在python中使用日期列表为mp4视频添加时间戳/标签

pip install moviepy

from moviepy.editor import VideoFileClip
from moviepy.video.io.ffmpeg_tools import ffmpeg_extract_subclip
from datetime import datetime

# 定义日期列表
dates = ['2022-01-01', '2022-01-02', '2022-01-03']

# 读取视频文件
video = VideoFileClip("input.mp4")

# 计算每个时间戳的时间间隔
duration = video.duration / len(dates)

# 遍历日期列表
for i, date in enumerate(dates):
    # 将日期字符串转换为datetime对象
    date_obj = datetime.strptime(date, "%Y-%m-%d")
    
    # 计算时间戳的起始时间和结束时间
    start_time = i * duration
    end_time = (i + 1) * duration
    
    # 从视频中提取子剪辑
    subclip = video.subclip(start_time, end_time)
    
    # 添加时间戳/标签
    timestamp = date_obj.strftime("%Y-%m-%d")
    subclip = subclip.set_duration(duration).set_caption(timestamp)
    
    # 保存子剪辑为新的视频文件
    output_filename = f"output_{i}.mp4"
    subclip.write_videofile(output_filename)
