How do you combine a real demonstration with a generated product scene?

Assign a role to each layer

A real close-up can show a switch or closure operating while a generated room view explains context. Record which footage establishes the operation and which is illustrative. Keep the sources, permissions and exact variant with the edit plan. Avoid using private customer footage without the appropriate authorization.

For an illustrative desk lamp, the real insert may show its dimmer response. The generated background should not imply a measured light output or a synchronized live event. A shared color palette does not make two separately produced layers documentary evidence.

Create a layer contract

Use distinct framing or a short plain label when the origin might be misunderstood. Keep the explanatory distinction readable rather than hiding it in a long closing disclaimer.

Create only the needed contextual shot

For this finishing method, keep the authorized real footage and generated context as separately identified sources and assemble them in an external editor. Check the actual selected production route and delivered assets. Combining the layers does not verify a product claim or turn generated context into a second recording of the event.

Review whether the generated product’s controls and state match the real insert. A lamp shown switched off in one layer while the real footage demonstrates it illuminated may need explanation or a different scene.

Watch the attention handoff

At phone size, viewers should be able to see the real operation when it is discussed. Do not cover the evidence with a logo, caption or decorative frame. Review the final mix and the origin explanation at normal playback speed. A correct source can become unintelligible in a tiny insert.

Use source mixing for the broader edit and visible feature evidence for the claim. Retain the layer contract with the exported file so future crops preserve the distinction.

Fictional lamp edit: insert R-v2 records a real hand moving the dimmer under one documented setup. Background G-v1 is a generated room. Showing the room brighten exactly when the finger moves can imply the background records the same response, even if both product colors match.

Review the intended phone layout while the claimed operation is being discussed, rather than approving a large editing monitor alone. No universal insert size proves that every viewer can understand the operation. This fixture is not a filmed demonstration, an actual lamp test or a completed composition. The general ad-planning source is background only; the simultaneous-layer checklist is original editorial guidance.
