About YouTube Fullscreen: Anamorphic Scaler

🚀 YOUTUBE FULLSCREEN: 𝗔𝗻𝗮𝗺𝗼𝗿𝗽𝗵𝗶𝗰 𝗦𝗰𝗮𝗹𝗲𝗿 Tired of choosing between black bars on the sides of widescreen videos (pillarboxing) or cropping away the top and bottom of the image? Most zoom extensions use simple linear stretching that makes people look fat and distorted, or they crop the image, losing crucial content. YouTube Fullscreen: Anamorphic Scaler is different. It performs non-linear anamorphic scaling, keeping the center of the video completely natural while smoothly stretching the sides to fill your screen. ✨ 【 WHY USERS LOVE IT 】 ✅ SINE-BASED SCALING (MODE A): Dynamically stretches only the outer edges of the video while keeping the center 100% natural and distortion-free. ✅ HYBRID ZOOM (MODE B): Combines sine stretch with a customizable zoom factor (0% to 20%) to fill ultra-widescreen displays without excessive stretching or cropping. ✅ AUTOMATIC CROP DETECTOR: Automatically detects and crops hardcoded black bars (letterbox/pillarbox) inside video streams, scaling only the actual video content. ✅ GPU POWERED: Directly uses the rendering pipeline on your graphics card. Zero CPU overhead, zero lag, and fluid 60fps playback. ✅ INTEGRATED BUTTON: Adds a native-looking "NLS" toggle button directly inside YouTube's player controls, next to the cinema mode button. ✅ SPA COMPATIBLE: Works seamlessly with YouTube's single-page app architecture, keeping your settings active across page transitions. ▬▬▬ 🛠 𝗛𝗢𝗪 𝗧𝗢 𝗨𝗦E ▬▬▬ 1️⃣ Open any video on YouTube. 2️⃣ Click the "NLS" button in the video player toolbar or open the extension popup. 3️⃣ Toggle between Mode A (Sine) and Mode B (Hybrid), and adjust the zoom slider to customize your viewing experience. ▬▬▬ 💎 𝗣𝗥𝗜𝗖𝗜𝗡𝗚 & 𝗣𝗥𝗢 ▬▬▬ 🔹 FREE: Scale up to 10 unique YouTube videos per day. 🔹 PRO: One-time payment unlocks unlimited video scaling for a lifetime. 🛡️ 【 PRIVACY & LEGAL 】 As a German developer, I prioritize your privacy and consumer rights. ❌ NO data tracking. ❌ NO external servers. ✅ SECURE payment via Stripe/ExtensionPay. ✅ LOCAL storage of settings only. About: Developed by Dieter Käppel. We build software that solves real-world problems with efficiency and precision.
