A landing page video for a v0 generated app has to answer a question the tool itself does not settle: how much of what looks finished on screen is actually wired up to do something. v0 is built around producing interface, meaning React components and layout styled with something like Tailwind, and a generated screen can look completely finished while the button in the middle of it does not yet call anything real. A landing page video that shows that button being clicked, with a result implied that the app cannot currently produce, sets an expectation the product breaks the moment a visitor tries it themselves.
This is different from the concern on a platform where the generated output usually includes working backend logic by default. With a v0 build, the honest first step before recording anything is to check, screen by screen, which interactions are cosmetic and which are real. Once that is settled, the video can show exactly what the app currently does, which is a more defensible foundation for a landing page than a video that outruns the product.
None of this means a v0 build is less capable than one produced elsewhere. It reflects how the tool is commonly used: many builders start with v0 specifically to get the interface right before connecting real data or logic, which is a reasonable order to work in. The landing page video just needs to reflect wherever that process currently stands, rather than assuming the interface and the logic behind it always finish at the same time.
