Does the first 3 seconds show the real product — not a logo, not a tagline?
The viewer decides in the first 2–3 seconds whether to keep watching. Open on the product doing something meaningful, not on branding, atmosphere, or a founder talking. If second 1 is a logo animation, you have already lost a meaningful share of your audience before they understand what you built.
Fail condition: logo, tagline, or atmosphere only in first 3sIs the on-screen text legible at mobile resolution?
If your video contains product UI text, that text must be legible at 390px wide on a mobile screen. AI-generated video cannot render legible UI text as of June 2026 — this is a confirmed, unsolved limitation across Kling, Seedance, and Veo 3. If the on-screen text is blurry, garbled, or hallucinated, the video is not showing your product. It is showing an AI approximation of a product. For legible UI text: code-based rendering (Remotion) is the only reliable option.
Fail condition: UI text unreadable at mobile size, or AI-hallucinatedIs there one clear claim in the first 10 seconds?
What does your product do, for whom, and why does it matter? This claim should be statable in one sentence and visible or audible within the first 10 seconds. If you need to watch more than 10 seconds to understand what the product is, the video is not launching your product — it is describing it. The launch film's job is to earn the click to the demo or the product page, not to replace them.
Fail condition: value proposition unclear after 10 secondsIs the video 60 seconds or shorter?
For a launch post on X, LinkedIn, or Product Hunt, 15–45 seconds outperforms longer formats in completion rate. If your video is longer than 60 seconds, it is a demo, not a launch film. The launch film earns the watch for the demo — it is not the demo. A common mistake is treating the launch video as a walkthrough. Walkthroughs live on the product page after the launch post earns the click.
Fail condition: runtime over 60 seconds for a feed-first postDoes it work with the sound off?
Most launch videos on X and LinkedIn are watched without audio on the first pass. On-screen captions, legible product UI, and a clear visual progression must carry the full story silently. If the video requires audio to make sense, it will fail silently in most distribution contexts. Test this yourself: mute the video and watch it through. If you do not understand what the product is and why it matters, the silent version is not working.
Fail condition: muted watch-through leaves the product purpose unclearIs there a single, clean CTA at the end?
The launch video's job is to earn the click to your product, your waitlist, or your pricing page — one destination. If the end card has three different actions (follow, sign up, visit the site, read the thread), it will produce fewer clicks than one clear one. Pick the most important action for this launch and eliminate the others. The viewer who wants the other options will find them on the landing page.
Fail condition: more than one CTA, or no CTA at allIs the product UI captured at 2x or 3x resolution?
A screen recording captured at 1x resolution on a 1080p display looks blurry on retina screens and immediately signals “rough demo” rather than “polished launch.” Capture your product UI at 2x or 3x using Screen Studio, CleanShot at 200% zoom, or by recording on a retina display. The resolution difference between a professional launch video and a demo recording is often nothing more than capture settings — it costs nothing extra.
Fail condition: UI appears blurry or soft on a retina screenDoes your launch video look different from a raw screen recording?
If someone could replicate your launch video by opening QuickTime and pressing record, the video is not differentiated from a raw demo. Motion design, kinetic typography, product reveals, and cinematic transitions are what separate a launch film from a walkthrough. If your video looks like a screen recording with music added, it is doing the same work as a screen recording — which means it is not converting at the rate a keynote-grade launch film would.
Fail condition: indistinguishable from a raw screen recording + background musicScored fewer than 6 passes?
That is where the launch is leaking.
Most AI startups ship launch videos that fail at least 3 of these 8 checks. The most common failure points are UI legibility (check 2), the 3-second rule (check 1), and differentiation from a screen recording (check 8). Each one is a production decision, not a budget decision — but fixing all three without motion-design expertise typically requires a studio.
Common questions
Frequently asked.
For a product launch post on X, LinkedIn, or Product Hunt, 15–45 seconds outperforms longer formats in completion rate. 60 seconds is the outer limit for a launch film. Anything longer is a demo or a walkthrough — which serves a different purpose and belongs on a product page or in a follow-up thread, not as the launch post itself.
2x or 3x resolution, using Screen Studio, CleanShot at 200% zoom, or a retina display. A 1x screen recording captured at standard resolution looks blurry on retina screens and immediately reads as a rough demo. Capture settings alone account for a large share of the perceived quality difference between amateur and professional product launch videos.
AI-generated video can add atmosphere (environments, light, abstract motion) but cannot render your actual product interface legibly. As of June 2026, this is a confirmed limitation across Kling, Seedance, and Veo. If your product is software, the launch video must show the real interface — which requires code-based motion graphics (Remotion) for the product UI sections, not AI-generated footage.
A launch film is 15–45 seconds, designed to earn the watch and the click. It shows what the product does and why it matters, in a format built for the feed. A product demo is 2–10 minutes, designed to teach someone how the product works once they are already interested. The launch film earns the audience for the demo — it is not the demo itself. Confusing these is the most common launch video mistake.
