Trying to fix metadata warning (tip 20) not working.

[sebutzu]

OS: Windows 10/ 64bit, Ver: 11.10, Calling from C# using ExifToolWrapper.cs with some changes, exiftool started with stay open and params:

-fast  -m -q -q -stay_open True -@ - -common_args -d \"%Y.%m.%d %H:%M:%S\" -c \"%d %d %.6f\" -t -s -G -a

then calling:


-all=
-tagsfromfile
@
-all:all
-unsafe
-icc_profile
-P
-m
-overwrite_original
E:\Work\test.jpg


(plus execute...)

results in:

Code Select Expand


    1 image files updated


The warning from the file is:

Code Select Expand

Invalid CanonAFInfo data

It remains the same after the command is run. Expected - to fix the problematic tags.

Attached is a sample image (but I have a lot of them).

Also running exiftool directly:
"exiftool(-k).exe" -all= -tagsfromfile @ -all:all -unsafe -icc_profile -F -a "E:\Work\test.jpg"

results in

Code Select Expand

Warning: Invalid CanonCameraSettings data - E:/Work/test.jpg
Warning: Invalid CanonShotInfo data - E:/Work/test.jpg
Warning: Invalid CanonAFInfo data - E:/Work/test.jpg
    1 image files updated

but the file stays the same (with same errors).

How can I get rid of the errors?

Thanks for this report.

Unfortunately ExifTool can't fix everything.  The only way to get rid of this particular error is to delete the makernotes entirely.

Note that you should not get an error like this when running ExifTool on an original file straight from the camera.  If you do, then I would like to know about it.
