Open Source Swift Video Encoders

This 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 and up to 50 FPS (useful for showing off design work on Dribbble). You can also produce smaller lower quality GIFs when needed with the “Quality” slider, thanks to gifsicle. Gifski supports all the video formats that macOS supports (.mp4 or .mov with H264, HEVC, ProRes, etc). The QuickTime Animation format is not supported. Use ProRes 4444 XQ instead. It's more efficient, more widely supported, and like QuickTime Animation, it also supports alpha channel. Gifski has a bunch of settings like changing dimensions, speed, frame rate, quality, looping, and more.
