Videfy.ai is an AI-powered video creation platform enabling creators and teams to generate and refine video content directly in the browser. As the product evolves toward hybrid AI + manual editing workflows, professional-grade timeline interactions became critical for user trust and editing precision.
Designed and implemented a high-performance timeline zoom infrastructure for Videfy.ai’s web-based video editor. The system eliminates the common 'jumping playhead' issue by anchoring zoom operations to the playhead during precision interactions, while preserving stability through uniform scaling for high-frequency wheel events. UX behavior was benchmarked against industry leaders such as CapCut and Canva to ensure professional editing standards.
Resolved unstable timeline zoom behavior that caused playhead desynchronization, delivering a professional, desktop-grade editing experience in the browser.
Implemented a custom anchoring algorithm based on time-to-pixel ratios calculated before and after scaling. Scroll adjustments are applied within the same animation frame as layout reflow to eliminate flicker. Zoom logic is intentionally split between wheel-based free scaling and slider-based anchored precision, aligning with professional video editor UX standards.
Improved editor usability and perceived quality, enabling Videfy.ai to support advanced editing workflows and positioning the product closer to professional desktop-grade video tools.
