If yes, then here’s a gig where you can order burnt-in English subtitles and translations to be added to your video.

I’ll even customize the font style (if I have your preferred font style), background type, font size, and the text color for your subtitles. The subtitles will be in sync with your video’s audio, too! 
If you’re interested in this gig, you may ask me for more information. Thanks!
