Lightroom Classic: Videos don't play and don't import

Resetting your preference file would be a good next step. 

Hi Rikk, that did not work. I encounter this error on two machines I use (one at home and one at the office.) They both have the same issue with video-files.

It's been six months since this problem appeared, and no solution yet...I've been so disappointed by Adobe's help service, that I've gone to Capture One, where I have no problem.

@Fred van Os

If a preference file did not solve it the next step would be to conduct a clean reinstall of Lightroom Classic: 

Lightroom Clean Install Procedure with the current version:

• Close Lightroom
• Restart the computer
• Use the Adobe Creative Cloud App to uninstall Lightroom Classic
• Restart the computer
• Install Lightroom Classic via the Creative Cloud App without launching any other programs.
• Restart the computer
• Launch Lightroom
• Wait 5 minutes

Hi Rikk, Thanks for answering. But unfortunately it did not work. Still same error.

If you create a new OS-level user account for test purposes, does the video work when logging into the new account?

Hi Rikk, I will give it a try, although I have my doubts, but I'll let you know. I work with 2 different ligtrooms catalogs on different macs (but same version of lightroom). One is at home and one on my work. Both have the same issues with video.

Hi Rikk, I have don what you suggested. Created new user and created a new Lightroom project. Same results. Video's will not be imported.

Have you shared a video with me yet for testing? I don't see one in my records. 

Hi Rikk. Here a  wetransfer link. Containing a video witch is not recognised anymore by lichtroom. https://we.tl/t-YS7Zq3NiLU

I downloaded the video. 
Lightroom 9.2 - Mac OS 10.14.6
Video Imports
Video Plays
Video Exports

Hi Rikk, Hmm. nice for you.  But at my place in doesn't. I am kind of stuck on it. I have tried on a iMac Pro this last action. New user, new library. Nothing works. Specs 16 GB Radeon Pro video. Internal memory, 64 GB.
Error message from lightroom: An unknown error has occurred while reading the video file. Connecting to Dynamic Link server failed. (2)
It is a bit frustration, since I use lightroom a lot for catalogue of photo and video material.

At this point, I would recommend looking at any common software you might be running that is interfering with the Dynamic Link Media Server operations.  Virus detectors, firewalls, corporate nannyware, etc are all places to look. Since you see it on two different machines I would concentrate on commonalities between the systems.  I've since tested your file on Catalina and Windows 10 as well and do not have any issues on my end. 

Hi Rikk, Again thanks for answering. There are no firewalls, virus detectors, corporate nanayware, or so. Not on my company mac or at home.
I have deleted all preference files, of all programs. Since is a pain in the *** ro reinstall everything (I have a lot of plugins for priemere and after effects with need to be deactivated first).
So, again Removed  adobe lightroom software. Reboot the mac. So no files of adobe lightroom remaining. Reinstalled lightroom, launched it. Same error. No import of video or playback of video.
I am running on Mojave (not Catalina). Since this errors occurs for me in version 9, no new software is being installed on my system since it occurred, apart from updates. Is their a list of programs using Dynamic Link? 

At this point the only stone I have left unturned is a complete Adobe Clean.  This involves using the Adobe Cleaner Tool to completely wipe Adobe Products and all residual files from the system. It is a radical step, agreed, but it is the only place I have left to go - save the operating system. 

Understanding you have many Adobe Products this is not easy nor quick. 

If you do decide to use the cleaner tool, I would recommend running the process, then installing Lightroom first and testing it to see if you still have the issue with this video file.

Hi Rikk, This will take some time.
 But I am working on it. I am trying to do a clean install od the OS and then I will only install lightroom on it. But it will take some time to do so. Have to keep on working on the same system.

Hello Forum and Rikk, I have installed a new clean mac OS version. 10.14.6. ona saperate SSD, removed the old system SSD. I Only installed Adobe cloud and Lightroom. Nothing else, no other programs. Created a new catalog.  Imported photos but again no video's.

I really do hope Adobe pics this up. and put this on a high priority list. Since more people are having this problem.

Hello? Since my last post I have heard nothing. I have put a lot of time in this issue. Come on Adobe, give some feedback. 

How can I send you a video?

Hi,

You can send me the videos which are not working via DropBox, OneDrive or Google Drive. Any file sharing app would be fine.

The issue is happening with all your videos or only some of them. Could you please confirm this ? This would help us know the issue better.

Hi, it is happening with all videos. Can not play videos that have been in library for years, can not import any new videos.

Carl

I just tried a test.  I imported a video into Lightroom mobile and I could play it back in LRC (after synching).  However, if I try to import that same video into any location (hard drive, external drive, desktop), it would not play it in LRC.

So, it does work from an LR Mobile-imported video, not in a regular imported video.

Does that make sense?

This is ANY video I've made, and for this test I just created one on my iPhone 11Pro.

Hello,

See my threat with Rikk on page 2 of this forum-treat. I have the same problems with video. I have tried many options to fix it. Even did a a complete clean install. Nothing seams to work. Atfter this 'test' is became quitein this forum.As I do both video and photo,  Lightroom is great for managing both video and photo's. I really hope Adobe put this on the priority list to fix.
