Try manually deleting the video cache -- that helped another person: Videos don't play and don't import | Photoshop Family Customer Community

That did not work. I deleted the video cache from the Preferences Panel. Lightroom Classic CC hung dead. Then I forced quit and found the video cache files in the Finder and deleted by hand. Restarted Lightroom, video still not working.

Working off another lead found by Google-Fu I tried to delete Quicktime. One can't delete it in High Sierra. Undeterred, I deleted all the Quicktime support files (courtesy of App cleaner), poured myself a Scotch, and reinstalled High Sierra from the App Store.

Seems to be working now!

The issue has been recurring after moving a lot of video files between folders. (I am in the process of freeing my clips from iMovie jail and moving them into Lightroom to simply my life when trying to select images for a slideshow) .

What seems to fix it now is to restart with fresh preferences file. I guess the long path I took also got me a fresh preference file!

Hopefully, someone in Adobe will notice this and check the interaction between a new preference file and video. Perhaps it clears some cache somewhere.

(Mac OSX El Capitan, 10.11.6)

After hours of searching these forums and the web to determine why my MOV and MP4 files no longer worked after  I upgraded from Lightroom 4 to Lightroom Classic CC, I found it was due to a bug with Quicktime after an El Capitan upgrade, and this cured my problem:

QuickTime X doesn't work after El Capitan… - Apple Community

----------------------------------

(excerpted from above Link-- As RJTUK recommended:

To delete QuickTime preferences follow the steps below:

1. Make sure that Quicktime is not running.

2. From your desktop select the Go menu while holding the Option key on your keyboard and select Library open the Preferences folder and drag the following files to your trash:

com.apple.quicktime.plugin.preferences.plist

com.apple.QuickTimePlayerX.LSSharedFileList.plist

Restart your Mac and try again.

----------------------

All my MOV and MP4 files came alive again after doing this.  Hope it works for you!

I suppose I have a similar question.

Video thumbnails won't play from within Lightroom 6 but they will play in Apple's File Manager.

Something dodgy's going on I suppose.

I was playing time-lapse videos captured with my iPhone X in LR CC (iPad) just fine, but got the same error when I tried to bring them into Lr Classic CC. I used Compressor (Final Cut) to save copies of the videos and then they imported and played just fine.

This sounds like a different problem than the original poster's.  How did you "try to bring them into Lr Classic", and what error message did you get?

If you tried to use Import and got this message:

then almost certainly the problem is that the videos were recorded by iOS in the "new" HEVC format, which isn't yet supported by LR Classic.  Adobe has officially promised support "soon": Lightroom Classic and CC: Please support HEVC (H.265) video support | Photoshop Family Customer Comm...

You can change the iOS default to be MP4 by checking the iOS option Settings > Camera > Formats > Most Compatible.  The subsequent quality of the videos will be about the same but their file size will be about twice as big as HEVC.

I have the same problem. Literally hundreds of videos just stopped working. Can't import them any more either. Previously, all of this stuff worked. Tried all of the above stuff and it didn't work.

It would be nice if there were clear instructions on how to remove and reinstall LR Classic without losing all the libraries and add-ons...becuase last time this happened, I did a complete R*R of everything..and it all worked for about 2 months. Then, one day, it just stopped working again.

Hi,

Thanks for reporting the issue. Do you mind sharing the videos which you are unable to import or play in Lightroom? We would try to reproduce the issue in-house and let you know.

There's literally 100s of them...I have a terrabyte plus of photos and videos in my library. They are one of a few types of files:

1) They come off a Canon DSLR

2) They come off an iPhone

3) They come off a GoPro

 

I've been using LR classic for years with these same file types. Everything has always worked. Now, suddenly, twice in the last 3 months, you can no longer play them and you can no longer import ANY video.

Hi,

 

1. Are you able to import or play at least some formats/videos or nothing at all? 

2. When was it last (mention Lr version) where you could play the videos without any issues?

3. Please follow the debug steps in the following link: https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-video-issues.html

 

If your issue is still not resolved then could you please share us a sample each from different Devices if possible. (over Dropbox/ Drive or any other link)

Regards, Sumeet

Hi,

 

I am unable to import ANY video of any sort. I'll try the debug steps. Your troubleshooting steps are not in the right direction if you are asking me for video clips. It happens with ANY video.

Hi,

 

Thanks for the information. As I see, you are not able to import any video, please follow the debug steps mentioned in https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-video-issues.html

These steps are to help you import/play videos that used to play earlier but no longer play now.

Let us know if that helps. Else we can try to debug in a different direction.

Regards, Sumeet

Hi,

 

Sorry to hear that it didn't work for you. It means you have already done the following :

  • Install any updates available for your OS.
  • Install any updates available for your GPU driver.
  • Cleared cache.
  • Made sure you have enough disk space available.
  • Deleted the Video Cache files
  • Tried killing dynamiclinkmediaserver and dynamiclinkmediamanager if they stay even after closing Lightroom.

Please share your system details with us. Could you please post your "System Info" [LR -> Help -> System Info]. Also let us know if you have Quicktime or VLC Media player installed in your system.

Regards, Sumeet
