Convert videos to high-quality GIFs

Source on GitHub

Gifski is a macOS app for the gifski encoder, which converts videos to GIF animations using pngquant's fancy features for efficient cross-frame palettes and temporal dithering. It produces animated GIFs that use thousands of colors per frame.

If you don't have a video, you can try the app out with this one.
