YouTube Flashcards

Extract screenshots & audio clips from YouTube videos into Anki cards.

📖 使い方（日本語で）

Installation

You'll need to install youtube-dl and ffmpeg:

brew install youtube-dl ffmpeg

Usage

Download

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.

Extract

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

Import

Finally, import the cards into Anki:

• Copy the audio and image files from ./output to 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.

Offline videos

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.
