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

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

# 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
