Title says it all. Movie file thumbnails from iPhone and iPhone apps are not appearing in Bridge 2019. I went back and tried 2018, and there they were. Any ideas?
Could you try the steps below and let us know if it helps?
Launch Bridge -> open Preferences Dialog -> Advanced Tab -> Turn on "Use Software Rendering" -> Restart Bridge -> Now purge cache for above shown files.
It is showing the thumbnails now without doing what you said, but now I've come back to this for a specific reason.
I was trying to transfer photos and movie files from my iphone to my Windows machine just with copy and paste. I got to a point where it would give me an error that the device was unreachable. So I tried the solution given here:"Device is unreachable" Error message whe… - Apple Community
It allowed me to go ahead and transfer the content, but the images are now in .heic format which I have to convert to .jpg, and the movie files, while they still are are .MOV files, are not showing a thumb. They play ok though.
I tried the software thing and it didn't change the issue.
This is still an issue.
I too have this issue... I've tried the above steps, as well as turning on Sotware Rendering.
I am using the latest release of Bridge (2020) running on a 2013 15-inch Retina MacBook Pro - macOS Mojave (10.14.6)
This is very frustrating as it has me looking to other software for something that should work as part of my Creative Cloud subscription.
This is STILL an issue.
All I needed to do was tick Generate "Monitor-Size Previews". I left "Use Software Rendering" unticked and that worked for me.
