python 进行视频剪辑

• 导入所需的python库

import os
from moviepy.editor import *
from pydub import AudioSegment
# video = VideoFileClip("./test.mp4")

1 提取背景音乐

video = VideoFileClip("./test.mp4") # 读取数据
audio = video.audio   # 获取视频的音频
audio.write_audiofile(\'./test.wav\') # 将音频以.wav格式保存

2 去掉视频的背景音乐，只保留视频文件

video = VideoFileClip("./small.mp4") # 读取数据
audio = video.without_audio()   # 去掉视频的音频
audio.write_videofile(\'./test1111.mp4\') # 保存视频

3 视频剪辑

• 剪切视频，假设截取前20秒

video = VideoFileClip("./test.mp4") # 读取数据
video = video.subclip(0,20) # 设置截取数据的范围
video.to_videofile("./small.mp4") # 保存数据

4 视频拼接

# # 定义一个数组
# L = []
#
# # 合并少量视频
# video1 = VideoFileClip(\'./test.mp4\')
# L.append(video1)
# video2 = VideoFileClip(\'./small.mp4\')
# L.append(video2)

5 视频倍速播放

# 对视频进行加速
# video= \'./small.mp4\'
# resultFile= \'./result.mp4\'
# video = VideoFileClip(video)
# duration = video.duration
# video = video.fl_time(lambda t: 1.1*t,
#               apply_to=[\'video\',\'audio\']
#               ).set_end(duration/1.1)
# video.write_videofile(resultFile)
# from  moviepy.editor import *
#
# clip = VideoFileClip(r"./small.mp4")
# clipSpeed = clip.speedx(1.1)
# clipSpeed.write_videofile(r"./result.mp4")
