- # install avisynth, extract megui somewhere then extract defish.dll too
- #
- # also you need a script called defish.avs,
- # it's included below just copypaste this into notepad:
- LoadPlugin("C:\Users\ed\bin\megui\tools\lsmash\LSMASHSource.dll")
- LSMASHVideoSource("C0008.MP4").convertToRgb32()
- LoadPlugin("C:\Users\ed\bin\avisynth\defish.dll")
- defish(fov=84)
- convertToYV12()
- ####### END OF DEFISH.AVS #######
- # remember to change the paths to the dll files above actually
- # just deshake
