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.

Easily add SRT to MP4 ,

Quick and easy converter

I had to add an SRT (subtitle) file to my short MP4 video and it took less than a minute total. Did the job I needed it to do!

Buggy early release that does not work as stated

This is a terrible program. It simply stops responding when you ask it to do what it's supposed to do - add a subtitle track to a video - and I have had to force quit each time I try to use it. Also, the subtitles aren't aligned with the video even thought the SRT clearly shows when the subs are supposed to appear. Waste of $5, I advise you not to put yourselves through this pointless exercise.
