CineCanvas Ship of Agony LABs توسط

Get the most out of your 21:9 ultrawide display on YouTube. CineCanvas delivers smart aspect ratio scaling, soft edge blending, live ambient glow, customizable side frames, and custom wallpapers — engineered exclusively for YouTube.

• Optimized for YouTube: CineCanvas is specifically designed and optimized for a flawless ultrawide viewing experience on YouTube.
• Universal YouTube Integration: Seamlessly works with standard YouTube desktop playback, theater mode, and full-screen view.
• Direct In-Player Control: Access all mode selections, toggles, and adjustment sliders straight from the embedded player button without needing to open the browser menu.
• Feature Requests & Feedback: If you have requests for additional features or enhancements, please reach out via email to ship.of.agony.labs@gmail.com.

• 21:9 Crop: Zooms seamlessly to completely fill your 21:9 ultrawide monitor without distorting the picture.
• 21:9 Stretch: Expands 16:9 videos horizontally to cover the entire panel.
• Original (Off): Keeps native aspect ratios untouched.

• Vivid Ambilight: Maximum luminance and rich, saturated dynamic glow for full ultrawide immersion.
• Soft Ambient Glow: Milky, diffused background projection reflecting live colors across the side wings.
• Cinematic Shadow: Subtle edge darkening paired with smooth ambient falloff.
• Granular Background Blur Slider: Dedicated slider (0px to 80px) accessible directly in the player and popup, ranging from mirror-sharp reflections to deeply blurred velvety auras.

• GPU-Powered CSS Masking: Utilizes native linear gradient masks directly on the <video> element, avoiding expensive filter bottlenecks.
• Seamless Inward Fade Slider: Dedicated control (0 to 50) to soften harsh video borders. At 0, edges stay razor-sharp; higher values blend the video naturally into the ambient aura or background.
• Automatic Pillarbox Boundary Correction: Automatically detects hardcoded black bars in 4:3 streams and positions the soft blend precisely where visible video begins.

• Seamless Bezel Transition: Smooth slider (0% to 100%) fading outer monitor edges into deep black for a clean transition into physical screen bezels.

• Intelligent Bar Detection: Scans for black letterbox and pillarbox bars (including hardcoded 4:3 content inside 16:9 containers) and adapts video scaling dynamically.

• Full 0% to 100% Dimming Slider: Adjust background brightness all the way down to true solid black.
• Cinema Side Wings (Frames): Replace plain black pillarbox bars with stylized official YouTube badges, pre-saved theater frames (Frame 1 to Frame 5), or upload your own custom high-resolution wallpaper.
• Independent Presets & Profiles: Slider values for static frames and dynamic Ambilight operate independently — fine-tuning one does not overwrite the other.
• Dynamic Theme Switching: Supports automatic or manual Dark/Light mode switching.

• Automatic Language Detection: CineCanvas detects and matches your browser language automatically.
• 10 Fully Localized Languages: Both the browser popup and the embedded in-player menu are localized in English, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Czech, and Russian (English serves as the default fallback).

• Alt + C: Cycle through video and ambilight modes.
• Alt + W: Toggle side wing overlays.
• Alt + L: Switch wing themes (Dark / Light).
• Alt + A: Enable or disable automatic letterbox detection.
• On-Screen Display (OSD): Subtle HUD badges provide immediate visual feedback on keypresses.

• Completely Free: No paywalls, no subscriptions, no ads.
• Zero Data Collection: No analytics, no telemetry, no external server requests (data_collection_permissions: none).
• 100% Local Processing: Color extraction, canvas rendering, and custom background storage operate strictly client-side within your browser.
