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.

    Okay... I did a test import. I had 109 images.

    If I only bring in 9 images at a time, I get embedded previews. I did this a few times in succession, and didn't have any issues.

    I then proceeded to import the remaining 73 images in the batch.

    The first 45 images had Embedded Previews, the remaining images did not; they got Standard Previews.

    Guess I'll submit a bug report.

      If someone can replicate these results, this post will be converted into a Bug Report without your having to do it. So far, I haven't been able to replicate this. 

       

      If you repeat your test import are the results identical?

      Hi Rikk-

      I'm using Lr 11.2, MacOS 12.1 and importing NEFs from a Nikon Z9. 

      I'll check out a few other things today. My normal import method is to "Add" photos that I've already copied to my computer using Photo Mechanic, but I've seen the same problem using direct card import from Lr.

      Could it be a glitch with reading Z9 NEFs? It happens with both lossless NEF and High Efficiency NEF.

      -Jason

      Do you apply a preset on import? If so, Lightroom will build have to a preview to show the effect of that preset.

      I use updated defaults. However, this problem never happened with Lr10.x

      I know Lr needs to build a preview to render presets/settings, but the whole point of Embedded Previews is to delay that operation until I go into the Develop Module.

      Embedded previews will often not permit viewing at 1:1. So it may be that zooming to 1:1 is what prompts Lightroom Classic to generate its own preview. 

       

      One alternative workflow may be to cull images within the import screen - thus reduce the numbers which go into the Catalog (or ever reach the computer at all, if this is a Copy import from camera card). For those not imported, LrC will never expend any effort making previews etc.

       

      You can use thumbnail or Loupe view in Import and this may be good enough for a first run through. Everything's extracted from the image file only. X or P to reject / accept, add Shift to step to the next image or else use arrow keys.
