P: (Z9) Embedded previews are missing on a few images on large imports

I have been doing bird photography and importing hundreds of images, and I rely on Embedded Previews for my intial triage/culling. I have ALL of the options for replacing embedded previews disabled (Idle time, etc).

Yesterday, I imported 1400 photos into my Lr 11.2 catalog, and Lr built Standard Previews for every file.

Sometimes, it leaves me a few Embedded Previews, but this is maddening. 

 

The Embedded Preview feature is ideal for those of us who need to triage quickly, including viewing images at 1:1.

 

Not sure if there's something I'm missing, or if this is a bug in Lr 11.

    2024 March - Problem still persists. 

    How much time does Adobe need to fix a bug?
    If you ever wonder why you are loosing clients, painful culling process is defo one of the reasons.

    I can confirm the same issue Jason is describing on the Nikon Z8. Same process he is describing for bird photography and have neved had this issue with Nikon D500, D750, D300s. Only with the Z8. Onlly few photos at the beginning of the import sequence has the embedded preview but all the others (the majority) do not. My last import of 780 photos, only 20 had the embedded preview. Very annoying!!

          Thanks, when I saw Jason's post 6 hours ago, I thought it was still in Discussions.

          @Rikk Flohr: Photography, you wrote on 2/15/22, "If someone can replicate these results, this post will be converted into a Bug Report without your having to do it."

           

          I provided a precise recipe on 8/31/22, including a sample Nikon Z 9 image:

          https://community.adobe.com/t5/lightroom-classic-bugs/p-z9-embedded-previews-are-missing-on-a-few-images-on-large-imports/idc-p/13172233#M39557 

           

          I've retested several times in LR 12.0.1 / Mac OS 12.6.1 and get identical results. What happens when you try the recipe?

          Issue: Embedded Previews not built when importing large numbers of Nikon Z9 NEFs

          When I'm shooting large numbers of images (sports/wildlife), my preference is to use embedded previews during the initial image review phase via the Library Module, as it speeds up image review immensly. With all other Nikon Z cameras, Lr honors embedded previews for all images during import. Since I got the Z9, however Lr only creates embedded previews for the first 30-75 images imported; the rest get standard previews. This issue has persisted since Jan 2022 and continues with the current version of Lr. This issue occurs regardless of the compression settings of my NEFs (lossless, high efficiency). I have spoken with other Z9 users who have replicated this issue.

           

          • Lightroom Classic Version Number: 12.0.1
          • OS Version Number: Mac OS Ventural 13.0.1

          Steps to reproduce:

          1. Import > 50 NEF images (any compression format)
          2. Choose "Embedded & Thumbnail" previews from the import dialog
          3. Ensure that in Preferences: General: "Replace embedded previews with standard previews during idle time" is unchecked.

           

          Expected result: All images show embedded previews after import

          Actual result: The first 30-75 images get embedded previews, but the remaining images do not; they get standard previews instead.

           

          I did a test import today of 109 Z9 NEF images; the first 74 were correctly given embedded previews while the remaining images did not.

          So far, I've tested:

           

          Mac 11.6.3

          Win 10 

           

          Canon 5DMKIV: Raw+JPEG in batches of 50 and 100 and cannot replicate the issue.  All images are badged as embedded previews and all previews are Camera Generated (I shoot Monochrome so I can instantly see an embedded vs LrC generated preview)

          Rikk-

          I believe this bug/issue is unique to the Nikon Z9. See JonKandel's post above. He replicated the issue with Z9 NEFs.

          None of my previous Nikon DSLR/Mirrorless cameras had this issue. I only started seeing it with the Z9.

          [This post contains formatting and embedded images that don't appear in email. View the post in your Web browser.]

           

          [Updated 12/9/22: Similar misbehavior occur swhen using Minimal instead of Embedded & Sidecar.]

           

          Here's a precise recipe for reproducing the problem on LR 11.5 / Mac OS 12.4:

           

          1. Download this sample Nikon Z 9 raw:

          https://www.dpreview.com/sample-galleries/2427213861/nikon-z9-production-sample-gallery/4584690814

           

          2. Place the file in a new folder and make 255 copies of it (in Finder or File Explorer, do select all, copy, paste 8 times).  

           

          3. Disable the options Preferences > Replace Embedded Previews With Standard Previews During Idle Time and > Select The Current/Previous Import Collection During Import.  Enable the option Preferences > Performance > Generate Previews In Parallel.  Disable Address Lookup and Face Detection.

           

          4. Import the folder from step 2, with the options Add and Build Previews: Embedded & Sidecar.

           

          5. When the import completes and the progress bar "Fetching Initial Previews" completes, observe that many (most?) of the thumbnails don't show the embedded-previews badge (see below).

           

          6. In Activity Monitor, observe the CPU usage of Lightroom Classic remains high for a minute or two. When it drops, scroll grid view by a whole pageful and observe that CPU usage again gets high.  When it drops, scroll again and observe CPU usage spike again.  This indicates that LR is generating standard-sized previews for the currently displayed thumbnails even though the option Replace Embedded Previews With Standard Previews During Idle Time is disabled.

           

           

          7. Select a couple dozen of the thumbnails missing the embedded-previews badge and do Library > Previews > Build Standard-Sized Previews.  Observe the message, "No standard previews were built", demonstrating that this isn't just a UI problem in grid view -- the standard previews were indeed built by Import.

           

          8. Repeat steps 1 - 7 but select Build Previews: Minimal instead. Observe similar incorrect symptoms, except that no preview badge appears at all.
