Video editing is a critical skill in the modern digital landscape, required by content creators, educators, journalists, and professionals across industries. Traditional video editing tools demand significant technical expertise, prolonged learning curves, and complex timeline-based interfaces that discourage casual adoption. This paper presents Praxys Studio, an intelligent browser-based video editing platform that leverages Artificial Intelligence and Natural Language Processing (NLP) to allow users to edit videos through plain English descriptions. Instead of manually trimming clips, adjusting color grades, or configuring export settings, users simply type commands such as "trim to the best 30 seconds" or "make it cinematic," and the system interprets these instructions and applies the corresponding FFmpeg video-processing operations in real time. The system processes all video data locally in the browser using FFmpeg compiled to WebAssembly, ensuring complete user privacy with zero cloud uploads. Experimental evaluation demonstrates high intent-to-operation translation accuracy, sub-second processing latency for most operations, and strong user satisfaction scores across diverse editing tasks. Praxys Studio represents a significant step toward democratizing video production by combining AI language understanding with professional-grade video processing capabilities.
