Exif Not Updated - Error: [minor] Bad PreviewIFD offset for Nikon_PreviewIFD_0x0

[nikonexif]

Hello

I try to update all dates from the exif using the following command line :

Code Select Expand

exiftool "-AllDates+=0:00:00 01:00:00" -verbose *.jpg

For some pictures, that's OK, but i have a lot of error and the result is the following :

Code Select Expand

166 files weren't updated due to errors

If i look at the error i have :

Code Select Expand

Error: [minor] Bad PreviewIFD offset for Nikon_PreviewIFD_0x0007 - IMG_20210531_173133.jpg

Do you know how to solve this issue ?
I've try many action without success.
The only one which works was to open the file in Gimp and save it again.
But regarding the number of files ... that's not possible unless if you know how to do it with a command line.

Thank you

This is a destructive re-save and you have lost some of the image's data.  A better solution would be a program based upon jpegtran which does some lossless jpeg operations.  Under Windows, you could use Irfanview and it's Lossless Jpeg Plugin.  I mention this in case you have other problematic jpgs in the future that aren't fixable with exiftool.

With exiftool, as long as it isn't a RAW files such as a NEF, you could use FAQ #20 to try and repair the corrupted EXIF
