Description

Inject subtitle tracks, chapter markers and metadata into your movies and TV-shows. The perfect companion app for your iTunes library and all your Apple devices, like the iPhone, iPad, iPod, Apple TV and Mac.

iSubtitle takes full advantage of Apple's soft subtitle technology. The subtitle tracks are resolution independent and rendered in real-time as you watch the movie. Subtitles are always displayed at the best quality your device can perform. There are support for multiple languages in the same movie file and you can even switch language on the fly as you watch. The export and metadata tagging is fully automated so you don't need to tweak a lot of parameters to get your movie into iTunes with beautiful tagging and artwork.
