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?

    Same issue with Lightroom Classic Version 15.5.1 on Windows 11 Pro.

    Disappointing - in the absence of a target resolution date for this SEV1 problem, I’m going to have to abandon ship for my project. Any suggestions for a product I could replace it with?

    No, I do not have any idea. The only possible action is to step back to 15.4.1

    I can reproduce the issue. After updating to version 15.5, the support for H.265/HEVC videos disappeared. The import window was not able to present the previews and later I have got a dialog listed all the failed H.265 videos. The import of H.264 videos still works. After downgrading to 15.4.1, I was able those videos. The updating to 15.5.1 the import of H.265 videos fails again. Another downgrade to 15.4.1, it works properly again.

    ​@Jorge31291960f9zv I opened a support ticket with Adobe, and they DO NOT ACKNOWLEDGE THAT THE PROBLEM IS WITH LIGHTROOM 15.5

     

    Ignore what Adobe customer support tells you -- they are often pretty random and not to be trusted. Reports in this section of the forum (Bug Reports) are in general the most reliable indication of the status of bugs.  The forum moderators ensure that this forum only contains bugs acknowledged / being investigated by Adobe. (I don’t work for Adobe.)

    El problema se produce al importar videos Códec: H.265 / HEVC. En mi caso realizados en cámara Sony. Veo los videos perfectamente con Windows Media Player con Windows 11. Tampoco tengo problema para trabajar con ellos con DaVinci Resolve. Si los guardas como H264 no tienes problemas en importarlos con Lightroom. Abrí una consulta con Adobe y NO RECONOCEN QUE EL PROBLEMA SEA DE LIGHTROOM 15.5

    ., dicen que el error es debido a los codecs de Windows 11. He actualizado codecs en Windows 11 y el problema persiste. Además no tiene sentido que me den esa respuesta cuando el reproductor genérico de Windows me abre los videos sin problema. No creo que la solución sea cambiar la configuración de mi cámara o pasar mis videos a H264 ni tampoco volver a una versión anterior de Lightroom. No sé además si eso afectaría a la edición de mis fotos anteriores. Entiendo que es un problema de ADOBE que no quiere reconocer y no se solucionará hasta que saquen una nueva versión.

    ​@adrianmarsh How do we know that Adobe has visibility into fixing this ?
    I see the forum message here… but I don’t see a bugid.

     

    The assigned internal tracking ids aren’t visible to mere mortals. However, the Adobe moderators are very good about curating the Bugs section to include only reports that they’ve acknowledged (usually by reproducing them) and are tracking internally. If a user posts in Bugs but Adobe isn’t able to reproduce the problem or doesn’t consider it a bug, the post will get moved into Questions within a day or two.

     

    This thread is 18 days old, and Adobe moderators have posted in the thread and merged other threads here, so it’s very likely it’s being tracked internally.

    Video is broken on LR 15.5, and the only known workaround is to roll back to LR 15.4:

    Fehler:
    Lightroom Classic - Import von Videodateien vom iPhone 14 nicht mehr möglich.

    Beschreibung:
    Die Videodateien (MOV) funktionieren problemlos am Windows PC.
    Selbst wenn ich die Videodateien manuell in den verwalteten Ordner von Lr CC ziehe und danach den Ordner synchronisieren will, kommt es zu einem Fehler. Die Daten werden in der Vorschau nicht angezeigt.
