P: Videos do not play or import macOS High Sierra

Previous issue was solved and is years old. Creating new thread to monitor

Please reference the new conversation here: Lightroom Classic: (9.1) Videos have exclamation marks and adjustments are not po...

Feb 2020, Lightroom Classic 9.1, Mac OS Catalina (all updated) and this issue has still not been resolved. I have massive amounts of videos with exclamation marks and "Lightroom will not be able to make adjustments". Pathetic.

Hi All,

Can you please try to import videos in the latest Lr Classic 8.0 version and let us know if you are facing any issues?

I had the same problem. In Lightroom 5 it worked. Trying Lightroom CC suddenly problems with a lot of videos, they dont get imported at all and i get the above mentioned error message (btw Im on 10.12 Sierra)

After installing the Prelude and the Media Encoder it worked and Lightroom started importing my videos correctly (When installing Prelude, it automatically installs a program called Media Encoder CC saying: "Schnelle Ausgabe von Video Dateien für nahezu jedes Bildschirmformat")
I did not deinstall anything, any of my old Lightrooms, for this. But the problem is that you cant do this if you only have the Photo Bundle.

Thanks for the confirmation, Paul. I will touch bases with engineering again. 

I have upgraded to 7.3.1.   Al indications are that the problem still exists.     I do not that the import dialog process is MUCH SLOWER than previously.

If you've performed the steps and ended up at 7.3 and still have the issue, I am asking to do the update to 7.3.1 (without the uninstall/cleaner steps) and see if the issue is still present. 

Thanks for your help!

Some I have already uninstalled all the app, run the cleaner and installed 7.3 are you suggesting I do it again or just update to 7.3.1. Nothing in the update notes says anything about dealing with video or performance.

Lightroom Classic CC 7.3.1 was released earlier today. Can anyone confirm they are still seeing the issue after installing 7.3.1 and having performed the steps outlined in my post 4 days ago?

Thanks, I will report that to engineering.
