Chroma Key Editor

Chroma Key Editor is a browser-based tool that removes a green screen from video and composites a selected background. It supports multiple chroma colors, adjustable tolerance, spill suppression, and edge feathering for cleaner edges. The processing concept hinges on sampling the chroma color, evaluating per-pixel color difference in a suitable color space, and masking non-keyed pixels. The tool then overlays the keyed foreground onto the chosen background and encodes the result to common formats. Real-time preview helps you iterate on lighting, spacing, and background choice. This tool benefits creators, educators, marketers, and event producers who need quick, editable green-screen videos without heavy software. Unique value lies in browser-based performance, playback accuracy, and flexible background options, including uploads or library assets. Core features include color sampling, configurable tolerance, spill suppression, edge feathering, background replacement, input/output format options, and GPU-accelerated rendering where available. Typical use cases include product demos, tutorials, classroom videos, and social media clips that demand rapid turnaround and consistent visuals.
