sentence or proportion to the per whole video & channel & category)

Permanent speed-watching exclusions /blacklist.

• Short duration
• Difficult Transcript (~long words)
• Category: education (~4%?)
• Art
  • Silent or no words (=No sound and/or empty transcript, or hardly any.)
  • Poetry read out; ...?; ...?
  • Music (blacklisted by default, yet non-greedy (=attempting 0% false positives), so that a "1% error-rate" will rather mean accidentally changing speed of "1% of music" ("false-negatives"), than matching any non-music.
    • The category is music ( ~19?% of YouTube, mostly honest/accourate? /the rare case of category-spam might not matter)
      • or a "music-identifer" is included like (official video lyrics (cover version) karaoke sing-along soundtrack)
      • but the video title & tags/keywords contain no word like interview, documentary or backsage
        • (While this covers a majority, not all languages are added yet & the word 'documentary' could again be required to not have a certain length unlike a song. etc. etc. Or every song-title with such word could be whitelisted (funny/rare)
        • Also considering duration and the word "Album"
        • Music may also be: When YouTube recoginized a song(/songs), thats registered /can be bought and duration fits.
        • Beat-detection in the sound data iself?

"Speed-watching" (many users dont literally watch, so:)

• "Speed-listening": Option: Only speed-up while tab is not visible
• "Speed-reading": More Subtitle- & Transcript-options [with an invisible [and/or mute] player]

• In the end of course a permanent personal default speed might stay "only" semi-automated and you might decide differently for a few % of videos - so it should come with a "quick-reset-button" (we already got a keyboard shortcut for resetting speed)
  • GUI & idea

( fixed speed by category #680 )

Maybe you like to see the above? (Many of you have cared before*)
(I'm not a "speed-watcher" myself yet, but based on the assumtion, that there are at least 1 million people in the world, who should be active "speed-watchers",...)
...- why isnt there a more coordinated teamwork /"lobby"? /Why isn't there a bounty on this issue thread - so that some poor developer/s would already have done all of it & more.
