A product video can look good in a presentation and still feel awkward on your landing page. The visitor might scroll past before the useful part arrives, the interface might be too small to read, or the explanation might depend on audio they never turn on.
Before you buy a template, brief an agency, or ask an AI agent to make the video, decide how it will fit into the page. You're commissioning something that has to work beside a headline, a button, and the rest of your product explanation. Here's how I'd turn that into a useful brief.
Choose the question the video answers at that point on the page
Read the text immediately above the proposed video and ask what someone would still need to understand. If the headline says your product turns receipts into expense reports, the next useful thing might be seeing a receipt become a report. A tour of the settings menu would answer a different question.
That example is a fictional product, not a customer result. The point is to give the video a specific job. Write it as a question, such as 'What do I get after I upload a receipt?' Then decide what would count as an answer on screen.
If the question only makes sense after someone reads a feature section, put the video there. You don't need to move it into the hero just because that's the most prominent space. Keep the page's main explanation and next step understandable for visitors who never watch.
Decide whether watching is optional or expected
For a detailed explanation, I'd usually give someone a play button and let them choose when to watch. Show a useful still image before playback and name what the video covers. 'See how receipt review works' gives them more context than an unexplained triangle over a logo.
A silent moving preview can work when the action is understandable without a setup. But consider what happens if someone arrives halfway through it. If they see a finished report without seeing the receipt, will they understand what changed? You may need a persistent label or a simpler sequence, rather than a faster edit.
Don't build the page around sound starting automatically. Browser autoplay rules can block audible playback; MDN explains the distinction between audible and muted media. Provide a sensible still state and usable playback controls so the explanation doesn't depend on autoplay succeeding.
Make the composition fit the actual space
Ask whoever owns the website for the video container's size on desktop and mobile before production starts. A wide dashboard can look readable in a full-screen preview and become a collection of tiny labels when it sits beside a headline.
For the fictional receipt tool, the important comparison might be the original total and the total in the resulting report. Those two values need enough space to read. The account menu and unrelated report columns probably don't. Focus the view on the evidence without changing the values or implying an action the product doesn't support.
Put a rough still into the real page layout before animating everything. If the key detail is already too small, motion won't fix it. You might need a closer composition for mobile, a different placement, or a simpler example. Decide that while the scene is easy to change.
Include the supporting files in the production brief
The finished movie is only part of what the website team needs. Ask for a poster image that represents the explanation, the agreed desktop and mobile treatments, and a written description of what the visitor learns. Make clear whether you need an editable project for later changes, too.
If the video includes speech or meaningful sound, plan captions. Important information shown only visually also needs an accessible explanation. W3C's media guidance covers captions, descriptions, transcripts, and accessible players; which pieces you need depends on the content. Plan them before recording narration so they aren't awkward additions at the end.
Name the person who checks the final caption text against the product. Automatic transcription can still get a feature name wrong, and a transcript that only repeats the narration may leave out the result someone is supposed to see.
Agree on loading behavior with the website owner
Tell the developer whether the video is visible immediately, farther down the page, or opened after a click. Those are different loading situations. Ask them to check the page with the actual export instead of assuming the file that looked fine on your laptop will behave well for every visitor.
For a video that waits for someone to press play, web.dev documents using a poster image and preload settings to avoid downloading the whole video before it's needed. It also discusses treating an immediately visible poster differently from media farther down the page. There isn't one loading setting you should paste onto every placement.
Agree on how much detail the export needs to preserve, then inspect any compressed version. If compression makes the receipt total unreadable, the smaller file has lost the thing the scene was meant to explain. Keep the page's text and action available while the player loads.
Use a brief that includes the page, not just the film
Here's a hypothetical brief for the receipt example. Replace the workflow with something you've checked in your product, and attach the actual page layout so the person making the video can see where it belongs.
Placement: Beside the receipt-to-report feature explanation. Viewer question: What happens to a receipt after I upload it? What to show: The supplied example receipt, the actual review step, and the resulting expense report. Preserve the amount and field labels. Playback: Click to play with controls. The poster and nearby text must explain the purpose before playback. Viewing sizes: Use the attached desktop and mobile page layouts. Flag unreadable details before finishing the animation. Deliverables: Final video, poster image, captions if there is speech or meaningful sound, written explanation of important visual information, and the agreed editable project. Review: Product owner checks accuracy; website owner checks playback and loading in the page. Do not imply that review or approval happens automatically.
If you're using AI to make the scenes, include these constraints in the request and check them in the result. A confident-looking draft doesn't tell you whether the report amounts, review step, or mobile framing survived the generation correctly.
Check the published page before calling it finished
Open the page on a phone and a desktop, with sound off first. Check the poster, start playback, pause it, and try the controls with a keyboard. Make sure captions stay readable and the page's main button is still easy to find. If the video moves automatically, check that visitors can stop the motion and that your reduced-motion treatment behaves as intended.
Then ask someone unfamiliar with the workflow what they think the product did. If their answer includes an automatic approval you never intended to promise, fix the scene or its explanation. That's a more useful reason to revise than simply wanting the video to feel more exciting.
You can evaluate whether the page helps visitors take the intended next step after publication, but a video doesn't come with a guaranteed conversion increase. First make sure it answers the question you commissioned it to answer, in the place people will actually watch it.
