I have never thought of gathering a script of a video, also never thought there could be a tool that does that and also translates it. I believe having a script could be beneficial for certain students. Also a benefit would be to easily search keywords through it.
This tool downsub seems to be doing that just by a click. Just copy and paste the link of the video you want to get its script.
I tried on a video and it didn’t work and so it seems it is not applicable on all videos.
But then I tried another video and I was amazed at the speed it generated the file.
Translation option (though I couldn’t see it in my second attempt)
Auto-generated risks accuracy
Too many adds all around the website!
Some video don’t work
