RealESRGAN GUI Wrapper

A dedicated Python GUI for Real-ESRGAN designed specifically for video upscaling stability.

Unlike other GUIs that might cause audio desync or variable framerate issues, this tool uses a "Strict Sync" method: it deconstructs video into frames, upscales them, and rebuilds the video using the exact source framerate and audio stream.

Features

• Strict Sync Mode: Forces constant frame rate (CFR) to prevent audio desync.
• Progress Tracking: Real-time log output and progress bar.
• Image & Video Support: Upscale single images or full videos.
• Model Selection: Support for realesr-animevideov3, realesrgan-x4plus, and more.
• Hardware Agnostic: Works with whatever RealESRGAN binary you provide (NCNN/Vulkan supported).
