把玩了下moviepy蛮有意思的, 记录下来方便以后使用

(ps: 其实直接看官网就可以无视该教程了: https://pypi.python.org/pypi/moviepy)

1. 环境

(1) pip install moviepy

(2) 安装 ImageMagick, http://www.imagemagick.org/script/download.php

如果是windows玩家直接在这里下个最新的exe安装, 安装包在此, 安装完后设置环境变量: IMAGEMAGICK\_BINARY 的值为convert.exe的路径;

(3) python工程根目录建个"ffmpeg"文件夹, 然后把"ffmpeg.win32.exe"丢进去, 记住名字必须为"ffmpeg.win32.exe";

2. 实例代码

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('我是左下角', 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)  
  
  
if \_\_name\_\_ == '\_\_main\_\_':  
print('start!!!')  
render(input\_video="./模板.mp4", output\_video="new\_video.mp4")
