Video as cover

Background video shouldn’t be generic decoration. It has to set tone, rhythm and material: in five seconds, you should know whether the site is about creative direction, product, architecture, culture or technology.

When yes

• Real movement in the work. If the project lives on camera, looping it speaks the piece’s own language.
• Atmosphere that’s hard to freeze. Some brands are held together by a feeling (shifting light, material, human presence) that a still photo flattens.
• Clear differentiation. If your competitors are uniformly photographic, a well-made video already sets you visually apart.

When no

• Inert product. Static type, architecture without people, fashion stills. A good image usually says more.
• Slow connections or old phones. If part of your audience is off broadband, video adds friction your conversion can’t afford.
• No poster. Without a representative frame loaded instantly, the hero flickers or sits black: worse than no video at all.

Working rule

The piece should be short (8-15 seconds), silent, carefully compressed and paired with a decent poster image for browsers that defer or block autoplay. If served by Vimeo or YouTube, don’t load it until media consent is granted — the hero can live off the poster without losing presence.

A cover video is worth exactly what it costs to produce well. If it’s not going to receive that care, a strong photograph always wins.
