P: LrC 15.5 Video Files Issues (Windows)

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?

Issue Title: Lightroom Classic v15.5.1: `.mov` import failure and "There was an error working with the video" playback error on Windows 11 (AMD Ryzen 5600G)

System & Hardware Setup:

OS: Windows 11 (fully updated)
Lightroom Classic Version: 15.5.1
Processor / GPU: AMD Ryzen 5 5600G with integrated Radeon Vega 7 Graphics (No dedicated GPU installed)
Media Details: .mov files fail both on import and playback within Lightroom, but play back perfectly fine using native Windows media players and VLC. Also previously imported .mov files, which worked previously in Lightroom Classic is now failing to play.

Description of the Problem: Since updating to Lightroom Classic v15.5.x, I am unable to import certain .mov files. For previously imported .mov files, Lightroom throws the error message: "There was an error working with the video".

Because these exact files play without any issue in Windows Media Player and external players, the operating system and hardware decoders are fully capable of reading them. This points directly to a regression or compatibility bug in Lightroom Classic’s internal video rendering/import pipeline on Windows 11 systems running on integrated graphics.

Troubleshooting Steps Already Attempted (All Failed to Resolve the Issue):

Codec Installation: Installed official HEIF/HEVC Video Extensions from the Microsoft Store and restarted the PC.
GPU / Performance Settings: Verified and tested with Graphics Processor disabled, as well as forcing Lightroom Classic via Windows Graphics Settings to run under the "High Performance" profile utilizing the AMD Vega integrated graphics.
Driver Updates: Clean-installed the absolute newest AMD Software: Adrenalin Edition driver for the Ryzen 5 5600G.
Cache Maintenance: Cleared both the Camera Raw Cache and the Video Cache within Lightroom preferences.
Preferences Reset: Performed a complete preferences reset (Shift + Alt launch) to clear out any corrupted post-update configuration files.

Where can I sign up for a notification confirming that the no video uploads into Lrc 15.5 issue is fixed and it's safe to download a new version (switched to manual rather than auto upgrades for now)?

When can I get a credit towards my Adobe bill for this regression issue? This much pain and suffering earned some money regressing back to me.

Spent hours, bought a codec on Windows store and couldn’t import videos since weeks.
Now finally asked KI und it told me after again hours it was a known bug.
Went back to 15.4.1 and it works again.
Why does it take Adobe so long to fix this, already disappointed that lightroom is slow and can’t do anything with videos, now this, does Adobe want me to quit my subscription?

EXACTLY my experience! (except):

-spent DAYS, not hours.

-bought the Microsoft Codec (again!)

-learned (again) you don’t need to buy the Codec

-asked AI multiple times and got the same answer about clearing the cache, and other nonsense which didn’t work.

-finally got the good answer, downgraded to 15.4.1 as recommended, which worked, alowing importing of videos into Lrc again, showing thumbnails, and allowing them to play as prevously.

-had to fix a bunch of folders on different drives which were used after the upgrade

-finally returned to normal functionality but keep getting the prompt to upgrade Lightroom Classic so found this page after wondering how I will know it’s safe to upgrade Lightroom again

-wondered the exact same thing: does Adobe WANT me to quit my subscription?!

I contacted support tonight on this. A nice friendly person called Roshan said they would escalate this up to the next tiers and that someone would come and update us here (or me by email).

I’d like to add to this (probably another form of the same bug). For HEVC videos taken on iPhone 16 Pro, then imported to LR Mobile on my device, these sync just fine to LR in the cloud, and I can see them on LR Web and my other mobile devices (i.e. iPad with LR Mobile).

However, when LR Classic 15.5.1 on my Windows 11 machine attempts to sync the videos, they result it an Error. I’ve even removed these videos from cloud and reimported them from the device. All the videos have this error. Other photos are importing fine.

I can also confirm that LR is unable to work with or even display thumbnails for videos that were previously imported:

Same issue here with 15.5 AND 15.5.1 in LR CC on Windows! I can’t import new HEVC videos or even play already imported HEVC videos.

Issue still present in 15.6! Come on Adobe!

Official workaround is not usable to me because 15.4.1 has another bug which prevents AI-denoised images from being opened as layers in Photoshop 😡
