video2x

• Added support for RealCUGAN ncnn Vulkan
• Added pause function
  • Use the global hotkey Ctrl+Alt+V or send SIGUSR1 to the main process to pause
• Fixed various problems with the progress bar

The container has also been patched so it will run fine on both AMD and NVIDIA GPUs. The required Docker arguments have changed for AMD GPUs. See the Wiki page for more information.

• Enabled audio, subtitle, data, and attachment streams copying support
• Fixed a bug in argument parsing

• Changed the use of term "driver" to "algorithm" since the backend implementation is now mostly abstracted from the user.
  • The argument -d, --driver has been renamed to -a, --algorithm.

• Fixed two memory usage issues in beta 1. It shouldn't blow your memory up in 30 seconds now.

⚠️ Known Issues

• Errors in handling queued images results in abnormal memory consumption. The program will fill your RAM in a short time if you attempt to process a large video file. This issue has been fixed in 5.0.0-beta2.

Bug Fixes

• Fixed Anime4KCPP driver import error
• Rolled Gifski back to a version without output bugs

⚠️ Known Issues

• Warning: Some users have reported that the software did not make it clear that the cache folder will be deleted after the upscale is completed. If you want to use a custom cache folder, make sure to use a designated folder with no other contents in it as the cache folder will be wiped after upscaling is done. A warning will be added into the GUI in the upcoming version.

New Features

• Updated waifu2x-ncnn-vulkan arguments

New Features

• Arbitrary scaling ratio support for all drivers
• Arbitrary scaling resolution (width/height) support for all drivers
  • Allows only one of width/height to be specified and the other side will be calculated automatically according to the scaling ratio
• Removed the use of shlex.join and := to make the program compatible with Python 3.6 and higher
• Updated UI design for better visibility of the preview image
• Redesigned logging system and error reporting system
  • Logs can now be saved optionally when the program runs into an error
  • If unspecified, logs will be deleted automatically upon normal exit of the program
  • Logs are now written to a tempfile.TemporaryFile object by default instead of a conventional log file
• Various other improvements and code optimizations

Bug Fixes

• Fixed waifu2x-caffe output quality option
• Fixed Gifski output resolution issues

Other Notes

• waifu2x-caffe has recently upgraded their CUDA Toolkit (11.0) and cuDNN (8.0.3) versions. This makes it incompatible with some of NVIDIA's older models of GPUs
  • To run the newest waifu2x-caffe (version 1.2.0.4 at the time of writing this note), your GPU must have a Compute Capability >= 3.5
  • Check this link for a list of NVIDIA's GPUs and their Compute Capabilities
