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.

Solid Piece of Software

Downloaded this program to create a .SRT file. Need to get a video up on Youtube with subtitles quickly and this did the trick.
