A professional-grade, hardware-accelerated video optimization suite. This version introduces the major Python Pro GUI, offering a significant leap in stability, visual fidelity, and advanced quality-targeting over the legacy PowerShell scripts.
This release marks the transition to Python as the primary interface, while retaining the core high-performance FFmpeg logic that made the PowerShell version a success.
- Professional Desktop Interface: Built with
CustomTkinterfor a sleek, system-aware Light/Dark mode experience. - VMAF Target Ladder (Multi-Pass): Automatically hunt for the perfect visual quality. Input targets like
95, 93, 91and the engine will iterate until the optimal size-to-quality ratio is found. - Persistent Config System: All settings (Encoders, Presets, Quality, Paths) are now saved automatically to
.Video Optimizer/config.json. - Smart Encoder Intelligence: Auto-detects all supported hardware encoders (NVIDIA NVENC, AMD AMF, Intel QSV) and marks unsupported ones.
- Beautified Real-Time Logs: High-fidelity console output with professional status prefixes and detailed process feedback.
- Robust Cache & Resume: Integrated signature-based caching to prevent redundant processing of already optimized files.
- Full Hardware Parity: Matches the original PowerShell script's hardware detection and logic.
- GPU-Accelerated Decoding: Uses
-hwaccelflags to ensure the GPU handles both decoding AND encoding for maximum throughput. - NVENC Visual Tuning: Automatically injects
-spatial_aqand-aq-strengthfor superior NVIDIA encoding quality. - Audio Compatibility Fallback: Intelligent stream analysis automatically falls back to high-quality AAC if source audio is incompatible with the target container.
- Windows 10/11
- FFmpeg (Must be in your system
PATH)- Download FFmpeg here
- Crucial: Build must include
libvmaffor advanced quality targeting.
- Python 3.10+ (The launcher handles virtual environment setup automatically)
- Launch: Double-click
Video Optimizer.bat. - Select: Choose your source directory.
- Optimize: Configure your quality targets (or use the recommended VMAF 93) and click START PRO OPTIMIZATION.
The original PowerShell engine remains available for CLI-focused workflows. It can be run directly or via the web:
