moviepy 提取音频(moviepy 转场)
#pip install MoviePyfrom moviepy.editor import *video = VideoFileClip('F://a.mp4')audio = video.audioaudio.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
