I've downloaded subtitles from Vesper and Magni streams and also added some video info (e.g. title, date, description) to the text files. These should be useful to people who want to search for sources of some specific quote (thought it's youtube's auto-transcription, so results may vary).
(The reason why the same text appears multiple times in a row is because I stripped out subtitle file syntax used to make individual words appear at different times.)
