Keep interactive video-ad requests subordinate to the player

Identify the authority boundary

SIMID 1.2, checked 7 November 2026, constrains creative requests through player capabilities. Its resize request covers both media and interactive surfaces, rather than just the overlay. The relevant specification sections describe request resolution and rejection; they do not prove that a particular player implements every capability. Verify the actual supported integration before designing around it.

Sketch three objects: the underlying video, the interactive layer and the surrounding publisher experience. Assign an owner to each. Then list proposed creative actions in ordinary language, such as opening a detail panel or changing the available presentation area. Ask which action is entirely internal to the creative and which needs the host to participate. A designer’s storyboard is a statement of intent, not evidence that the host delegated authority.

Turn proposed behavior into a capability contract

Build a row for each host-dependent action with its declared support, request, expected response and acceptable fallback. Keep a negative row for a capability the integration does not permit. The accepted creative should remain understandable in that row, without pretending the requested change occurred or repeatedly issuing requests to wear down a restriction. A fallback may simplify the design; it must not bypass player controls.

Use a supplied fictional capability profile and have the implementer identify the corresponding documented fields. Avoid embedding real session identifiers or copied live messages in the worksheet. Record whether the evidence is a specification promise, an implementation declaration or an observed result. These are different kinds of support. A feature present in the standard can remain unavailable in the actual placement, and an attractive isolated mockup cannot resolve that difference.

Accept the relationship between the two surfaces

Draw the intended video rectangle and interactive rectangle before and after a proposed layout transition. Mark the product area that must remain visible and the controls that must stay aligned with the relevant picture. Compare those marks with a supplied successful-transition capture. This geometry sheet makes a mismatch concrete: the button may move correctly while covering the demonstration it is supposed to explain.

Next review a supplied rejection fixture. The unchanged composition must still communicate the offer and provide an honest interaction path. Do not accept a state in which the creative labels the presentation expanded while the combined picture remains in its earlier arrangement. Distinguish geometry disagreement from an intentionally different creative layout: the producer needs the approved relationship between the surfaces, not identical dimensions chosen merely for convenience.

Close the contract without taking over the player

Have the creative and player owners reconcile every unsupported or inconsistent row. If the intended experience depends on a capability the placement lacks, simplify the proposal or choose a separately approved compatible placement. Do not infer permission from the fact that a browser script could attempt another route. Preserve host navigation, playback and user-control restrictions throughout the decision.

Retain the capability profile, surface drawings, response evidence and creative version as one acceptance packet. State which behavior was demonstrated and which remains unavailable. Keep this review separate from generic autoplay testing, audience measurement or an assurance that the ad will deliver. A later player or layout change requires review of affected contract rows. This lesson performs no real request, configures no permissions and publishes no creative; it specifies evidence for the authorized implementation owners.

Make the reasoning concrete.

A fictional product film proposes enlarging a detail interface during a demonstration. One supplied placement profile declines the transition; another accepts it, but the detail controls obscure the machine feature being explained.

The team returns the proposal for a compatible composition and an honest declined-transition state. It does not seek broader host permissions through the test.

Use these prompts in your own notes. Nothing is submitted from this page.

1. Objects

   Who owns the video, interactive surface and surrounding experience?

2. Capability

   What evidence establishes support for each proposed host-dependent action?

3. Request

   What outcome is expected when the host declines?

4. Geometry

   Which picture features and controls must remain aligned and visible?

5. Acceptance

   Which exact player profile and creative version demonstrated the agreed relationship?

Watch for the wrong conclusion.

• Treating a storyboard as delegated host authority.
• Approving the overlay without the underlying picture.
• Making a declined state claim that a transition succeeded.
