Where does your app first appear in your demo video?

Drop the video and one screenshot of your app. You get the first frame where the app fills the screen, as a timecode and as an edit for your editor. The video stays on your computer.

Example from a real video: the Can I Park Here demo, first 20 seconds at 2 frames per second.

It is a stopwatch, not a judge. It reports a time; it does not score your video. Each file trims the head of your timeline to the found frame and puts a marker there. Your editor asks you to relink the file on import.
