RealScaler - fast image/video AI upscaler app (Real-ESRGAN)

RealScaler is a Windows app that uses Real-ESRGAN artificial intelligence to enhance, enlarge and reduce noise in photographs and videos.

RealScaler is completely written in Python, from backend to frontend. External packages are:

• AI -> torch / torch-directml
• GUI -> tkinter / tkdnd / sv_ttk
• Image/video -> openCV / moviepy
• Packaging -> pyinstaller
• Miscellaneous -> pywin32 / win32mica

• Windows 11 / Windows 10
• RAM >= 8Gb
• Directx12 compatible GPU:
  • any AMD >= Radeon HD 7000 series
  • any Intel HD Integrated >= 4th-gen core
  • any NVIDIA >= GTX 600 series

• Easy to use GUI
• Image/list of images upscale
• Video upscale
• Drag&drop files [image/multiple images/video]
• Automatic image tiling and merging to avoid gpu VRAM limitation
• Resize image/video before upscaling
• Multiple gpu backend
• Compatible images - png, jpeg, bmp, webp, tif
• Compatible video - mp4, wemb, gif, mkv, flv, avi, mov, qt

• Update 2.0 (now under development)
  • Python 3.11 (expecting ~30% more performance)
  • torch/torch-directml 2.0 (more performance)
  • a new completely redesigned graphical interface, with many more options for the user
  • upscaling of images and videos at once (currently it is possible to upscale a single image, a list of images or a single video)
  • upscale multiple videos at once
• Switch to Pytorch-directml to support all Directx12 compatible gpu (AMD, Intel, Nvidia)
• New GUI with Windows 11 style
• Include audio for upscaled video
• Optimizing video frame resize and extraction speed
• Multi GPU support (for pc with double GPU, integrated + dedicated)
• Python 3.10 (expecting ~10% more performance)

• Windows10 - the app starts with white colored navbar instead of dark
• Upscaling multiple images doesn't free GPU Vram, so the it is very likely that the process will fail when the gpu memory fills up
• Filenames with non-latin symbols (for example kangy, cyrillic etc.) not supported - [Temp solution] rename files like "image" or "video"
• When running RealScaler as Administrator, drag&drop is not working

• Original

• RealESRGANx4 - upscaled in 3 minutes and 23 seconds

• RealESR_Gx4 - upscaled in 57 seconds
