Does anyone know of a tool (extension?) that will translate captions (even badly) for YouTube videos? Sure I could you use youtube-dl and run the result through Google Translate, but I'm looking for something automated.

This is natively supported on youtube, at least some of the time. I think it might be that you have to have youtube's UI language set to a different language than is spoken in the video.

  As far as I can tell, it's available on desktop, but neither in mobile browsers nor the app. The video language being the same or different from the UI language didn't seem to make a difference. My current working theory is that they couldn't figure out a way to fit a two-level menu on a phone screen, so they just cut that feature...

    I just tested, and yes on desktop there is an 'Auto-translate' option, even for videos with 'auto-generated captions'. However on mobile (YouTube app on Android, Firefox, Chrome) and my TV the 'Auto-translate' option is missing, so I can only view the generated subtitles in the original language. I mostly watch on mobile or TV, so :-/

Someone else posted youtube-dl args to get the transcript in its original language. It's pretty easy to rig a translation script using pretrained models. [1] If you are building a historical dataset, it's probably better to cache the transcript in its original language, so you can benefit from improvements to translation models as they develop.

This is the equivalent of "use youtube-dl and run the result through Google Translate[1]:" youtube-dl --sub-langs [DESIRED LANGUAGE] [1]: https://github.com/ytdl-org/youtube-dl/blob/master/README.md#subtitle-options https://github.com/ytdl-org/youtube-dl/blob/master/README.md...

JSON.parse(ytplayer.config.args.player_response).captions.playerCaptionsTracklistRenderer.captionTracks[0].baseUrl just add &tlang=XX where XX is one of JSON.parse(ytplayer.config.args.player_response).captions.playerCaptionsTracklistRenderer.translationLanguages
