GifGun 2 is the second generation of Nik Ska's GIF creation tool for After Effects, built around one-click animated GIF output. Beyond GIFs, it now handles WEBP and MP4 formats, and ships with standalone and web apps in addition to the After Effects integration.
The plugin includes Alpha Matte for GIF, which mattes semi-transparent pixels around the alpha edge, along with a GIF size optimization algorithm and savable presets. WEBP rendering supports looping and a Sharp YUV mode, while MP4 export uses 2-pass rendering. Recent updates have focused on stability, UI changes, alpha handling, and color palette generation for transparent GIFs.
GifGun 2 runs with After Effects 2020 through 2026 and sits at rank 56 in the aescripts library. A demo video is available, and it's listed here as free.
