sub maker?

[donkeykog]

Is there a program that can take the subs out, so I can work on them, and then re-add them to the movie?

I have a few movies where the subs were obviously done by google trans and are pretty bad. I was watching a movie tonight and having to translate the translation in my head and I thought "Self, I wonder if I could take this movie and fix the subs?". Most are grammar problems (saying he instead of I or she) and issues of sentences not being put together properly, but give enough of the gist of what they are saying that it can be somewhat fixed.
