Thank you @tgwaste for making that feature edit!
Unfortunately, I'm still finding a way to screw things up. I downloaded capto 0.4, unzipped into ~/Dropbox/RevProj/Capto/, then updated the IP and set the new ffmpeg location. I'm able to update the listings, see episode info, etc., but when I run an export it instantly finishes with 0% complete.
Question, should the ffmpeg path be specified as the folder or the direct path when run in terminal? E.g., /Dropbox/RevProj/Capto/ or /Dropbox/RevProj/Capto/ffmpeg?
After a couple of ffmpeg attempts, I deleted everything and ran through the install process fresh, still no luck. Lastly, tested in my original install location /Downloads/ and the export works perfectly. So, not sure what I can do to get Capto away from my original download & test location.
Definitely hit a dead end, thought the ffmpeg adjustment was the trick.
