scripts to search in a collection of youtube subtitles. In what video did your favourite youtube person use a certain word? Now you can find out without going through their videos manually.

the search scripts expect a collection of srt clean subtitles. you can use autocollect_subs.py for this. python autocollect_subs.py {URL} the URL can be anything that youtube-dl can get subtitles from. e.g. youtube channel,youtube-playlist, or just a single video. the default option right now is to download all subtitles, consider changing them to you need eg '--write-auto-sub', '--sub-lang', 'en',

Windows10 64bit, making it work for other platfrom should only require minimum efford though, Python 3.x installed.

All of these files in the same folder as the autocollect_subs.py script:

• ffmpeg.exe
• youtube-dl.exe
• subtitle-overlap-fixer.exe

downsub.com gives you clean srt subtitles from youtube videos right away.

youtube-dl can take care of that for us. ./youtube-dl --write-auto-sub --sub-lang de --sub-format vtt --skip-download [channel or playlist URL] -o "%(upload_date)s-%(id)s.%(ext)s" this gives us a collection of vtt files

youtube-dl can convert subs using ffmpeg, but only when the video is downloaded. use ffmpeg directly to convert .vtt subtitles to .srt.

./ffmpeg -i '{vtt-FILE}.vtt' '{SRT-FILE}.srt'

you can use the 'convert_to_srt_local' scripts to convert serveral subtitles in an automated way. place the script in a folder with .vtt subs and ffmpeg.exe, then execute the script.

When you download youtube subtitles with youtube-dl and convert them to .srt using ffmpeg, the subtitles have overlap and double lines. This go script from nimatrueway fixes that.

usage ./subtitle-overlap-fixer '{SRT-FILE}.srt'

uses find to search in srt lines. expects a folder srt_fixed as a subfolder (as produced byautocollect_subs.py )

'python listsearch.py' term1,term2 or just run `'python listsearch.py' and enter the search terms manually

uses fuzzymatching for finding words have the module 'fuzzywuzzy' installed pip install fuzzywuzzy

use 'python listsearch.py' term1,term2

output a search results.csv link goes directly to video with time where the line with the term is said.

resline,id,duration,resurl

Line with term1,XXXXXXXXXXX,"00:06:49,199 --> 00:06:51,810",https://youtu.be/XXXXXXXXXXX?t=409
