How do I use milliseconds when renaming files?

[Phil Harvey]

Hi Uwe,

Leading zeros are significant in SubSecTimeOriginal.  ("01" is 0.01 sec, while "001" is 0.001 sec.)  So you change the value if you pad with leading zeros.

You should pad with trailing zeros as in my post. ("010" is still 0.01 sec.)

Hi Phil,
thanks for your very fast respond.
These are the tags in the photos:
Sub Sec Time Digitized           8
Sub Sec Time Digitized           01
Sub Sec Time Digitized           14
Sub Sec Time Digitized           31
Sub Sec Time Digitized           64
After the rename I get these files and this sort(depending on ascending or descending):
20160115_170512-800.dng
20160115_172612-010.dng
20160115_172612-140.dng
20160115_172612-310.dng
20160115_172612-640.dng
My problem are the values "8" and "01" written by the camera. Following your explanation: 8=0,8s, 01=0,01, ...64=0,64s. In this case the problem is the sort of the Windows file system and other applications.
Regards, Uwe

Hi Uwe,

The sort order looks fine to me (the minutes are different for the "800" file).

Hi Phil,
sorry, I was so focussed on the ms that I didn't see the wood for the trees.

Hi,

Sorry to dig out this old topic, but I just can't make this function work.

exiftool -d %Y-%m-%d-%H-%M-%S%%c.%%e "-filename<datetimeoriginal" DIR
works fine and brings out this result: 2017-07-08-14-46-08.RW2

So, how do I add this string: ${subsectimeoriginal;$_.=0 x(3-length)} to get the format:
2017-07-08-14-46-08-000.RW2 ?

Thanx in advance

[Phil Harvey]

Try this:

exiftool -d %Y-%m-%d-%H-%M-%S "-filename<${datetimeoriginal}-${subsectimeoriginal;$_.=0 x(3-length)}%-c.%e" DIR

Apologies for the old thread, but is it possible to pad with zeros in front of the tag? Specifically, for example, for episode numbers to show as 01, 02, 03, 04, etc.?

[Hayo Baan]

Yes, that's actually what Phil's last command does. But if you show us what you are now using as rename string and where you'd like to see the leading zeros, we could give you the exact command to use.

[RPSM]

This may seem dumb, but once it clicked it was "just Perl", I got it. I now use this:

exiftool '-testname<${tvshow}-S${tvseason;$_=sprintf("%02d",$_)}.E${tvepisode;$_=sprintf("%02d",$_)}.%e' rename.mp4

work's incredibly. Thanks for the "push".

Dear Phil,

I have some tif files, that are using subsectimeoriginal tag, but not with all digits.
Sub Sec Time Original           : 7

So the following command, does not work correctly
exiftool -v '-Filename<${datetimeoriginal}--${subsectimeoriginal;$_.=0 x(3-length)}.%e' -d %Y-%m-%d__%H-%M-%S .

How can I prepend zeros, instead of appending and rewrite subsectimeoriginal tag?
Sub Sec Time Original           : 7    -> Sub Sec Time Original           : 07


2021-01-20__14-23-45--700.tif (wrong)
2021-01-20__14-23-45--007.tif (would be correct)

exiftool ./2021-01-20__14-23-45--700.tif | grep -i time
File Modification Date/Time     : 2021:06:11 15:05:33+02:00
File Access Date/Time           : 2021:06:11 15:05:33+02:00
File Inode Change Date/Time     : 2021:06:11 15:16:52+02:00
Date/Time Original              : 2021:01:20 14:23:45
Sub Sec Time Original           : 7
Date/Time Original              : 2021:01:20 14:23:45.7


Thank you,
Cheers Martin

Greetings Martin, please to experiment with something like... ${subsectimeoriginal; s/^(\d)$/00$1/; s/^(\d\d)$/0$1/} but not needing the spaces.
Its replacing (only-1Digit) with 001Digit, then its replacing (only-2Digits) with 02Digits

[Phil Harvey]

To prepend zeros:  ${subsectimeoriginal;$_=0 x (3-length).$_}

But I think this is wrong.  A SubSecTimeOriginal of "3" means 0.3 seconds.
