##中等消耗。偏保守型补帧策略，片源类型的适用性较广

import vapoursynth as vs
core = vs.core
clip = video_in
vfps = int(container_fps*1e8)
dfps = 60000

##dfps = 设置为你的目标帧率，例 60000 即60fps。特殊值例如 display_fps/2*1000 即目标为显示器刷新率的一半帧率，值填 container_fps*2*1000 即倍帧
##更高的帧率更加耗能，产生更多伪影，通常是不必要的。例如对于144hz的显示器来说，最多只需要补到72fps，剩下的让mpv.conf中的 --interpolation 平滑过渡到144fps
