I find myself downloading a lot of movies that are dubbed in latino Spanish. I've checked fmhy torrents, but unfortunately, there just isn't a lot of latino Spanish content available on torrents.

(Yes, there is a lot of Spanish Spanish content... but... meehhh...)

However, I have had better luck with fmhy streaming. It's not the best quality, 720p or 1080p if I'm lucky. But it's better than nothing.

I was recently wondering, how does dubbing actually work? Is there a video difference between English and Spanish movies? Or is there just literally an audio track being swapped out?

Could I take an audio track from a 720p stream and add it to a 4K torrented movie file and expect the audio and video to line up?
