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.
