I would much appreciate your experience with metadata.
Purpose is to make dual fisheye 7776x3338 photos accepted by stitching software for stitching. Presently the 5792x2896 photos are stitched successfully. The stitching software was originally designed to stitch 7776x3338 photos and now does not.
I converted a 7776x3338 photo to 5792x2896 then copied the metadata from an example 5792x2896 on to the resized photo.
The resized injected image is not being stitched by the software.
I used the following script:
Set "AA=C:\Exiftool\Temp_Image\360_00ph_meta.jpg" ::XMP source file, full address
set "G=360_0001.jpg"
ffmpeg -i %G% -vf scale=5792:2896 -y NewSizePhoto.jpg
REM Copy all metadata to the New Size Photo
exiftool -TagsFromFile %AA% "-all:all>all:all" NewSizePhoto.jpg
Example photos are:

and other 5792x2896 photo

I don't have any idea what metadata your stitching software requires, so I can't help much here. Maybe try comparing the metadata from an image that works in your stitching software to one that doesn't.

Your original images are MPF (Multi-Picture Format) (https://exiftool.org/TagNames/MPF.html) but ffmpeg is creating a simple jpg image. You're losing all the MPF images in the conversion.
