HEIC Image Tags
« on: April 07, 2025, 03:16:59 pm »
Hello all,

I've found that MC won't update tags for heic files. These files are straight off an iPhone 3rd gen SE, nothing complicated. When I click Library Tools -> Update Tags (from Library), it simply reports that this failed, and indeed the tags are not in the file.

I've tried this in both MC29 and now MC33.

Update Tags works just fine for JPEGs. If I use MC to convert the HEIC file to JPEG format, tag updates works just fine. All other aspects of HEIC image handling (opening, reading phote date/time from the HEIC file) seem OK.

I've searched t'web for clues, nothing helpful that I've seen. Most results for MC seems to simply be the release notes suggesting HEIC image format is properly supported.

Anyone else having similar problems?

Thanks in advance!

Hello,

The tags I've tried to edit are Album, Places, and People.

I should have added that I'm on 33.0.71!

No, it's not write protected! (that would have been embarassing!)

I've turned on logging, and the following is showing up in the log file:

Code: [Select]

0388134: 8744: Database: CTagSaveInfo::GetSupportsTag: tagging of file D:\UserFiles\2025.03.28 16.14.12.heic is not supported.  local 1, cue file 0, media type Image DBLocation 3

I figured it out. There is indeed a problem.,

For now, you have a work-around:

Tools > Options > General > Importing & Tagging, set the following two options accordingly:

Sidecar tagging mode: Save in sidecar if internal tagging is not supported

Write to external sidecar files for media types: here you have four types - audio, video, data, image. Make sure Image is selected, along with any other types you choose.

Oh wow! I had no idea that external sidecars could be done for arbitrary file types!! I've seen them before for some video formats, but didn't know it could be turned on like this. That's an excellent work around and works just fine for what I need. Thank you very much  :)

Hmmm, strange things happening.

With the options set as you've indicated, I do not get a .xml sidecar file. Instead, it appears to be writing tags to the heic file itself. But, not all tags. It's putting in "Album" and "Person" Ok, but missing out "Places" (the file definitely has "Places" set in the library)!

I'm wondering if the lack of "Places" has anything to do with this page: https://wiki.jriver.com/index.php/Photo_Tagging , which states "MC saves IPTC tags, except for Places, to any JPEG it tags.". Mediatcenter puts "Places" in MJMD tags in JPEGs.

Here's the accompanying log activity:

And looking at the actual content of the heic file, there's this tacked on to the end:

Code: [Select]
<x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="XMP Core 6.0.0">

         <Iptc4xmpExt:PersonInImage>
            <rdf:Bag>
               <rdf:li>[Person's Name Redacted]</rdf:li>
            </rdf:Bag>
         </Iptc4xmpExt:PersonInImage>
         <photoshop:DateCreated>2025-03-28</photoshop:DateCreated>
      </rdf:Description>
   </rdf:RDF>
</x:xmpmeta>

It's interesting that the Album name is showing up in a field called "Event" in this xmpmeta data. That's a bit puzzling, because XMP stands for "Extensible Metadata Platform", meaning that any field imaginable could be added to it. But that's not (yet?) been exploited by Mediacenter.

You are welcome!

I've now opted for turning on Sidecar Tagging Mode: Save in both sidecar and internal tags (if supported). That gets me an external XML file, and that's achieving everything I need.

It'd be interesting to know if "that's it, end of the road" so far as internal arbitrary tags in heic files is concerned. It looks like it ought to be possible for it to put MJMD tags inside a heic file, just like it does with jpegs. That would solve everything. But I don't know for sure.

Thanks again for the help - it's pointed me towards a workable solutions, which is great :)

Regarding Places tag, we are treating it as a collection of information from other tags, Country, State/Provice, City, Sublocation etc.

Those individual tags are saved in XMP block and therefore there is no need to save Places separately. It is therefore a good idea you edit Country, City etc. instead of editing Places directly.
