    开源了一个光流插帧算法 RIFE，Github 项目，arXiv 论文

    比现有的光流插帧方法加速 5x ~ 20x 目前在优化效果和写视频处理脚本，欢迎关注

    720p 2x 插帧 30+FPS (TITAN X (Pascal)

    也可用于生成慢动作 gif

    支持 CPU，我的 mac 上生成 256x448 大小的 16x gif 需要 15 秒

    目前提供脚本可以从两张输入图，插出 2^K 个中间帧，如下： demo

    现在可以在线用 colab 插帧了，欢迎体验

    网络不复杂，结果还挺好的，示例图片只有胳膊区域有可见失真，旷视就是旷视。
    不了解这个方向，感觉唯一的遗憾是只能单次插出中间帧，倍数可控性高的同时复杂度也高。
