I recently tried pulling still frames from a 4K video file in Lightroom. The process works since I can find the new original jpeg in the Finder window and the Video files shows up as a stack with the 2 in the corner. But I click on the number two, I do an Unstack etc. and the jpeg never shows in Lightroom. It was made since I find it in the Finder but nothing i do can make it show in Lightroom. I've even tried reimporting the new original jpeg back in to the Lightroom catalog. Any thoughts on this out there?
Yep, I tried this. Didn't work. Thanks for trying.
