A background video should support the message without becoming a condition for reading it. Ask the agency to show the hero section when the clip plays, when it cannot play, and when the visitor prefers less motion.

SECTION 01
Choose between decorative motion and information
Decide whether the video establishes atmosphere or explains something the visitor must learn. An informative demonstration needs an accessible playback experience and equivalent information where appropriate. A decorative hero can leave the page fully understandable without playing. MDN documents video elements and playback behavior; W3C's pause guidance addresses moving content that competes with other content.
Ask who supplies the licensed clip, how the crop changes across devices, and how large the transfer will be. A generic stock scene must not imply that the people shown are your employees or that the setting is your office. The development scope should include the static poster and disabled-motion state, not treat them as unfinished versions of the design.
SECTION 02
Illustrative example: a software agency hero
Imagine a software agency chooses a short clip of a person working at a computer. The headline explains the actual services, while the clip remains softly behind it. A bright frame makes the white text unreadable halfway through the loop. A static screenshot approved at the beginning did not reveal that problem.
Review the entire clip with the real text and buttons. Use a stable overlay or another treatment that preserves contrast across frames. If motion is paused or unavailable, the poster should still look intentional. This is a design example, not a claim that the stock footage records the agency's own work. Avoid embedding essential service labels into the video itself.
SECTION 03
Test control, loading, and fallback together
Ask the agency to demonstrate pause and resume with keyboard and touch. A pause state should remain useful while the visitor continues navigating. Respect reduced-motion preferences and ensure the site remains complete if autoplay is blocked. Do not make the inquiry button wait for the clip to finish downloading.
Acceptance should cover a slow connection, missing video source, portrait screen, browser zoom, and movement preferences. Check whether the clip continues consuming resources after the relevant area is no longer useful. The tradeoff may favor a still image on some pages; that is an implementation decision, not a design failure. Document how future editors replace the asset without dropping the poster, controls, or readability checks.
SECTION 04
Frequently asked questions
Can we rely on autoplay?
No. Browsers and user settings can prevent playback. The static state must communicate the complete message.
Does a blurred background guarantee readable text?
No. Brightness and contrast can still change throughout the clip. Review all frames with the actual copy.
Should a product tutorial play behind a heading?
Usually not. Important explanations belong in a player or content area where users control playback and can access equivalent information.
