Tahoe Finder Missing Video Duration in Detailed Info

I have a new external harddrive that is mentioned to be for Macs, I didn't suspect that to cause any issues, but at this point it is a possibility. If I transferred the files from my internal to that external, it is possible that that meta data was deleted at that point.

Only if the drive was formatted ExFAT or something that doesn't have resource forks. macOS will split off the metadata into ._ files so that they can be reattached to the file if copied back to a Mac formatted drive.

Though when downloading a new .mp4, I don't see the duration so that removes that possibility.

Unless of course there is something wrong with that website's data.

I had created some movies in Adobe Premier Pro and the duration doesn't show up for those, but can't say if that is the same issue or it's something with Adobe. That is likely what made Apple support think it was something on Adobe's end.

I don't think me having an M1 chip would make a difference compared to the newer models either. Only thing I can really think of is there was an issue during installation.

See my updates on the last post. I think there is something wrong with the metadata importer or with how the data is handled when imported. It seems that mdimport finds the data, but it doesn't get written to the macOS metadata.

Since the Tahoe update, I've also been having problems with video metadata. I always use Finder in column view with a preview column. Before the Tahoe update, all metadata, including duration and codec, was visible in the preview column under the video thumbnail. Now, only filename, MPEG-4 movie, size, Created, Edited, and Opened are visible.

When I open the preview options and check all the options, the metadata titles with empty values ​​appear in the preview column. When I close the preview options window, the metadata titles with empty values ​​disappear from the preview column.

Indeed, this is also the case for me. All the metadata for all the videos on my external and internal drives has disappeared after Spotlight indexing.

And I'm not just talking about the duration, but also about codec and dimensions, among other things. I can retrieve this information with other apps, such as Scoop.

No metadata is added to new videos.

I have a Mac Mini M2.

Yes, but I'm not sure that it entirely deletes the metadata, since other apps—Invisor, a MediaInfo-based app, for example, or as someone pointed out above, Quicktime—can still show those attributes.

But they're definitely stripped from wherever Finder stores its metadata—I'm guessing the Spotlight index, since others said re-indexing led to that info disappearing.

Someone who knows more about file systems will be able to answer this—but my guess is that it's something that can be fixed in the OS, and that once it has been, Finder will again show those attributes, even for files which don't appear to have them now.

I have the same problem and for those people saying they don’t have the issue, you just might not realize it. Most of my videos had the metadata when I first updated but when I added new videos I noticed it wasn’t showing things like duration or other info. So I had Spotlight re-index my drive and that’s when it disappeared for all my videos. So I suggest downloading a new video and see if the info is there to see if you have the issue.

I have Tahoe 26.0 on an M4 Mac Mini and after the Tahoe 26 update I have the same issue as everyone else here.

MP4 data for Dimensions and Duration are missing in Get Info.

Some videos did have them, but after I reset spotlight they lost the data aswell.

this is serious issue for me as I need to organise and search videos by duration and resolution all the time.

If it helps any, you're correct. Sequoia shows the Duration, Tahoe doesn't.

edit: at least for the mp4 files I have.

The duration is in kMDItemDurationSecond

FWIW, in Tahoe, when I run the Terminal command on various mp4s, kMDItemDurationSecond is not listed.

Thanks. Would seem to be a Finder bug, then. I prefer that to an Apple decision since it means it will hopefully be fixed in a point update.

I have Tahoe 26.0 on an M4 Mac Mini. Every .mp4, .m4v, and .mov video that I select in the Finder's Get Info panel displays a duration value. Even the codec information if available:

Duration information will not be shown for the Matroska (.mkv) video file format, nor .avi movies.

Same here. The only way I see dimensions and duration is by playing the video and then seeing it in the Software playing - so playing in QuickTime and then showing it.

A major issue.

Anyone tried reinstalling Mac OS Tahoe to see if it fixes it?

It is so bad, because you cannot even do Advanced Search based on Duration, Dimensions and Bit Rate either now after Tahoe.

If it was deliberate then they would have removed the drop down option in Advanced Finder search for these instead of it just giving no results.
