Sync your soft subtitled movies to your iPad using iTunes as you normally would.

Launch the Videos app on your iPad and select the subtitled movie you just synched.



When playing a soft subtitle movie you will see new symbol on the left of the movie controller. Use that button to reveal a popup window where you can select your desired subtitle language (if you added multiple languages).



Now you can enjoy watching subtitled movies on your iPad.



Note: You can’t change the size or appearance of the subtitles on the iPad. It’s all handled by the system. If you want control over size and fonts and such I recommend you to file a feature request to Apple.

That’s it!
