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
Python3
# Import everything needed to edit video clipsfrom moviepy.editor import * import math # loading video dsa gfg intro videoclip = VideoFileClip("dsa_geek.webm") # getting only first 5 secondsclip = clip.subclip(0, 5) # applying color effectfinal = clip.fl_time(lambda t: math.sin(t))# setting durationfinal.duration = 9# showing final clipfinal.ipython_display() |
Output :
Moviepy - Building video __temp__.mp4.
Moviepy - Writing video __temp__.mp4
Moviepy - Done !
Moviepy - video ready __temp__.mp4
Another example
Python3
# Import everything needed to edit video clipsfrom moviepy.editor import *# loading video gfgclip = VideoFileClip("neveropen.mp4")# getting subclip from itclip = clip.subclip(0, 5) # altering time interval effectfinal = clip.fl_time(lambda t: 2 * t)# setting durationfinal.duration = 10# showing final clipfinal.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
