I sometimes watch videos from "Jiro, Just Japanese". These videos are really nice, and one of the main reasons is the subtitles.
At the top, there are Japanese captions of the Japanese audio, and on the sides, every word is translated into English with the difficulty level indicated (N5, N4, N3, N2, N1).
In the description, there’s also a PDF with each word and its timestamp, which is also very useful.
Does anyone know what tool(s) he uses?
If you don’t know the exact tool, but know another one that can do the same, that would also be very helpful.
Bonus question: is it possible to translate only N4, N3, N2, and N1 words, but not N5 words, for example?
I tried asking in the comments what tool he used, but he didn’t answer, so I’m asking here.
I personally want to use it for videos that are currently a bit too difficult for me, so I can understand them better.
