I do not see my all uploaded videoclips

Uploaded 9 clips overnight and all clips are ready to be keyworded.

Hi,
I am getting the same issue with footages; all pics are uploading just fine and all videos are "PROCESSING FAILED"!
They are in native codec and are accepted in Adobe Stock for example.
Rarely some are uploading just fine!?!

Anyone have got this issue and the solution by chance?

Thanks,
