Re: [dev] Writing subtitles for videos

WebVTT format is more complex than I would like and also not fully
implemented on any browsers, as far as I can tell, so I use a small
subset that is very simple.



The following section is most of the parsing of my bespoke formats for
timings and texts. It references lots of other functions in the library
of interest that all do very little, so it might be very tedious to
read. The parsing of these files is simple enough that I did not give it
its own function; this passage is complex because it also handles build
dependencies, user interface concerns, and concatenation of subtitles.
https://thomaslevine.com/scm/langrompiloj/artifact?ln=72-102=a370f5205509f123

In summary of the above, I combine a timing file and a
named-for-a-language text file, and I come up with a sequence of
Subtitle objects, where a Subtitle contains a language, a list of times,
and a list of strings.

I implemented two different WebVTT formats that dump the Subtitle
sequence. I wanted to use the webvtt_karaoke, but I couldn't find any
browsers that supported the karaoke feature, so I am using
webvtt_replace.
https://thomaslevine.com/scm/langrompiloj/artifact?ln=6-31=42a903bd25efb0b0



Fortunately, the input format and data structure are simple enough that
you can probably ignore everything I discuss above. In my prior email
I referenced this timings file
https://thomaslevine.com/scm/langrompiloj/artifact/49ddb891f1f0b6fd

and these two text files.

Using the files and the corresponding video as inputs, I arrive at the
these WebVTT files as outputs.

https://thomaslevine.com/scm/langrompiloj/artifact/49ddb891f1f0b6fd

Texts for the subtitles are stored in other files, one file per
language. These files have one line per cue, so they have one fewer

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.

Re: [dev] Writing subtitles for videos

2017-08-31 Thread Thomas Levine 
As Felix pointed out (and I had not previously realized), the subtitles
depend mostly on the audio, and the video can largely be ignored.
I thus think it has relatively little to do with blind.

I had looked at mpv and came upon the annoyingly close but still
unhelpful watch-later feature. I considered whether it was possible to
implementing my proposal with just edits to input.conf and whether it
was worth using libmpv, but had not considered lua scripts. A Lua script
indeed looks promising.
https://gist.github.com/Hakkin/5489e511bd6c8068a0fc09304c9c5a82
https://github.com/thebombzen/scripts/blob/master/src/markchapter.lua

It still seems a bit messy, (Perhaps a scripting language could be
avoided entirely if the mpv configuration were written in C.) but this
will probably satisfy me for now.

I'm not planing to do subtitles, I want to keep it purely
video. However, it's in the todo-list to make a simple
graphical tool for finding frames. It will have video and
audio playback, keyframe listing, and maybe waveforms, as
well as timestamp and frame number. So it will be useful
as an alternative to the ffplay part.

I haven't editted a lot of subtitles, but for sound synchronization, a
waveform is extremely useful. Instead of hitting a button when you hear

[dev] Writing subtitles for videos

2017-08-31 Thread Thomas Levine 
I want to write some subtitles for some videos. I found several subtitle
editors through web searches, and their documentation doesn't make them
look very good. What's more, I haven't managed to install any of them
properly, which is both inconvenient and further indicative of suck.

I think that most of what I want could be accomplished by having a video
player that writes the current time somewhere (like a file) when I press
a particular key. I would play the video until I get to the position
where I want to start or stop a subtitle, then I would press the key,
and then I would copy that time to the subtitles file.

Another helpful feature would be to reload the subtitles file without
changing the current time; this way I could review the subtitles more
quickly.

Do any video players already do this? Or, does anyone have other
recommendations about the editing of subtitles?
