MoviePy – Assigning Audio Clip to Video File

In this article we will see how we can add external audio to 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. Video is formed by the frames, combination of frames creates a video each frame is an individual image. An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression. We can load the audio file with the help of AudioFileClip method.

In order to do this we will use set_audio attribute with the video file clip object

Syntax : clip.set_audio(audio)

Argument : It takes AudioFileClip object 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.mp4")


# getting only first 5 seconds
clip = clip.subclip(0, 5)

# loading audio file
audioclip = AudioFileClip("allwell.mp3").subclip(0, 5)

# adding audio to the video clip
videoclip = clip.set_audio(audioclip)

# showing video clip
videoclip.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

Another example

# Import everything needed to edit video clips
from moviepy.editor import *

# loading video gfg
clip = VideoFileClip("geeks.mp4")

# getting only first 5 seconds
clip = clip.subclip(0, 5)

# loading audio file
audioclip = AudioFileClip("allwell.mp3").subclip(0, 5)

# adding audio to the video clip
videoclip = clip.set_audio(audioclip)

# showing video clip
videoclip.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 !
