Bonjour

Depuis que j’ai déplacé ma base de données photos et vidéos de mon serveur NAS Synology vers un disque externe, Lightroom (version 11.3.1) ne veut plus importer mes fichiers vidéos Mp4 ni lire les vidéos déjà présentes sur la base de données. Je précise que l’importation de photos quelles qu’elles soient (raw, jpeg, Tiff, Png etc) se passe très bien.

Je suis sur Mac OS Catalina V 10.15.7. 

Toutes mes photos et vidéos sont sur un disque externe G Raid de 4 TERA (2 x 2 Tera Raid 0) Formatage Mac OS étendu (journalisé)

Lorsque j’essaie d’importer des vidéos j’ai un message qui dit « Aperçu non disponible pour ce fichier » (voir capture d’écran 1) et si j’essaie de l’importer quand même j’ai le message (voir capture d’écran 2) « Lightroom ne peut pas lire le fichier vidéo. Le fichier contient un type de compression non pris en charge »

Si j’importe la même vidéo stockée sur le disque interne de mon Mac ou sur mon NAS Synology, tout se passe normalement et je peux les visualiser dans Lightroom.

J’ai essayé d’importer des MP4 venant d’autres disques externes et j’ai le même problème.

J’ai essayé tous les formatages de disque possible avec l’utilitaire de disque mais rien n’y fait.

Est-ce une problème de disque ?

Serait-ce le déplacement de la base de données photos qui pose problème ?

Si quelqu’un pouvait éclairer ma lanterne et trouver la cause de mes problèmes, je lui serait infiniment reconnaissant.

Merci d’avance

To clarify... are you having a problem with all MP4 videos or only new videos that you try to import? Are you importing from a camera card or have you copied the files to the new external drive. If the videos were already in your catalog why are you importing them again? If I read this correctly you've relocated your files from your Synology to another external drive. If you've updated the folder location within the Library module the files do not need to be reimported. More information may be helpful to better understand the problem. Also is this only with MP4s - do other video file types import without a problem?

Thank you for your reply

The problem is with all MP4 videos.
I import from camera to external drive via EOS Utility and then import them into Lightroom from external drive. If I import directly from Lightroom, the problem remains the same.
I'm not re-importing the videos, I just moved all the photos and videos to a new external drive.
Other types of video files have the same problem.
Videos that I place on my internal hard drive and import into Lightroom are viewable without any issues.
I hope I was clear enough in my answers.
Thank you in advance for your help

Do you have another external drive that you can test? This is to eliminate or identify whether it is this particular drive. If this disk did not have permissions for Lightroom Classic to have Full Disk Access you would have more problems than not being able to view videos.

 

You've ruled out already that there isn't a problem if the video files are on your synology or your local drive. If it is just this drive you may want to try a disk repair in disk utilities - if you've run a repair please confirm that. 

 

Do you have any custom user presets? Have you tried to reset your preferences? Hold down the Option key upon restart and Reset preferences - keep in mind that you may need to reload your custom user preferences.

Hello

I tested with several external drives. the problem is the same.
Disk Utility reported no errors on the G-RAID disk in question.
When you suggest resetting my preferences, you mean Lightroom or my Mac?
when I hold down the Option key when starting LR I get the screen you can see in the attached photo (Screenshot 2022-05-17 at 06.16.08)
Have a nice day and thanks again for your help.

I was referrering to resetting preferences in Lightroom Classic. Thanks for the screen shot... it tells a story! You have kept all of your catalogs and they're taking up storage space unnecessarily - probably a good idea to remove them. It also gave me an idea for you to try. Can you create a brand  new catalog and import a video from each source (card, Synology and local drive) - a new video and see if it works? I'm wondering if the catalog you are using has a problem. Also wondering if you have tried using a backup version of this catalog?
