Viral format breakdown
Comment Reply Video Guide
Use one audience question as the editorial brief, then answer it with evidence before adding context.
Updated 2026-10-26
Why this format works
- “Does it work on a deep sofa?” creates a specific open loop instead of a generic announcement.
- Use the tool across the deepest section in one pass turns the central claim into an observable action.
- Show the collected debris and state the limitation resolves the opening and gives the viewer a natural next step.
Second-by-second structure
| Time | Beat | Shot | On-screen text | Voiceover |
|---|---|---|---|---|
| 0–2s | Hook | Immediate close framing on the situation | “Does it work on a deep sofa?” | “Does it work on a deep sofa?” |
| 2–6s | Show | Pin the question on screen and measure the cushion seam | Watch the setup | Here is the part that matters. |
| 6–13s | Prove | Use the tool across the deepest section in one pass | The proof | This is what changed my mind. |
| 13–17s | CTA | Show the collected debris and state the limitation | Try this approach | Use this structure for your own product. |
Pacing reference: 30 cuts per minute, roughly 3.4 seconds per shot. Voice: Responsive, concise, candid. Audio: Low-key instrumental under clear dialogue. CTA: Invite the viewer to save the method, inspect the product, or try one relevant step.
Ready-to-use example script
“You asked whether this reaches into a deep sofa, so I measured mine first. The nozzle gets past this seam without removing the cushion, and one slow pass picks up what the wide head missed. It will not fit under the fixed back panel, so I use the narrow tip there. Send the awkward spot you want me to test next.”
Remix this format with Kopi
- STEP 1Give Kopi your product brief and ask for a comment reply built around ““Does it work on a deep sofa?”.”
- STEP 2Review the proposed hook, timed scene list, spoken lines, and credit estimate before approving generation.
- STEP 3After the first cut, request a focused revision to the weakest scene while preserving the beats that already work.
Good product fit
- Products with recurring objections
- Tools with visible tests
- Feature-rich apps
- Community-led brands
Poor product fit
- Invented comments presented as organic demand
- Questions that require professional advice
Planning and review notes
A comment reply should preserve the exact question that shaped the test. Pin “Does it work on a deep sofa?” before introducing the nozzle, then measure the seam so “deep” has a visible meaning. The answer begins with the demonstration, not a greeting or brand history. If the prompt is a representative FAQ rather than a real public comment, label it that way instead of simulating organic demand.
A candid limitation makes the response more useful. The wide head reaching the cushion seam does not prove it fits beneath a fixed back panel, so switch to the narrow tip and explain why. The collected debris can support the cleaning demonstration, but avoid implying sanitation or allergen removal without evidence. Invite another awkward location to test only when the team can answer future requests under the same transparent conditions.
Frequently asked questions
Can a brand write its own comment-reply prompt?
Yes, but present it as a common question or FAQ rather than fabricating a named customer comment and engagement history.
Should the pinned comment stay visible throughout?
Keep it through the hook and early test, then remove it when it would cover the product detail needed to understand the answer.
What makes a reply more trustworthy than a standard demo?
The question defines a falsifiable test, and the video answers that narrow concern while acknowledging what the test does not establish.
How should follow-up questions be selected?
Choose recurring, demonstrable objections that can be tested safely rather than requests for medical, legal, or professional conclusions.
