The other day I happened to see live content with closed captions, and I thought I would love the option to see subtitles like this, where words are translated precisely when spoken.
You generally only see word for word matches with subtitles when the subtitles are in the same language as the original lines spoken by the actors.
Since I’m moderately familiar with the other language, I really just need the translation for words I don’t understand or mis-hear.
There is such a thing as a real-time translation. I’ve heard it in news broadcasts when a politician speaks a foreign language. It also happens all the time at the UN and other international negotiations. It works well but has downsides such as occasional latency while the translator needs to hear a few more words before they can translate.
Something that might be sort of like what you are looking for is Language Learning with Netflix https://chrome.google.com/webstore/detail/language-learning-...
It's a browser plugin that provides advanced subtitle functionality. You can have dusl sets of subtitles up, or just the original language subtitles with the option to pause and mouse over individual words for the definition.
Different languages have very different grammar, and even the best translated subtitles won't be able to handle a clever usage of the original language's grammar.
This is one of the many tradeoffs you make with translated works. You always lose something (sometimes a lot) in the translation.
