Real UI as proof
Show the product doing its job, big enough to read.
Takeaways
- 35 to 60 percent of the frame.
- The product doing the job, not just present.
- By about 40 percent of the runtime.
What it means
A film that shows the product late, or never doing the job, is a mood piece. A proof card should take a real share of the frame, cropped or tilted if you like. Under about a quarter of the frame it is a chip or an accent, not a proof.
In a RasanAI film
UI is shown as a simplified recreated mockup, never a screen recording, and sized at 35 to 60 percent of the frame by area. The first proof arrives by about 40 percent of the runtime, and at least one beat is marked core_job_demo.
