How do you translate french movie in english or Hindi?

Trying googling the name of the movie in French or English followed by the Words "French subtitles" (or Hindi).

It should return a list of sites offering such subtitles. Many are spam, but there's a few safe ones.

Try "French .srt subtitles" to exclude file formats such as ".sub", or try "sous-titres français" if "French subtitles" does not return any hit.

Once you have the .srt file, copy it into the same folder where you have the movie file, with the exact same name as the movie file, except for the ".srt" file extension (instead of .avi/.mkv/.mp4 for the movie itself.)

If you play the movie with a media player such as VLC, the subtitles will load automatically if they have the same file name. Or you can load the subtitles file from the player's menu.

If your movie is in DVD format, you'll need to rip and convert it first.

.srt files are small text file, so it's easy to check the content in Notepad.

.sub files are subtitles in graphic format, the format used in DVDs, so they are much bigger and almost no players support them.
