P: Videos do not play or import macOS High Sierra

Yes I can import those and all videos with Lightroom 5 and 6 but not Lightroom 7

Thank you for Reporting this issue. We are currently investigating this issue.

I am able to import those videos on same machine configuration.

I have exactly the same problem

As I have pointed out it makes no difference what the video or format is.   W/hen Lightroom is not working none of them work.   Here is a dropbox link of a variety of videos.   Again all of these videos work routinely in Lightroom 5, Quicktime on my make and using the VLC player.

Hi Paul,

Can you please share a sample file which will help us to identify the root cause? you can PM @ kanagraw@adobe.com
Are you able to import a new video(apart from reimporting) ?

Thank you for the follow up.   The issue is not related to a specific video or format.   All videos are not working.  I have created a catalog in Lightroom 5 and imported all my videos to that catalog.    They all work fine.   As a test I exported all the videos from lightroom 5 to a separate folder in H264 format.   None of these videos will open in Lightrom Classicc CC.   I have about 300 short videos taken with a varity of cameras, Sony Alpha, Lumix, Canon, iphone etc.    All are behaving the same.

This problem startee either with upgrade to Lightroom Classic CC or the upgrade to High Sierra.   I noted it when trying to reorganize and remimport photos    At first I thought it was just the photos I was moving.   Upon further analysis I found it was all photos.

I have found that sometimes when I close Lightroom and reopen it wil appear to work and may work on 1 or two videos then it stops.  Sometimes I will get the message "The Video player has stopped working.  Please relauch?   Other times it just hangs on on the video or I get a black dot in the upper right of the thumbnail with the error message "Lightroom has encountered problems reading this video."

I have tried every tip in the forums and on line with no resultes.   I have uninstalled and reinstalled Lightroom a number of rtimes.

Current configurartion:

Lightroom Classic CC 7.0.1
Macbook Pro 2017
16GB Ram
1 TB SSD
OSX High Sierra 10.13.1
