This look interesting. I'll need to test it out. I'm a, little it puzzled what does subtitle support means. I guess it is possible to embed them directly into video.
Thanks for your feedback. It automatically generates sub-titles in VTT format.
Or you can our own video player to display sub-titles in multiple languages for a video.
Embedding subtitles directly into the video stream is a bit more complicated. Interestingly a lot of video creation platforms don't support that as a feature even though it's useful in some cases (E.G. videos on instagram/tiktok/etc.) I actually had to write my own service on top of ffmpeg to do this shrug
