A great extension. It's simple, easy to use and had everything I needed.

これはすばらしい。Background無しで見やすい字幕にすることができた。

Exactly what I was looking for, it has text outline option called "stroke". Very helpful because default subtitles blend with a video, even changing color doesn't help.

It's good enough. I hope it gets applied to shorts too.

非常棒，這就是我想要的字幕加強套件！
