In this article we will see how we can change time line of the video file clip in MoviePy. MoviePy is a Python module for video editing, which can be used for basic operations on videos and GIF’s. In video editing, timeline is a commonly used interface found in most video editing programs. This interface enables authors to lay a video project out in a linear fashion horizontally across a monitor. A chronological display of an edited sequence in a non-linear editing system. By changing timeline of the video we can change the sequence of events in the video.
In order to do this we will use fl_time method with the VideoFileClip object Syntax : clip.fl_time(method) Argument : It takes time method as argument Return : It returns VideoFileClip object
Below is the implementation
# Import everything needed to edit video clips from moviepy.editor import * import math
# loading video dsa gfg intro video clip = VideoFileClip("dsa_geek.webm")
# getting only first 5 seconds clip = clip.subclip( 0 , 5 )
# applying color effect final = clip.fl_time( lambda t: math.sin(t))
# setting duration final.duration = 9
# showing final clip final.ipython_display() |
Output :
Moviepy - Building video __temp__.mp4. Moviepy - Writing video __temp__.mp4 Moviepy - Done ! Moviepy - video ready __temp__.mp4
Another example
# Import everything needed to edit video clips from moviepy.editor import *
# loading video gfg clip = VideoFileClip("geeks.mp4")
# getting subclip from it clip = clip.subclip( 0 , 5 )
# altering time interval effect final = clip.fl_time( lambda t: 2 * t)
# setting duration final.duration = 10
# showing final clip final.ipython_display() |
Output :
Moviepy - Building video __temp__.mp4. MoviePy - Writing audio in __temp__TEMP_MPY_wvf_snd.mp3 MoviePy - Done. Moviepy - Writing video __temp__.mp4 Moviepy - Done ! Moviepy - video ready __temp__.mp4
