Re: [dev] Writing subtitles for videos

Background: a close friend is doing subtitling for $, usually for local
film festivals. One festival often means dozens of movies to be
translated and subtitled. Most people doing this are freelance
translators with limited technical background.

No, this is beyond stupid. Try this when you have dozens of hours of
video to subtitle, on a deadline. You want this activity to be as
streamlined as humanly possible. There's no room for philosophy here,
the people doing this are already tired.

The current de-facto state of the art is to hit a key to show-next/hide
the subtitle while the video is playing. This can be done live while the
film is being displayed at a theater, or pre-recorded (possibly with
time-stretched playback).

Now this is an interesting idea and I think extending existing software
with this functionality would make it somewhat more usable.

Any improvement that takes away a part of the manual labor would be
awesome. Using machine learning, or speech recognition, to auto-suggest
subtitle timing? Hell fucking yeah, that would seriously rock.
