Check the file and the story
Is this product demo ready to test?
The browser can read the technical facts. You answer the eight questions that require a real person to watch the demo.
Drop one app demo here
MP4, MOV, WebM, and M4V files work best. The file is inspected on this device and is never uploaded.
Local-only check. No video upload or account required.
Review what the file cannot decide for you
Not sure is a useful answer. It keeps the item in your action list instead of pretending the demo is finished.

Keep the action and result together
A tap without a result feels unfinished. A result without the action can feel unearned. Let the viewer see both.

Common questions
Product Demo Readiness Checker FAQ
Do you upload or save my product demo?
No. The file stays on your device. Media Bunny reads its technical details locally, and your checklist answers are not sent to an API or analytics.
Why do I need to answer questions after choosing a video?
The technical checks can read the file, but only you know whether the most important screen is easy to understand, the outcome is honest, and every piece of private data is hidden. The checklist makes those decisions explicit.
Does a landscape demo automatically fail?
No. Wide desktop demos can be useful source footage. The checker calls out the shape without failing the whole idea, and ClipStitchr's paid workflow can place the full screen over a vertical background or use guided zooms.
Are the duration ranges official platform requirements?
No. The suggested ranges are simple planning guides for a first creative test. They are not ad-network limits, media-buying advice, or a promise that one length will perform better.
