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)NrcTfdfd}|dk|z|dk\||zzS)Nc ddz z|zzS)N?)tas Y/root/workspace/ytshorts/venv/lib/python3.12/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<s2a!e9}$rrr)rrrrs @r_fz%AccelDecel._f_accel_decel.._f8s4 1 %Gr!u$SBqE'99 9rr)selfr old_durationrr r rrs @r_f_accel_decelzAccelDecel._f_accel_decel3s0 *  :b!l"2x!?@@@rcjj_jdkr tdj fdj jS)zApply the effect to the clip.rz%'sooness' should be a positive numbercj|jjjjS)N)rrrr r )rdurationrr r )rcliprs rz"AccelDecel.apply..Ls8d))!]]!..?? *r)rrr ValueErrortime_transform with_duration)rrs``rapplyzAccelDecel.applyCs]    $ $ D  ==1 DE E""   -)) * +r)rr) __name__ __module__ __qualname____doc__rfloat__annotations__r r rr$rrrrrs:%NL%JHeGJA +rrN) dataclassesrmoviepy.Effectrrrrrr-s)!!
