IT (clip, int "fps", int "threshold", int "pthreshold", string "ref", bool "blend", bool "debug", string "read", string "write", string "log", int "dimode"

clip   =

Input clip.

int  fps = 24

Set to true to show debug information.

string  read = NULL

string  write = NULL

string  log = NULL

int  dimode = 1

Deinterlace mode:

• 0 : none
• 1 : deinterlace
• 2 : simple blur
• 3 : one field
• 4 : end
• 5 : deinterlace b
