Help with MakerApple metadata
« on: March 19, 2015, 12:10:48 PM »

On a photo taken with the iPhone 6 in "Burst Mode" I've found it creates a metadata group called {MakerApple} and a unique UUID is adde to a key 11.  I'm hoping to manually add UUID's to metadata on non-iPhone sourced photos to fool Photos.app and the iPhone into grouping them into a Burst.  Can anyone tell me if exiftool can help or do this?  I can generate a unique UUID easily on my Mac, I just need the ability to write the metadata.  Thanks

{MakerApple}

I can answer this if you can send me a sample of a burst-mode image (my email is philharvey66 at gmail.com), so I can see how this information is stored.

... (still waiting.  I expect the mail is delayed due to the darned QueensU mail greylisting.  You can resend to bypass this.)

Currently, you can use ExifTool to copy the entire makernote block between images, which may help you out, but it can't be used to write a new UUID (the unknown "Apple 0x000b" tag), so you would be stuck effectively copying UUID's from existing images.

I will add support for reading/writing this to ExifTool 9.91 (with a tag named "BurstUUID"), so with this version you will be able to change this UUID in an image that already contains it.

If you can decode the meaning of any of the other unknown tags, please let me know.

Thank you very much Phil for taking the time to look at this!  I'll see if I can figure out what the other metadata means.

The -BurstUUID works great on images taken from my iPhone but not from my GoPro (i'm trying to make burst groups from some vacation pictures so they look better when browsing them on my phone).

When I try to use the "-BurstUUID=" option on the GoPro image the following happens:

Code: [Select]
exiftool -v -overwrite_original -m -P "-makernotes:apple:burstuuid=$UUID" G0232134.JPG

But when I copied the tags over from an iPhone image it worked

Is there a way to set the -BurstUUID option on any photo without copying in MakerNotes from another image?

No.  Makernote tags may not be created individually. They may only be changed if they already exist.  The only way to create them is to copy the entire makernotes as a block.  I suggest maybe creating a user-defined XMP tag instead, and writing this to your GoPro images.
