我如何找到实际录制视频(.AVI .MP4)的日期? [英] how do i find the date a video (.AVI .MP4) was actually recorded?

问题描述

properties>日期已创建...我认为这意味着创建视频的日期，但最终意识到，每次我移动，重组甚至打开文件时，日期都会更改.通常，修改日期早于创建日期.拍摄jpeg的日期随时可用.有什么办法可以从AVI或MP4文件中获取相同的信息? 感谢您提供的任何信息.

properties> date created... i thought this meant the date the video was created, but finally realized that date changes every time i move, reorganize, even open a file. often, the date modified is earlier than date created. the date a jpeg was taken is readily available. is there any way to get the same information from an AVI or MP4 FILE? thank you for any information you can give.

用于在许多视频文件中查找日期/时间元数据的快速命令

以下命令在查找各种AVI/MP4视频上的日期/时间元数据方面非常有用:

Quick Command for Finding Date/Time Metadata in Many Video Files

The following command has served me well in finding date/time metadata on various AVI/MP4 videos:

ffmpeg -i /path/to/video.mp4 -dump

注意:如其他答案所述，不能保证此类信息在所有视频文件中可用或以特定格式提供.

Note: as mentioned in other answers, there is no guarantee that such information is available in all video files or available in a specific format.

    Metadata:
      Make            : FUJIFILM
      Model           : FinePix AX655
      DateTime        : 2014:08:25 05:19:45
      JPEGInterchangeFormat:     658
      JPEGInterchangeFormatLength:    1521
      Copyright       :     
      DateTimeOriginal: 2014:08:25 05:19:45
      DateTimeDigitized: 2014:08:25 05:19:45

某些MP4文件的缩写示例输出

  Metadata:
    major_brand     : mp41
    minor_version   : 538120216
    compatible_brands: mp41
    creation_time   : 2018-03-13T15:43:24.000000Z
