It's only enabled if you compile it with -features=video: gifski -o out.gif video.mp4 LicenseĪGPL 3 or later. Note that pre-built binaries distributed from the website don't support video. The tool optionally supports decoding video directly. If the input was ever encoded using a lossy video codec it's recommended to at least halve size of the frames to hide compression artefacts and counter chroma subsampling that was done by the video codec. You can also resize frames (with -W option). You can use ffmpeg command to convert any video to PNG frames: ffmpeg -i video.webm frame % 04d.pngĪnd then make the GIF from the frames: gifski -o anim.gif frame *.png If you have Homebrew, you can also get it with brew install gifski. Run cargo build -release -features=openmp to build from source. If you have Rust, you can also get it with cargo install gifski. It's a CLI tool, but it can also be compiled as a library for seamelss use in other apps. It produces animated GIFs that use thousands of colors per frame. Gifski converts video frames to GIF animations using pngquant's fancy features for efficient cross-frame palettes and temporal dithering.
