Error/Warning Explanations (APP1 , EOI, Photoshop)

[BJ1200]

Hi guys,

I have several thousand JPG images to clean up metadata. Using 8.74 (win7-64) the app would freeze at the very end and not generate the log showing problem images. Upgrading to 8.84 fixed this. (I use the GUI). I end up having about 150 images that produce errors. Which errors/warnings should I worry about? What do they mean?

Error: JPEG EOI marker not found - image1.jpg
Warning: [minor] Ignored APP1 XMP segment with non-standard header - image2.jpg
Warning: Multiple Photoshop records - image3.jpg

I've been converting all problem images to JPG again which seems to clean up the issues. I can then remove the metadata. This is a painfully slow process finding each problem image in a folder of 30,000 and moving them to a processing folder. Any suggestions?

The missing JPEG EOI error is serious, and indicates a corrupted image.

The warnings in your example both indicate problems in the metadata written by non-compliant software.

Although the warnings when writing are not exactly the same as when reading (because more checks are done when writing), you can find most of the images with warnings like this:

exiftool -p "$directory/$filename" -if "$warning" -r DIR

This command will print the directory and file name of images with warnings in directory DIR.  (Mac/Linux users: Use single quotes instead of double.)

thanks Phil. I did look in the metadata and couldn't see anything unusual. Many had a thumbnail that was half gray, but the full size image was OK. I converted all the images to JPG's again which seemed to fix them, no more errors.
