1. Get the subtitles from Netflix (.xml dfxp or .vtt files), YouTube or other sources.
2. Convert them into .srt

• Note: There is a video-tutorial covering all instructions step-by-step in Youtube on how to to download and convert subtitles from Netflix using Windows and Google Chrome.

You need Google Chrome. not tested on other web browsers

1. Open devtools. This is usually accomplished by either:
   • Pressing Cmd + Alt + i.
   • Pressing F12.
2. Go to Network tab within dev tools.
3. Load your movie/episode.
4. Select the subtitle you want.
5. In devtools sort by name and look for a file with ?o= at the beginning of the name (see image below).

You need FireFox and AdblockPlus Add-On. not tested on other browsers

• Start Netflix and your movie/episode (stream is active!)
• Start AdblockPlus, open blockable items
• Search: dfxp (e.g. >> #.nflximg.com/#/#/########.dfxp?v=1&e=#########&t=######_#####&random=1234567890)
• open the dfxp in a new window
• Save as

• Install youtube-dl (available for Windows, Mac and Linux)
• Download subs from the YouTube URL you like e.g. youtube-dl --all-subs "https://www.youtube.com/watch?v=VHNfvFOBC0A"
• Subtitles should be downloaded in the same folder were the command was ran. E.g. NameOfTheVideo VHNfvFOBC0A.ca.vtt, NameOfTheVideo VHNfvFOBC0A.tlh.vtt
• If you are missing a language, check that it's actually available. E.g. youtube-dl --list-subs "https://www.youtube.com/watch?v=VHNfvFOBC0A"

• Get python (tested under python 2.7, 3.3 and newer). If you have mac or linux you may skip this step
• Clone this repository or download to_srt.py
• Run the script in the terminal (type python to_srt.py from the terminal on the folder you have to_srt.py)
  • Copy your subtitle files in the same directory as to_srt.py
    • Or use -i INPUT_PATH and -o OUTPUT_PATH for custom file locations
  • All .xml and .vtt files in the input directory will generate a converted .srt file on the output one
• Enjoy! (And star the repo if you liked it ;D)

VLC player could not reproduce that kind of xml subtitles and I could not find any tool that could easily transform the xml files to a suitable format (e.g. SubRip (.srt)) in Linux or Mac. I got a request for WebVTT (.vtt) and did the same.

• More robust file parsing than just some quick and dirty regexes
• Javascript/web version so this can be done entirely through a browser
• Real tests. The way to "test" it now is by running python to_srt.py -i samples -o samples from the the project's root directory and check the .srt results (or python3 to_srt.py -i samples -o samples).
• Create a pip package for this
