Extract screenshots & audio clips from YouTube videos into Anki cards.
You'll need to install youtube-dl and ffmpeg:
brew install youtube-dl ffmpeg
First, download a video that you know has subtitles in your target language:
./download.sh 'https://www.youtube.com/watch?v=5P3Tb_v-KnY'
That will download the video and subs into the ./downloads folder.
Next, extract the cards (it may take a while):
./extract.sh downloads/Frau_Holle.mp4 downloads/Frau_Holle.de.vtt downloads/Frau_Holle.en.vtt > cards.tsv
The parameters are:
- The video file
- The subtitles file in your target language
- Optionally: the subtitles file in your native language
Finally, import the cards into Anki:
- Copy the audio and image files from
./outputto your Anki media collection folder. - Import the cards TSV into a deck. There are 4 fields in the TSV: original subtitle, translated subtitle, image and audio.
You can also create cards from local files other than from YouTube. The script requires that the subtitles are in the VTT format. To convert from SRT and other formats, use http://www.webvtt.org/ or https://github.com/nwoltman/srt-to-vtt-converter.
