Misheard words is something that Overtone fixes. But it can't fix all, in some cases audio mix and pronunciation are so bad that it's genuinely hard even for a human in their native language to understand. Music also messes up speech-to-text models.
Unfortunately translation of (on-screen) text wasn't built into Overtone. This is something both Netflix and Disney are very aware of, and they already create multiple visual versions of content. On both platforms you can trigger a different visual language version by changing your UI language. Disney movies are most known for this: https://www.youtube.com/watch?v=FxzL7UYyAeg
They use the IMF format to transport content with "overlays" for different languages. In those languages certain frames are swapped out for a translated version. So that an EXIT sign is seamlessly translated to a SALIDA sign in Spanish for example.
Simpler way to do this is forced narrative captions. They are basically a separate captions track to only translate stuff like the on-screen sign you mention. This is combined with regular captions. Netflix turns them on by default I believe, and on Apple TV+ it's called "auto" captions.
The core problem is that AI isn't yet able to do everything. There's a race to the bottom going on for translation companies and things won't get better until AI gets better probably. Companies like Netflix and Disney still spend good money to get high-quality captions, but smaller ones don't unfortunately. Best thing for you to do might be to message the provider so they at least know that people are unhappy.
I’ve tried looking for instances of specific movies or shows doing this sign translation thing but haven’t found anything other than some Disney stuff. Do you know if this is used anywhere in non-animated film? Or if anyone puts translations near the sign, styled to look similar, rather than replacing it?
Netflix does this as well, they did it for a Mexican show called Ctrl-Z: https://www.youtube.com/watch?v=amyCefA5PfM
And here's an example of the Warner Bros. movie Demolition Man, where they localized Pizza Hut product placement outside of the US: https://www.youtube.com/watch?v=mn-PD4VuG8g (even the logos on the door were paintbrushed away, there's more clips to be found on YouTube btw)
Both Netflix and Disney push development of the Interoperable Master Format (IMF). I haven't seen visual localization happen outside of those two.
The John Wick movies have "expressive" closed captions, which as far as I know they've done in both English and Spanish. Other languages get forced narrative subtitles, sometimes with and sometimes without the English burnt-in captions.
And about the future: GenAI could definitely help localize parts of the video. Wouldn't surprise me if it's been used for this already. Combine that with IMF and you've got a solution that can instantly be adopted in the high-end production world.
