Transcripts might contain timestamps but often have the option of toggling them on or off in the video platform.Subtitles can be styled to include bolded or italic text or different font and background colors, depending on the file type of the subtitles.Transcripts are stored and displayed as plain text information.Subtitles are integrated into the video either as closed or open subtitles.Transcripts are separate from the video, often appearing on the side or below a video player.Subtitles can be in the same language of the video or translated into multiple languages.Transcripts only capture the language in the video.Photo by Glenn Carstens-Peters on Unsplash Differences between transcripts and subtitles And both are text files that can be updated in a text editor. Both can be used to follow along with the video without relying on hearing the speech itself. Transcription is writing down text that captures all of the speech in a video. Creating transcripts and subtitles starts with transcription. I wrote a shell function instead.What are transcripts and how are they different from subtitles and how can they be used? Let’s start with what they have in common, discuss the differences, and see how easy it is to convert YouTube captions to text files. 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).
