I use the language reactor browser extension (for Chrome / Edge). That’s good enough for me, the important features are: it can auto-pause after each subtitle, allows repeating the audio matching the current subtitle and allows revealing the text on demand. I don’t use the translation and don’t pay either. Ideally one remaps the keys, I’m thinking about getting a primitive bluetooth remote for this purpose. But language player looks good as well, shame that they request payment after 1 minute of video already.
“shame that they request payment after 1 minute of video already”. Yes, I used it a bit when it was free 1-2 years ago. Back then I thought it was too good to be free. So, I am not surprised they switched to a pro mode.
