Title: Help please! Maker notes offsets
Post by: Redbill73 on March 10, 2022, 12:31:50 PM
Hello! I am using the following string to update my photos but I face a problem with some of them.

exiftool -r -charset filename=cp1253 "-overwrite_original" "-DateTimeOriginal<${Filename;m/(\d{4}-\d\d-\d\d)/;$_=$1} 00:00:00" "-Subject<${Basename;m/ (.+) \d/;$_=$1}" "-Description<${Basename;m/ (.+) \d/;$_=$1}" "-imageDescription<${Basename;m/ (.+) \d/;$_=$1}" c:\path

It gives me the following message and does not update.

Possibly incorrect maker notes offsets (fix by 482?)

The 482 could be any number. Can somebody help?

See FAQ #15 (https://exiftool.org/faq.html#Q15) and FAQ #20 (https://exiftool.org/faq.html#Q20).

Make sure you have proper backups in case something goes wrong, as you're making significant change to the file.  Then run this command from FAQ #20 (do not run it on Tiff or RAW files)
