There are a couple of well-known speech recognition apps available online that can easily convert any audio into text format, however, most of them are paid. Being a global language it is very easy for most of the world’s audiences to understand your created video content easily. As we know YouTube is not only limited to one country or vicinity, so if your videos’ language is English then it is really easy to automatically transcribe Youtube videos. However, here we are only going to talk about one which is Youtube auto-transcribe service. I wrote a shell function instead.Youtube is the most popular video uploading & streaming platform with lots of features such as background color change, keyboard shortcuts, translation of video titles and descriptions, auto caption generation, and more. On GitHub I found a project called "astisub" that will convert from ttml or vtt to srt. 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.
compare with for the same video), but never got around to making it general glad someone has done it. 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).
