This is an Enterprise only feature
When you have a clip open on the Uploads page or the Library you can download subtitles for this clip.
What if my clip isn't English?
If the clip is in a non-english language it will download both the original subtitles and translated subtitles.
You can distinguish the two downloaded files by the first two letters which represent the language code, for example: en for english and es for spanish.
What format will the file be?
These are in SRT
