Subtitle Factory

Subtitle Factory is a simple and intuitive app for adding and editing subtitles in video files (MOV, M4V or MP4). It saves subtitle data directly into video files — without burning subtitles into the image. This offers several advantages: • Subtitles can be turned on or off • Subtitles can be edited or removed even after saving • Multiple subtitle languages can be included, allowing users to switch languages in supported video players. Subtitle Factory does not re-encode video or audio data. Only subtitle data is updated, so there's no loss in video or audio quality, and saving is fast — even for long videos. Subtitle Factory adds, edits, and saves subtitle tracks defined in the QuickTime/MP4 video file specification. These subtitle tracks are supported by many video players, allowing subtitles to display during playback, including: • QuickTime Player • Music and TV apps on Mac, iPhone, and iPad • Other third-party video players that support the subtitle track defined in the QuickTime/MP4 specification ■ Key Features • For each subtitle text: 　• Set text color, bold, underline, and italic styles 　　※ Note: Font and background color settings are not supported 　• Adjust subtitle display position • Create and edit separate subtitle tracks for different languages • Import subtitles from .srt files • Export subtitle data to .srt format 　※ Note: You cannot directly open or edit .srt files ■ Supported Formats • QuickTime movie (.mov) • MP4 file (.mp4, .m4v) But the app cannot open/play the following files. • Files that QuickTime Player cannot open • Files that require conversion or additional codec components to open in QuickTime Player • DRM-protected files such as movies or TV shows downloaded from the iTunes Store or TV app • Fragmented MP4 ■ NOTE! • Whether subtitle text styles (such as color and placement) are applied depends on the video player being used • Closed Caption tracks are not supported • As mentioned earlier, Subtitle Factory does not support burning subtitles into the video image • Please make sure to back up your files before using this app, just in case an unexpected error occurs. ■ Sample Movie Please visit the Subtitle Factory support website, where you can download a sample movie with English, French, German, Japanese, and Korean subtitle tracks created using Subtitle Factory.
