moviepy 提取音频

时间：2024-03-06 13:10:40
#pip install MoviePy

from moviepy.editor import *

video = VideoFileClip(\'F://a.mp4\')
audio = video.audio
audio.write_audiofile(\'F://dsa.mp3\')


# 从本地载入视频myHolidays.mp4并截取00:00:50 - 00:00:60部分
clip = VideoFileClip("D://a.mp4").subclip(50, 60)

# 调低音频音量 (volume x 0.8)
clip = clip.volumex(0.8)

# 把最后生成的视频导出到文件内
clip.write_videofile("D://myHolidays_edited.webm")

 

 

合并音频和视频以及插入文字和图片

from moviepy.editor import *
from moviepy.audio.fx import all

# 字体名字不能含有中文
FONT_URL = \'./font/heimi.TTF\'
def render(input_video, output_video="new_video.mp4"):
    # 剪个10s的720x1280px的视频
    background_clip = VideoFileClip(input_video, target_resolution=(720, 1280)).subclip(0, 10)
    # 音乐只要前10s
    audio_clip = AudioFileClip(\'yuna.mp3\').subclip(0,10)
    background_clip = background_clip.set_audio(audio_clip)
    # 左下角加文字, 持续10s
    text_clip1 = TextClip(\'aaa\', fontsize=30, color=\'white\', font=FONT_URL)
    text_clip1 = text_clip1.set_position((\'left\', \'bottom\'))
    text_clip1 = text_clip1.set_duration(10)
    # 右下角加文字, 持续3s
    text_clip2 = TextClip(\'我是右下角\', fontsize=30, color=\'white\', font=FONT_URL)
    text_clip2 = text_clip2.subclip(0, 3).set_position((\'right\', \'bottom\'))
    image_clip = ImageClip(\'shuoGG.png\')
    # 图片放中间, 从第2s开始播持续6s
    image_clip = image_clip.set_duration(6).set_position(\'center\').set_start(2)
    video = CompositeVideoClip([background_clip, text_clip1, text_clip2, image_clip])
    # # 调节音量
    video = all.volumex(video, 0.8)
    video.write_videofile(output_video)
    # background_clip.write_videofile(output_video)


if __name__ == \'__main__\':
    print(\'start!!!\')
    render(input_video="./模板.mp4", output_video="new_video.mp4")

这里面会遇到问题：

你得下载安装ImageMagick

安装的时候，安装过程注意勾选Install development headers and libraries for C and C++ 。

修改moviepy包（\Lib\site-packages\moviepy\）中的config_defaults.py文件，修改为

FFMPEG_BINARY = os.getenv(\'FFMPEG_BINARY\', \'ffmpeg-imageio\')
IMAGEMAGICK_BINARY = os.getenv(\'IMAGEMAGICK_BINARY\', \'auto-detect\')
IMAGEMAGICK_BINARY = r"G:\ImageMagick-7.0.9-Q16\magick.exe"
安装包我已经存在百度云了 ImageMagick-7.0.9-22-Q16-x64-dll.exe
