用Python剪辑制作简单视频(moviepy)

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")
