Difficulty removing metadata even when doing a replace with a different metadata template

[paulc65657246]

Hi everyone,

I am tearing my hair out because I can't seem to overwrite a metadata file.  I have created a new one and then try to replace and overwrite the previous details, but it still keeps the old camera EXIF data and not the new one which I require.

Does this have anything to do with Document Ancestors? Do I have to run some kind of script to get rid of old data?

I have been on this for days now and it is getting me frustrated. Hope someone can help. Thank you.

Best regards Paul

I'll take a look at it. This was one I wrote to solve a problem I was having so it's not really well tested.

I'm having a similar problem and I believe I have found a bug in the export process. I'm trying to remove all Meta data from the Exported file. If I use the Meta Off export profile, as is, the Camera data (Exif) is removed including the serial number of the camera. If I make a copy of the Meta Off profile and change the profile to Export the file with Long Edge as 3840, the Camera data is exported in the file. I think Export has a bug that includes Camera data when trying to resize the image.

The technique that works for me is to export using Meta Off, full size, and then Export the entire Meta Off directory a second time resizing to 3840. Since the JPEGs in the Meta Off file do not have the camera data, neither do the resized images.

This is frustrating because it wastes a lot of disk space and time. I'm hoping someone from Adobe can test this and fix this issue.
