使用 moviepy 将音频添加到视频

Question

Title basically explains it. Trying to add audio to a video. I have a sequence of mp3 files that I want to play sequentially during the video. There're no errors or anything with the code but when I run the code theres still no audio in the video. Just a recreation of the old video with no audio (the original video doesnt have audio either).

video = VideoFileClip("finished_video.mp4")
title_clip = AudioFileClip("title.mp3")

audio_list = [title_clip]

for x in range(1, counter):
    audio = AudioFileClip("p{}.mp3".format(x))
    audio_list.append(audio)

video.set_audio(audio_list)
video.write_videofile("new_filename.mp4")

Answer 1

it works for me

from moviepy.editor import *
videoclip = VideoFileClip("sample.mp4")
audioclip = AudioFileClip("sample_audio.mp3")

new_audioclip = CompositeAudioClip([audioclip])
videoclip.audio = new_audioclip
videoclip.write_videofile("output.mp4")

use CompositeAudioClip to merge both files.

Answer 2

I had the same issue. It seems like set_audio() doesn't actually set it, but returns the new video combined with the audio.

This is the way I did it:

final_video = video.set_audio(audio_list)
final_video.write_videofile("new_filename.mp4")

Hope that helps !
