Usage

SickJumps(clip c, int "first_frame", int "last_frame",
          float "start_multiplier", float "full_multiplier",
          float "up_seconds", float "down_seconds",
          string "script_variable", float "end_multiplier")

c clip

• The input clip. Can be any colorspace and audio format.

first_frame int, default 0

• The first frame of the ramp up to full speed.

last_frame int, default c frame count - 1

• The last frame of the ramp down to the ending speed.

start_multiplier float, default 1.0

• The speed multiplier to use before the ramp up.

full_multiplier float, default 2.0

• The speed multiplier to use between ramp up and ramp down.

up_seconds float, default c length / 4.0
down_seconds float, default c length / 4.0

• The resulting duration, in seconds, of the ramp up and ramp down.

script_variable string

• Assigns a string, containing some debug info, to the specified variable
  name. Said string is colon-delimited, and takes the following form:

  "frame:X:multiplier:Y:section:Z"

  Respectively, it provides the current input frame number, multiplier, and
  a simple label describing what section ("before", "ramp up", "full speed",
  "ramp down", or "after") the current output frame resides in.

  The string is updated each frame, and is intended for use with Avisynth's
  runtime environment. Be sure to set ScriptClip's after_frame to true so
  the variable gets set properly.

  See the source distribution for an example script that demonstrates one
  approach to parsing the string and using some of its information.

end_multiplier float, default start_multiplier

• The speed multiplier to use after the ramp down.
