Allows you to download subs from Netflix shows and movies.
Subs downloaded in WebVTT format. No, I won't create half-assed converter to SubRip, you can use Subtitle Edit for this. To convert a whole folder create .bat file with following content:
cd /d %~dp0
SubtitleEdit /convert %1\* SubRip /multiplereplace
place said .bat file next to SubtitleEdit.exe and drop folder with subs onto .bat file. If you need to replace some strings open Subtitle Edit, go to Tools, Batch convert, open settings of Multiple replace and add some rules.
