MoviePy – Changing Image and Time at same time of Video Clip

Last Updated : 01 Aug, 2020

In this article we will see how we can change display frames and time line of the video file clip in MoviePy at a same time. MoviePy is a Python module for video editing, which can be used for basic operations on videos and GIF’s. We use fl_image method to alter the display frames and fl_time method to alter the time, although we can do these task at a same time.

In order to do this we will use fl method with the VideoFileClip object
Syntax : clip.fl(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 *
  
   
# loading video dsa gfg intro video
clip = VideoFileClip("dsa_geek.webm")
   
# getting only first 5 seconds
clip = clip.subclip(0, 5)
  
def scroll(get_frame, t):
    """
    This function returns a 'region' of the current frame.
    The position of this region depends on the time.
    """
    frame = get_frame(t)
    frame_region = frame[int(t):int(t)+360, :]
    return frame_region
  
# alter time and frame
final = clip.fl( scroll )
  
# 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 duration of the video
duration = clip.duration
  
def scroll(get_frame, t):
    """
    This function returns a 'region' of the current frame.
    The position of this region depends on the time.
    """
    frame = get_frame(t)
    frame_region = frame[int(t):int(t)+360, :]
    return frame_region
  
# alter time and frame
final = clip.fl( scroll )
  
# showing final clip
final.ipython_display()

Output :
