Looks interesting, why would somone sell before launch?
Auto-generating the zoom effects from actual interactions is the part that saves the most time — manually keyframing zooms in post is exactly the tedious step that stops people from polishing their demos. Can you tweak or delete an individual auto-zoom afterwards if it lands somewhere you didn't want? The aspect-ratio and cursor controls are a nice touch too for turning one recording into both a landscape and a vertical cut.
really good idea Best of luck with the launch!.....This solves several job application tasks in one place
