For and only for modern macOS.
IINA is born to be a modern macOS application, from its framework to user interface. It adopts the post-Yosemite design language and keeps up the pace of new technologies like Force Touch, Touch Bar and Picture-in-Picture.
Revolutionary user experience.
IINA simplified a lot of user interactions. In addition of traditional cascaded menus, it prefers using interactive UI components and gestures to give you intuitive, flexible and powerful control of the playback.
Based on mpv, one of the most powerful media player projects ever, IINA supports almost all common media types (even GIF) and stably output high-quality video that optimized for retina screen. MPV's config file and script system are also integrated.
You are the target user.
IINA is made by a user like you, who (may be) also having been expected for a powerful and elegant media player on macOS for years. Whether you just got your first Mac or are already a professional mpv user, IINA will satisfy you for its customizability and expandability.
Still in active development.
IINA is written in pure Swift and open source. It's currently a personal project, but please feel free to contribute it by raising issues, sending feature requests or bug reports on github or by email. Of course, it's free and will be free forever.
