I have a .mp4 movie clip on my iPhone, and I also have its corresponding .srt subtitles file. Is there any way to get the subtitles to display on the iPhone? Do I have to combine these two files and make a .mp4 that contains the subtitles as part of its visuals or something?
You have to combine them (unless there's a JB app). I've been recommended this before but never got around to using it: http://www.bitfield.se/isubtitle/index.html
