Q1: Screen Recording
"I'll turn that into a polished demo! First — where's the screen recording?
(provide the file path, e.g., ~/Desktop/recording.mp4)"
Wait for response. Verify the file exists.
Q2: What does the app do?
"Give me a quick overview of what this app does and what the recording shows.
(e.g., 'It's a task management app. The recording shows creating a task, setting a due date, and marking it complete.')"
Wait for response. This context dramatically improves the voiceover script.
Q3: Device Frame
"Should I wrap it in a device frame?
