ttml/.vtt/.srv to srt converter I found solutions that required installing Python or some other large scripting language. Change the format to whatever is preferred. I usually try itag=18, mp4/360p, if 22 is not available. The video format is itag=22, i.e., mp4/720p. mp4, where is a 10 or 11 ASCII character string. Obviously, it will not work with commercial videos. This is slow YouTube downloading without using yt-dl/yt-dlp. srt and then "hardsub" them into the video as it dowloads the. The script above, "1.sh", can be used as follows. In case anyone's interested or wants to help (for Sanskrit texts): see deployed at and better version at deployed at į=$ in 10|11)Įxec ffmpeg -v quiet -y -i $video -vf subtitles=$f.srt $f.mp4
Something like this can also help with audio recordings (generating the alignment automatically is called "forced alignment" and there are tools like "aeneas" for this). keeping the video and text in sync (just view source on either page to see the JS at the bottom). It takes just a few lines of Javascript, using the Youtube API, to do this i.e.

I had done something like this a couple of years ago for some specific set of videos (e.g. This is a great idea I really enjoy all these "two channels simultaneously" (side-by-side translations, video with subtitles, and in this case video with a readable transcript, where you can scroll in the video or scroll in the transcript, and be synchronized).
