Futuristic HUD Square Scanning Frame with Red Glow Animation

This animated overlay features a minimalist white square frame with corner brackets, evoking a high-tech head-up display or scanning interface. A horizontal scan line moves smoothly up and down across the frame, leaving a soft red gradient glow in its wake. The rhythmic motion suggests data processing, biometric scanning, or system analysis. Its clean vector-style lines and modern aesthetic make it an ideal tool for tech-focused projects, security-themed content, or futuristic user interface mockups. The animation includes a transparent background, allowing editors to easily layer it over footage to simulate facial recognition or digital target tracking. The vibrant red accent adds a sense of urgency or active monitoring, while the simple geometric shapes ensure it remains legible and professional in various broadcast and digital contexts.
