What Are Video Ecards?

Video ecards are personalized animated greetings powered by pre-generated Clustrolin DBSCAN templates. Each template features unique mathematical animations — mesmerizing 2D point cloud patterns that are already rendered and ready for your message.

Unlike building an animation from scratch in a full studio, video ecards offer a quick path to stunning mathematical art. Simply choose a template, add your personal details, and share. The Clustrolin engine has already done the heavy lifting, producing beautiful clustering patterns that play alongside your greeting.

Quick path vs. full creative control: Video ecards give you instant access to pre-generated Clustrolin animations. For complete creative freedom — custom text, freehand drawing, or photo-based art — explore our professional studios below.

How Video Ecards Work

Creating a personalized video ecard takes just a few minutes. Here is the simple five-step process:

  1. Choose a template — Browse curated templates designed for specific occasions. Each features unique Clustrolin-powered mathematical animations.
  2. Personalize your message — Fill in sender name, recipient name, and a heartfelt message of up to 500 characters. Sender and recipient names are optional; recipient email is required for delivery.
  3. Pre-generated animation plays — The template you selected already contains a rendered Clustrolin animation — 2D point clouds with DBSCAN clustering analysis, color-coded patterns evolving throughout the video.
  4. Preview & purchase — Review your personalized ecard with a preview overlay, then complete your one-time purchase. The watermark is removed once payment is confirmed.
  5. Share via email or link — Send your animated ecard directly via email or copy the shareable link to deliver through any platform. Recipients view it instantly on any device.

Understanding Clustrolin Technology

Clustrolin applies DBSCAN (Density-Based Spatial Clustering of Applications with Noise) algorithms to creative applications. This advanced technology is typically used in fraud detection, data analysis, and scientific research. Smart Banner Hub is the first platform to harness this mathematical power for personal creativity.

Here is how Clustrolin creates each template animation:

  1. 2D point cloud generation — Mathematical coordinates are distributed across the video canvas.
  2. DBSCAN clustering analysis — The algorithm identifies dense regions and groups related points together.
  3. Color assignment per cluster — Each discovered cluster receives unique colors and animation properties.
  4. Animation sequencing — Clusters animate in evolving patterns throughout the video.
  5. Template-ready output — The pre-generated mathematical art is packaged and ready for your personalization.
