Python---批量给视频添加片头片尾

news 2026/5/11 17:46:42

在剪辑视频的时候，如果视频很少的情况可以考虑自己使用软件来拼接一下，但是如果要给几百个视频加片头片尾，那就需要使用软件来加了。

基础代码示例：

from moviepy.editor import VideoFileClip, concatenate_videoclips# 读取三段视频
piantou = VideoFileClip("piantou-10000k-25f.mp4")
video = VideoFileClip("video.mp4")
pianwei = VideoFileClip("pianwei-10000k-25f.mp4")
# 拼接并导出
outvideo = concatenate_videoclips([piantou, video, pianwei])
outvideo.write_videofile("outvideo.mp4")

这种方式可以给一个视频添加片头片尾。

批量给视频视频添加片头片尾：

import os

import time
import subprocess
from multiprocessing import Pool
from typing import List, Dict# 配置路径
INPUT_VIDEO_DIR = r"E:\python-test\视频处理\原视频"  # 原视频文件夹
OUTPUT_VIDEO_DIR = r"E:\python-test\视频处理\带片头片尾视频"  # 输出文件夹
OPENING_VIDEO = r"E:\python-test\视频处理\piantou-tongyi.mp4"  # 片头视频路径
ENDING_VIDEO = r"E:\python-test\视频处理\pianwei-tongyi.mp4"  # 片尾视频路径# 支持的视频格式（可扩展）
