Welcome folks today in this blog post we will be using the moviepy
library to change opacity
or apply color filter
inside mp4 video
in command line. All the full source code of the application is shown below.
Get Started
First of all we need to install the below moviepy
library using the pip
command as shown below
pip install moviepy
In order to get started you need to make an app.py
file and copy paste the following code
app.py

# Import everything needed to edit video clips from moviepy.editor import * # loading video gfg clip = VideoFileClip("video.mp4") # getting subclip from it clip = clip.subclip(0, 9) # applying color effect final = clip.fx( vfx.colorx, 0.3) # showing final clip final.ipython_display() |
As you can see we are importing the moviepy
library at the very top and then we are only taking the first 9
seconds of the input video using the subclip()
method and then we are applying the color
effect or changing the opacity
of the video using the fx()
method and inside it we are providing the numerical
value if the value is larger then the opacity of the video will increase. And if the value is closer to 0
then the video will be more black
in color as shown below
