FLIF only has a lossless mode. For lossless animation, it usually beats GIF, APNG, MNG, WebP and BPG. It is the only responsive animation format afaik.<p>For lossy movies, actual video codecs are best, since they&#x27;re designed for that. BPG is essentially HEVC (a great but patent-encumbered video codec) so it should be good at lossy movies -- it will be worse on line-art animations with hard edges like e.g. cartoons, or animations with transparency.
