I updated to LrC 15.5 a few hours ago. Since then LrC has problems with video files. The first problem I noticed was that when I tried to synchronize a folder that had two new video files. After a couple of minutes I got the error message “An unknown error occurred while reading the video file. (2)”. I had just completed those files with DaVinci Resolve so I went back and produced the same files again to check if DR had made an error. When I tried again with the new files but got the same errors. I was able to play both videos without any issue using VLC Media Player, so they seem to be OK. I then shutdown LrC and did a backup including optimizing the catalog, and then restarted it to see if that made any difference, but same error. Then I started looking at other videos that were already in LrC and found that when browsing them in the Library module, most of them pop up a message “There was an error working with the video”. They will not play in LrC but work fine with VLC Media Player.

Prior to upgrading to 15.5 I did not experience any of these errors. Is anyone else seeing these problems?

Now I am getting another message, “Enable rendering of HDR content in Library views". I see that such a message was first added in v14.0 such that if HDR photos were found the message would appear. I have never seen the message until today after upgrading to v15.5, and so far as I know I have no HDR photos. This is not attached to any particular photos but is present as I move around in the Library module. I did not click “Enable” I just clicked the X, and it disappeared. At least for now.

I am still unable to import video files, and I still am unable to view most video files that have already been imported.

Given that Rikk is adding likes to posts that imply there is no issue with 15.5, I decided Adobe is not going to take this seriously, so I deleted version 15.5 and reloaded version 15.4. Everything is back to normal. I am again able to import video files, and I can browse and play videos in the Library module. Unfortunately, I don’t have access to the mask adjustments introduced in 15.5.

Please post a copy of your LrC System Info. This can be obtained from the LrC Help > System Info menu item. Use the Copy button at top right of the System Info dialog to capture the info.

Since the threading in this forum can be bit of a mess, mention in first line of your post that you’ve downgraded to 15.4, which works fine.

After latest update "There was an error working with the video" message appears for all of my GoPro videos leaded earlier this year. Videos from other cameras still process just fine.

I do not have any issues with videos in Lightroom Classic 15.5 on my Mac.

Have you tried resetting the LrC Preference file? This is a useful self-check that can easily be made when odd behaviour occurs, especially after the application has been upgraded. You can use Method 1 as shown in below linked help document:

Tried that, no change.

It’s amazing that after so many years this is still a bug in Lightroom, and is recommended for any unusual behavior. Sometimes it works, but, alas, not in this case.
