How is made. 🛠

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

• AI -> torch / onnxruntime-directml
• GUI -> customtkinter
• Image/video -> OpenCV / moviepy
• Packaging -> nuitka

Requirements. 🤓

• Windows 11 / Windows 10
• RAM >= 8Gb
• Any Directx12 compatible GPU with >= 4GB VRAM

Features.

• Elegant and easy to use GUI
• Image and Video upscale
• Multiple GPUs support
• Compatible images - jpg, png, tif, bmp, webp, heic
• Compatible video - mp4, wemb, mkv, flv, gif, avi, mov, mpg, qt, 3gp
• Automatic image tilling to avoid gpu VRAM limitation
• Resize image/video before upscaling
• Interpolation beetween original file and upscaled file
• Video upscaling STOP&RESUME
• PRIVACY FOCUSED - no internet connection required / everything is on your PC

Next steps. 🤫

• 1.X versions
  • 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)
• 2.X versions
  • New, completely redesigned graphical interface based on @customtkinter
  • Upscaling images and videos at once (currently it is possible to upscale images or single video)
  • Upscale multiple videos at once
  • Choose upscaled video extension
  • Interpolation between the original and upscaled image/video
  • More Interpolation levels (Low, Medium, High)
  • Show the remaining time to complete video upscaling
  • Support for SRVGGNetCompact AI architecture
  • Metadata extraction and application from original file to upscaled file (via exiftool)
• 3.X versions
  • New AI engine powered by onnxruntime-directml (https://github.com/microsoft/onnxruntime))
  • Python 3.11 (performance improvements)
  • Python 3.12 (performance improvements)
  • Display images/videos upscaled resolution in the GUI
  • Updated FFMPEG to version 7.x (latest release)
  • Saving user settings (AI model, GPU, CPU etc.)
  • Video multi-threading AI upscale
  • Video upscaling STOP&RESUME
