How to place transparent video in Webflow

Webflow’s native video backgrounds are designed for conventional rectangular footage. Transparent motion works best through an Embed element containing a standard HTML video tag. First, convert the animated WebP or GIF above. Download the verified bundle and host its WebM, MOV, and poster files on stable public URLs. Then add an Embed element where the animation should appear.

<video class="alpha-video" autoplay muted loop playsinline poster="POSTER_URL">
  <source src="MOV_URL" type='video/mp4; codecs="hvc1"'>
  <source src="WEBM_URL" type="video/webm">
</video>

Replace the three URLs with the hosted files. Publish the Webflow site before judging playback; designer preview behavior and asset URLs can differ from the live page. Test in desktop Chrome and Safari, then test on a real iPhone. The muted and playsinline attributes are important for autoplay on mobile.

Position it like a native design layer

Give the Embed element a class and control the video with ordinary Webflow layout tools. Use a relative parent when the animation must overlap headings, cards, or product imagery. Set the video to width: 100% and height: auto for responsive sizing. If it is decorative, use absolute positioning and pointer-events: none so it does not block links or text selection underneath.

Do not add a checkerboard behind the finished animation. The checkerboard is useful while inspecting alpha, but production transparency should reveal the actual Webflow design. Check light and dark sections for edge quality. If you see a dark halo, inspect the original export; the source may contain premultiplied color contamination.

For layered hero compositions, give the parent a predictable aspect ratio and clip only when the design requires it. Webflow transforms can create new stacking contexts, so check the element’s z-index relative to navigation and buttons. On smaller breakpoints, reposition the same Embed instead of duplicating autoplay videos; duplicate elements can make both files decode even when one looks hidden.

Keep the Webflow page fast and accessible

Load only the resolution you display. A 600-pixel animation rarely needs a 4K source. Include a poster and honor reduced-motion preferences by hiding or pausing the video in a Webflow custom-code media query. Avoid placing several autoplay animations above the fold. The strongest composition normally has one motion focal point and static supporting content.

Stable hosting also matters. A URL used in an Embed should not change when you replace the underlying asset. RevNex hosted embeds are built for that workflow: copy one stable URL, update the media behind it, and leave the Webflow project untouched.
