Video Enhancer by Chandra Kant

Transform washed-out streaming video and recover crushed shadow details on LED and IPS displays in real time. Video Enhancer delivers simulated HDR color grading, contrast calibration, and edge refinement directly to HTML5 video players across the web without modifying the source stream or causing frame drops.

KEY FEATURES

• On-Screen Quick Tweak HUD: Adjust settings directly over the video player without opening the extension popup. The sleek on-screen bar auto-hides smoothly after idle time and wakes up instantly on mouse movement.
• Proportional Drag & Drop: Drag the HUD or tweak panel anywhere on screen. It remembers its exact relative placement across window resizing, theater mode, and fullscreen playback. Double-click the header or bar to quickly reset to default.
• Quick Dismissal: Press Escape to close the adjustment panel without exiting browser fullscreen, or click anywhere on the video backdrop.
• Shadow Boost: Recovers lost details in pitch-black and dark night scenes using a calibrated non-linear gamma curve that preserves true black anchors without washing out contrast or turning blacks milky.
• Filmic Highlight Rolloff: Calibrated anti-clipping knee curve (18% knee, 40% compression) that rolls off harsh highlights to prevent blown-out whites.
• Anti-Blooming Sharpness Mask: Custom SVG convolution matrix sharpening paired with a 33-point luminance protection curve. High-luminance areas (such as white clothing and bright lights) automatically roll off to eliminate unnatural halos and edge blooming.
• Decoupled Saturation & Skin-Safe Vibrance: Independent chrominance controls allowing you to boost colors while protecting natural skin tones and neutral whites.
• Calibrated Dynamic Range: Contrast is tuned with strict bounds (75% to 135%) to protect dynamic range and prevent highlight bleaching.
• Direct 1:1 Control Pipeline: All 9 visual sliders operate independently with true 1:1 direct fidelity, free of compounding multiplier controls.
• Audio Booster & Dialogue Compressor: Boost quiet audio up to 400% with dynamic dialogue leveling for clearer speech during loud action scenes.
• Aspect Ratio & Ultrawide Zoom: Easily fit 16:9 video to 21:9 ultrawide displays (no black bars), stretch, fill, or mirror horizontally.
• Per-Site Memory: Automatically remembers custom settings and enabled states per website.
• Image & Thumbnail Support: Optional toggle to apply your color tuning to static images and thumbnails across the web.
