Put "Last modified time" in Date exif

[JojoBernard]

Hello ,

I am new and it is complicated for me to understand because I 'm not English (and I know little :/).
I would take the image modification time and put in the date exif, but I do not know how the documentation is hard for me.

I know (for script/exiftool) :
Date (exif) = DateTimeOriginal
Date last modified = ModifyDate or FileModifyDate

like this ?

Code Select Expand

ExifTool "-DateTimeOriginal>FileModifyDate" C:\Users\account\Desktop\myPictures\*.jpg

Thx for help, I have to do that with 1100 Images

Image to understand :

Oh .. I found, it's simple haha

This code take the value of "datetimeoriginal" (exif) and put that value in "FileModifyDate"

Code Select Expand

ExifTool "-DateTimeOriginal>FileModifyDate" C:\Users\account\Desktop\myPictures\*.jpg


So I do the opposite direction to what I wanted

Code Select Expand

ExifTool "-FileModifyDate>DateTimeOriginal" C:\Users\account\Desktop\myPictures\*.jpg


but I have had mistakes and it did not work on some images



If you know why, thank you. I go to bed, it's late (4:00 am at home)

EDIT : We can do the same with the videos? (mp4)

Videos won't contain DateTimeOriginal, so you will probably have to use CreateDate instead.

Ok !
I'll see how to videos.
This is data that was on my phone (android) and some data were not DateTimeOriginal (exif) then the data had the date of transfer CreateDate  instead of the DateTimeOriginal (exif) and therefore misplaced in the gallery. I noticed that FileModifyDate matched DateTimeOriginal (exif).

By cons, this is the organization (hierarchical) my files:
"C:\Users\eleve\Desktop\fusion\" = Main Folder
"C:\Users\eleve\Desktop\fusion\AAAA\" (contains images)
"C:\Users\eleve\Desktop\fusion\BBBB\" (contains folders)
"C:\Users\eleve\Desktop\fusion\BBBB\ZZZZ" (contains images)
"C:\Users\eleve\Desktop\fusion\BBBB\YYYYY" (contains images)
"C:\Users\eleve\Desktop\fusion\BBBB\WWWW" (contains images + folder)
"C:\Users\eleve\Desktop\fusion\BBBB\WWWW\KKKKK"
"C:\Users\eleve\Desktop\fusion\CCCC\" (contains images + folder)
...

I have to do :

Code Select Expand

exiftool "-FileModifyDate>DateTimeOriginal" "C:\Users\eleve\Desktop\fusion\AAAA\*.jpg"
exiftool "-FileModifyDate>DateTimeOriginal" "C:\Users\eleve\Desktop\fusion\BBBB\ZZZZ\*.jpg"
exiftool "-FileModifyDate>DateTimeOriginal" "C:\Users\eleve\Desktop\fusion\BBBB\WWWW\*.jpg"
exiftool "-FileModifyDate>DateTimeOriginal" "C:\Users\eleve\Desktop\fusion\BBBB\WWWW\KKKKK\*.jpg"
exiftool -delete_original "C:\Users\eleve\Desktop\fusion\BBBB\WWWW\KKKKK\*.jpg"

There is a faster way to do this treatment in all folders in the folder main ?
exiftool "-FileModifyDate>DateTimeOriginal" "C:\Users\eleve\Desktop\fusion\ ALL FOLDERS ALL IMAGES
exiftool -delete_original "C:\Users\eleve\Desktop\fusion\ ALL FOLDERS

Try this:

Code Select Expand

exiftool "-FileModifyDate>DateTimeOriginal" -ext jpg -r -overwrite_original "C:\Users\eleve\Desktop\fusion"

Here is the command I used :

Code Select Expand

exiftool "-FileModifyDate>DateTimeOriginal" -ext jpg -ext jpeg -ext png -r -P -overwrite_original "C:\Users\eleve\Desktop\fusion"
It worked perfectly ! Except for png : "Creating non-standard EXIF in PNG".

Thank you for your help and for creating this program, it is really very useful. 

[Phil Harvey]

For PNG you should use CreationTime.  See the PNG Tags documentation for a complete list.

Thank you, That's perfect!

Here are the commands used for those wanting to make the same thing:

Code Select Expand

exiftool "-FileModifyDate>DateTimeOriginal" -ext jpg -ext jpeg -r -P -overwrite_original "C:\Users\eleve\Desktop\fusion"
exiftool "-FileModifyDate>CreationTime" -ext png -r -P -overwrite_original "C:\Users\eleve\Desktop\fusion"
