Continuous Hardware-Accelerated Custom Outro Playback: Rebuilt custom outro video playback with native GPU continuous decoding, eliminating seek-thrashing, playback stutter, and decoder contention between stage monitor and timeline.
Outro Stage Overlay Guard & Headline Suppression: Fully decoupled stage text overlays from outro sequences: headlines, subtitles, and watermarks are automatically suppressed during outro playback and scrubbing, keeping avatar, logo, and custom video cards completely clean and unobstructed.
Timeline Lock Audio Synchronization & Riser Continuity: Resolved URL encoding mismatches in the background audio engine, enabling instant, one-load playback for all background music tracks, energy surges, and risers upon locking the timeline.
Active Word Karaoke Subtitle Highlighting: Corrected ASS subtitle tag formatting for sub-frame karaoke animations and added intelligent dynamic color contrast (vibrant #FFE600 highlight on white base text) for both static and word-by-word modes.

Dynamic Background Blur & Canvas Framing: Added live video background blur with dedicated stage canvas (centered-stage-blur-canvas), real-time blur radius sliders (5px to 50px) with instant presets (Subtle 10px, Medium 20px, Heavy 35px), background image blur, direct stage video drag positioning, decoupled padding, and 1:1 hardware FFmpeg boxblur export parity.
Streamlined Flat Inspector Accordions: Redesigned inspector property panels with minimal flat accordions, elevated header hierarchy, uniform subtle dividers (#e5e5e5), isolated sidebar tabs, and complete elimination of border preview flashes during scrubbing.
Watermark Resizing & Brand Typography: Resized social media icons (Instagram, YouTube, TikTok, X) to match text height with zero vertical wobble, upgraded high-resolution Instagram vector, and added secondary watermark handle support with independent font, color, and coordinate controls.
Export Duration Precision & 60 FPS GPU Rendering: Upgraded container stream probing in media_probe to microsecond precision, eliminating clipped video tails or trailing black frames, backed by standard 60 FPS NVENC and AMF hardware encoding.
Advanced Headline & Subtitle Text Effects: Integrated real-time drop shadow blur radius sliders (0px to 50px), custom stroke outlines with synchronized color pickers, and sub-frame karaoke timing highlight precision.
Unified Modal Theming & Color Pickers: Harmonized modal elevation, dark/light theme overrides across all dialogs, and synchronized hex, RGB/HSL, alpha opacity, and swatch history across text, background, watermark, and template styling.
Anti-Tamper Beta Lifecycle Engine: Integrated automated 30-day testing cycle monitoring with anti-tamper clock verification and graceful preview deprecation prompts, backed by a strict permanent data safety guarantee for all .yizerge project files and exports.
Hardened Production UI Bundling & Obfuscation: Upgraded release packaging with bundle_production_ui to compress, minify, and obfuscate all 37 modular JavaScript files into a single hardened payload, excluding raw source trees from distributions.
