Re: EPUB videos

Hi Siri -

You can add video to content in ePubs just as you do in HTML5.   Captioning
can be saved to the ePub as a "vtt" file and referenced as in HTML5.  Here
is a simple markup example:

<video width="320" height="240" controls>
   <source src="https://somevideo.mp4" type="video/mp4"/>
   <p>Your browser doesn't support HTML5 video</p>
   <track src="../captions/somevideo.vtt" srclang="en" kind="captions"
label="English" type="text/vtt" default=""></track>
</video>

A VTT caption file is structured like this, where the time the caption is
going to be displayed is specified:

WEBVTT

1
00:00:00.000 --> 00:00:00.500

2
00:00:00.500 --> 00:00:03.630
Some caption

3
00:00:03.630 --> 00:00:05.560
some other caption

4
00:00:05.560 --> 00:00:07.860
some further caption

5
00:00:07.860 --> 00:00:10.200
etc.

There are ways to automate/script significant portions of the work
involved, which is too much to get into here.

I hope that helps some.  Here is more info:
