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.

Very good so far...

I occasionally add captions to videos for work but had the hardest time finding a subtitle editor that had working keyboard shortcuts and didn't have the "cross platform look". Subtitle Factory works intuitively enough that I was able to dive adding captions immediately and export the .srt file seamlessly. Time will tell how well this app holds up to regular use, but its well worth the money so far. Two things I'd like to see in the future: 1) Automatically stop the video when using the "Insert Subtitle" keyboard shortcut (currenlty have to stop the video before the shortcut will work), and 2) Add a waveform viewer to scrub through the video and more accurately align the audio with the subtitle text.
Basic, but well-built app; perfect for the price

I needed a basic app for adding subtitles and didn't really like the look of the cross-platform open source stuff that seemed to be common, so I bought this to give it a shot. I was quite impressed it's a well-built, native app that has everythign you need for basic subtitle editing.It also seems to be well-supported as it was very quickly updated for Mojave, even including dark mode.It seems to have solid support for multiple tracks and metadata, but I haven't used it extensively. I also didn't actually edit the video file; I just exported the SRT and then hard-coded with ffmpeg myself separately.
Limited file type playback and scrolling abilities

Seems to only works with mov, mp4 and m4v files, not wmv or avi.It's text window doesn't update as you scroll the video.The video will however follow your scrolling through the text window.
Easiest way to create subtitles

Subtitle Factory makes it Incredibly easy to type and insert subtitles. Be sure to read the brief user guide at the Tranquility Base website; only took a minute or two to get up and running. A powerful yet simple app on MAS that's just 2.4MB? Yuji is a wizard.
