## 场景 ##

moviepy官网：

[https://pypi.org/project/moviepy/][https_pypi.org_project_moviepy]

是一个用于视频编辑的Python库：切割、连接、标题插入、视频合成、非线性编辑，视频处理和定制效果的创建。

## 实现 ##

首先你需要安装moviepy

打开cmd输入:

pip install moviepy

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70][]

其次需要安装ffmpeg,因为网络问题，这里使用豆瓣镜像

pip install imageio-ffmpeg -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 1][]

如果之前那么没有安装过PyQt5,你还需要：

pip install PyQt5 -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

然后新建python文件，输入代码

import imageio
    imageio.plugins.ffmpeg.download()
    import win_unicode_console
    win_unicode_console.enable()
    import sys,os
    from PyQt5.QtCore import *
    from PyQt5.QtWidgets import (QWidget, QPushButton, QLineEdit,QLabel,
                                  QApplication,QFileDialog)
    from moviepy.video.io.VideoFileClip  import VideoFileClip
    
    
    class login(QWidget):
        def __init__(self):
            super(login,self).__init__()
            self.initUI()
    
        def initUI(self):
            #源文件选择按钮和选择编辑框
            self.source_btn = QPushButton('源文件', self)
            self.source_btn.move(30, 30)
            self.source_btn.resize(60,30)
            self.source_btn.clicked.connect(self.select_source)
            self.source_le = QLineEdit(self)
            self.source_le.move(120, 30)
            self.source_le.resize(250,30)
    
            # 存储文件选择按钮和选择编辑框
            self.target_btn = QPushButton('目标路径', self)
            self.target_btn.move(30, 90)
            self.target_btn.resize(60, 30)
            self.target_btn.clicked.connect(self.select_target)
            self.target_le = QLineEdit(self)
            self.target_le.move(120, 90)
            self.target_le.resize(250, 30)
    
            #截切开始时间输入框和提示
            self.startLabel = QLabel(self)
            self.startLabel.move(30, 150)
            self.startLabel.resize(60,30)
            self.startLabel.setText("开始秒")
            self.start_le = QLineEdit(self)
            self.start_le.move(120,150)
            self.start_le.resize(50,30)
    
            # 截切结束时间输入框和提示
            self.stopLabel = QLabel(self)
            self.stopLabel.move(230, 150)
            self.stopLabel.resize(60,30)
            self.stopLabel.setText("结束秒")
            self.stop_le = QLineEdit(self)
            self.stop_le.move(320,150)
            self.stop_le.resize(50,30)
    
            #保存按钮，调取数据增加函数等
            self.save_btn = QPushButton('开始',self)
            self.save_btn.move(30, 210)
            self.save_btn.resize(140, 30)
            self.save_btn.clicked.connect(self.addNum)
    
    
    
            #执行成功返回值显示位置设置
            self.result_le = QLabel(self)
            self.result_le.move(30, 270)
            self.result_le.resize(340, 30)
    
    
            #整体界面设置
            self.setGeometry(400, 400, 400, 400)
            self.setWindowTitle('视频剪切')#设置界面标题名
            self.show()
    
        # 打开的视频文件名称
        def select_source(self):
            target,fileType = QFileDialog.getOpenFileName(self, "选择源文件", "C:/")
            self.source_le.setText(str(target))
        #保存的视频文件名称，要写上后缀名
        def select_target(self):
            target,fileType = QFileDialog.getSaveFileName(self, "选择保存路径", "C:/")
            self.target_le.setText(str(target))
    
    
        def addNum(self):
            source = self.source_le.text().strip()#获取需要剪切的文件
            target = self.target_le.text().strip()#获取剪切后视频保存的文件
            start_time = self.start_le.text().strip()#获取开始剪切时间
            stop_time = self.stop_le.text().strip()#获取剪切的结束时间
            video = VideoFileClip(source)#视频文件加载
            video = video.subclip(int(start_time), int(stop_time))#执行剪切操作
            video.to_videofile(target, fps=20, remove_temp=True)#输出文件
            self.result_le.setText("ok!")#输出文件后界面返回OK
            self.result_le.setStyleSheet("color:red;font-size:40px")#设置OK颜色为红色，大小为四十像素
            self.result_le.setAlignment(Qt.AlignCenter)#OK在指定框内居中
    
    if __name__=="__main__":
        app = QApplication(sys.argv)
        ex = login()
        sys.exit(app.exec_())
