[Athen] captions for ios devices

[Ken Petri]

Hi Dean,

The Handbrake method works just fine. But if you have a Mac iSubtitle gives
you more options.

Here's the too-long URL on how to do this with Handbrake:
https://carmenwiki.osu.edu/display/10292/DIY+Captioning+Techniques#DIYCaptioningTechniques-AddingCaptions%28Subtitles%29toMP4VideoforUseiniTunesorVLC

A short URL to the entire DIY Captioning Techniques page is:
http://go.osu.edu/diy-captioning

Other good info in this page as well. The info about how to add an audio
description track is forth-coming. That technique does, however, require
QuickTime Pro....
