Installation.

QualityScaler is completely portable; just download, unzip and execute the file .exe

Supported AI Backend.

• Nvidia Cuda [v10.2]
• CPU [works without GPU, but is very slow]

Features.

• Easy to use GUI
• Images and video upscale
• Drag&drop files [image/multiple images/video]
• Different upscale factors:
  • auto - automatic choose best upscale factor for the GPU used (to avoid running out of VRAM)
  • x1 - mantain same resolution but reconstruct & enhance the image (ideal for bigger images)
  • x2 - upscale factor 2: 500x500px -> 1000x1000px
  • x4 - upscale factor 4: 500x500px -> 2000x2000px
• Cpu and Gpu [cuda] backend
• Compatible images - PNG, JPEG, BMP, WEBP, TIF
• Compatible video - MP4, WEBM, GIF, MKV, FLV, AVI, MOV

Next steps.

• Use both model for the upscale
• Include audio for upscaled video
• Support for other GPUs (AMD, Intel) with new backend
