  • Added metadata copy from original file to upscaled file via exiftool

• GUI

  • Completely revised GUI, now cleaner and more elegant
  • Added new widgets for info button and in case of error
  • Updated info texts and widget texts

• BUGFIX/IMPROVEMENTS

VirusTotal RS 2.7 https://www.virustotal.com/gui/file/be966d0f96a5e22f3e135e9af4de4a80e55f17cc1a0ea65821ea9512516b553c?nocache=1

• GUI

  • The app will now report the remaining time to complete video upscaling
  • The app now reports the progress in % instead of the number of frames
  • Updated info texts

• BUGFIXES / IMPROVEMENTS

  • Drastically reduced CPU utilization by 90% without impacting upscale speed
  • Updated dependencies
  • General code cleaning and improvements

NEW

• Completely rewrote the frame resizing algorithm

  • there is no more frame resizing phase, rather frames are resized during AI operations
  • this change allows to save time and disk space

• Added a new feature of interpolating the AI-generated image/frame and original image/frame

  • in many cases it allows to increase the "naturalness" of the final image/video
  • it allows to solve graphical problems due to tiles when using tiles/merge function
  • the file created with Interpolation will be saved with "_interpolated" in filename
  • added a widget to choose whether or not to enable this feature (by default it is enabled)

GUI

• The app will now report the index of the file that is being processed
• Removed itch.io button
• Updated some texts

BUGFIX & IMPROVEMENTS

• By default Image output is set to ".jpg"
• Removed unused dependencies
• Updated dependencies
• General code cleaning and improvements

NEW

• Completely rewrote the tile management algorithm:

  • cutting an image into tiles is ~60% faster
  • tiles now also support transparent images
  • tiles are no longer saved as files, to save disk space and time
  • now the image/frame upscaled as a result of tiles is interpolated with the original image/frame: this reduces graphical defects while maintaining upscale quality

• Added "Video output" widget that allows you to choose the extension of the upscaled video:

  • .mp4, produces well compressed and good quality video
  • .avi, produces very high quality video without compression
  • .webm, produces very compressed and very light video with no audio

GUI

• The app will now tell how many tiles the images are divided into during upscaling
• Removed Mica effect (transparency) due to incompatibilities: often did not allow to select, zoom, and move the application window

BUGFIX & IMPROVEMENTS

• By default AI precision is set to "Half precision"
• By default now "Input resolution %" is set to 50%
• Partially rewrote and cleaned up more than 50% of the code
• Updated all dependencies
