Why does the Peek screen recording not work properly?

I have tried using Peek to make screen recordings. When I finished the recording and click back on the Peek icon in the bottom right of my screen the file I recorded appears there but it is shaded out and has a loading animation on it and it says 'Processing'. Eventually this stops after about a day or so and then when I click view in folder it does not work. When I click view in articulate it works. Seems like this application has not been fully finished and could work faster.
