如何使用 exiftool 为目录中的所有图像添加 subsecdatetimeoriginal？

[英]How to add subsecdatetimeoriginal for all images in a directory using exiftool?

 原文  2022-05-08 10:43:12  4   1    exiftool

问题描述

If i use below command then i get Warning: No writable tags set如果我使用下面的命令然后我得到Warning: No writable tags set

exiftool '-subsecdatetimeoriginal+<0:0:0${filesequence;$_*=0.500}' -overwrite_original ./images

and if i do:如果我这样做：

exiftool '-datetimeoriginal+<<0:0:0${filesequence;$_*=0.500}' -overwrite_original ./images

This is changing the date and time part correctly but not updating the millisecond part for SubSecTimeOriginal这是正确更改日期和时间部分但不更新SubSecTimeOriginal的毫秒部分

so if first image has SubSecTimeOriginal=100 then all images have same value when it should all be different.因此，如果第一张图像具有SubSecTimeOriginal=100 ，则所有图像都具有相同的值，但它们应该都不同。

The SubSecDateTimeOriginal tag is not a tag that is actually embedded in the file, but is instead a Composite tag that exiftool creates on the fly while reading/writing. SubSecDateTimeOriginal标签不是实际嵌入文件中的标签，而是 exiftool 在读取/写入时即时创建的复合标签。 This tag is cannot be shifted and unfortunately, there isn't a warning about this unless you add the -v3 ( -verbose3 ) option , where it will say Composite:SubSecDateTimeOriginal is not shiftable .这个标签不能被移动，不幸的是，没有关于这个的警告，除非你添加-v3 ( -verbose3 ) 选项，它会说Composite:SubSecDateTimeOriginal is not shiftable 。

A workaround would be to use an XMP date/time stamp tag, as they can contain the full time value (subsecond and time zone), unlike EXIF time tags which are split into three separate tags.解决方法是使用 XMP 日期/时间戳标签，因为它们可以包含完整的时间值（亚秒和时区），这与 EXIF 时间标签不同，EXIF 时间标签分为三个单独的标签。 XMP:DateTimeOriginal would be the most suitable tag. XMP:DateTimeOriginal将是最合适的标签。

If it's not already set, you would first copy the time from SubSecDateTimeOriginal .如果尚未设置，您将首先从SubSecDateTimeOriginal复制时间。 Then you would run your command to increment the time stamp.然后你会运行你的命令来增加时间戳。 Finally, you would copy the XMP:DateTimeOriginal back into SubSecDateTimeOriginal .最后，您可以将XMP:DateTimeOriginal复制回SubSecDateTimeOriginal 。
