Video funnel in webflow

I recently saw from clickfunnels and Im wondering if it would be possible to build similar “squeeze video player” that would only allow playing the video after submitting an email inside Webflow itself.

Webflow does not have its own video player. For media embeds they use Embedly which the generates the standard YouTube, Vimeo, Wista, etc. player.

Wista supports in-video gating, they’re essentially the pioneers of this.
Compare the pricing, features etc with Voomly if you’re considering that.

If you’re a developer, you could also roll your own with javascript and overlays and back-end it with e.g. YouTube as a video source, but it would be a fair bit of work to create that.
