MoviePy – Resizing Video File

Difficulty Level : Basic
Last Updated : 01 Aug, 2020

In this article we will see how we can resize 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. Resizing video file means. Image/frame interpolation occurs when you resize or distort your frame of vdideo from one pixel grid to another. Video resizing is necessary when we need to increase or decrease the total number of pixels, whereas remapping can occur when you are correcting for lens distortion or rotating an video.

In order to do this we will use resize method with the VideoFileClip object

Syntax : clip.resize(n)

Argument : It takes float value i.e multiplier
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 and getting only first 5 seconds
clip1 = VideoFileClip("dsa_geek.webm").subclip(0, 5)
  
# getting width and height of clip 1
w1 = clip1.w
h1 = clip1.h
  
print("Width x Height of clip 1 : ", end = " ")
print(str(w1) + " x ", str(h1))
  
print("---------------------------------------")
  
  
# resizing video downsize 50 % clip2 = clip1.resize(0.5)
  
# getting width and height of clip 1
w2 = clip2.w
h2 = clip2.h
  
print("Width x Height of clip 2 : ", end = " ")
print(str(w2) + " x ", str(h2))
  
print("---------------------------------------")
  
  
  
# showing final clip
clip2.ipython_display(width = 480)

Output :

Width x Height of clip 1 :  854 x  480
---------------------------------------
Width x Height of clip 2 :  427 x  240

Another example

# Import everything needed to edit video clips
from moviepy.editor import *
  
# loading video gfg
clip = VideoFileClip("geeks.mp4")
  
# getting subclip
clip1 = clip.subclip(0, 7)
  
# getting width and height of clip 1
w1 = clip1.w
h1 = clip1.h
  
print("Width x Height of clip 1 : ", end = " ")
print(str(w1) + " x ", str(h1))
  
print("---------------------------------------")
  
  
# resizing video downsize 50 % clip2 = clip1.resize(0.5)
  
# getting width and height of clip 1
w2 = clip2.w
h2 = clip2.h
  
print("Width x Height of clip 2 : ", end = " ")
print(str(w2) + " x ", str(h2))
  
print("---------------------------------------")
  
  
  
# showing final clip
clip2.ipython_display()

Output :

Width x Height of clip 1 :  656 x  404
---------------------------------------
Width x Height of clip 2 :  328 x  202
