I've been in amateur video translation/subtitle scene since 2013 and made over 700 subtitles(avg. 10 min per video). I'll send the OneDrive link if requested.

Even though most them are Korean only, You'll see how accurate my time coding is.
The reason why I don't have English subtitles is those are translated from audio.

Any decent translator can translate subtitles. But I'm sure those translators can't time code a video or knows which is best for viewers.
