Parameters ---------- new_duration : float Duration for the new transformed clip. If None, will be that of the current clip. abruptness : float Slope shape in the acceleration-deceleration function. It will depend on the value of the parameter: * ``-1 < abruptness < 0``: speed up, down, up. * ``abruptness == 0``: no effect. * ``abruptness > 0``: speed down, up, down. soonness : float For positive abruptness, determines how soon the transformation occurs. Should be a positive number. Raises ------ ValueError When ``sooness`` argument is lower than 0. Examples -------- The following graphs show functions generated by different combinations of arguments, where the value of the slopes represents the speed of the videos generated, being the linear function (in red) a combination that does not produce any transformation. .. image:: /_static/medias/accel_decel-fx-params.png :alt: acced_decel FX parameters combinations N new_duration? abruptnesssoonnessc@d|zfd}||||z |zzS)Nrcdfdfd}|dk|z|dk||zzS)Nc ddz z|zzS)N?)tas LC:\Projects\Historical\venv\Lib\site-packages\moviepy/video/fx/AccelDecel.pyf1z1AccelDecel._f_accel_decel.._f..f19sQ'1a400c&dd|z z S)Nrr)rrs rf2z1AccelDecel._f_accel_decel.._f..f2<s22a!e99}$rrr)rrrrs @r_fz%AccelDecel._f_accel_decel.._f8se 1 1 1 1 1 % % % % %Grr!uu$SBBqEE'99 9rr)selfr old_durationrr r rrs @r_f_accel_decelzAccelDecel._f_accel_decel3sI *  : : : : :bb!l"2x!?@@@@rcj j_jdkrtdfdjS)zApply the effect to the clip.Nrz%'sooness' should be a positive numberc`|jjjjS)N)rrrr r )rdurationrr r )rcliprs rz"AccelDecel.apply..Ls4d))!]!.? *r)rrr ValueErrortime_transform with_duration)rrs``rapplyzAccelDecel.applyCsv   $ $ D  =1  DEE E""        -) * * +r)rr) __name__ __module__ __qualname____doc__rfloat__annotations__r r rr$rrrrrs%%NL%JHeGJAAAA +++++rrN) dataclassesrmoviepy.Effectrrrrrr-ss!!!!!!!!!!!!
