Dynamic Abstract Motion Banner Video

I want a high-energy banner video that instantly grabs attention the moment a visitor lands on my homepage. The piece must rely solely on graphic motion—no live-action footage—and follow an abstract, dynamic style that feels fluid, modern, and continuously moving rather than a simple start-to-finish play-through.

The animation should:
• Run in a perfectly seamless loop (10–15 seconds is ideal, but I’m open to your recommendation).
• Stay light enough in file size for fast page loads while retaining crisp visual quality.
• Feature bold shapes, fluid transitions, and kinetic pacing that reinforce an innovative brand feel.

Deliverables I need from you:
• Storyboard or style frames for quick approval.
• The final banner video in MP4 and WebM formats, optimized for web.
• Source project file (After Effects, Blender, or similar) so I can make minor tweaks later if required.

I’ll provide brand colours, logo assets, and any copy that should subtly appear in the animation once we start. Let me know your preferred toolset, approximate turnaround, and any clarifying questions so we can keep momentum moving.
