Hi,

I try to rename file from ZV1. So i have a file call C0121.mp4 when I try to rename it with exiftool like this
E:\0000-01-01 - Modèle Première\0000-01-01 - Modèle Première\02 SOURCES\Vidéos>exiftool "-filename<$FileCreateDate - %f - ${model;}.%e" -api QuickTimeUTC  -d "%Y-%m-%d %H-%M-%S" .
Warning: [minor] The ExtractEmbedded option may find more tags in the media data - ./C0121.MP4
Warning: No writable tags set from ./C0121.MP4
    1 directories scanned
    0 image files updated
    1 image files unchanged

Whereas File CreateDate seems to be create
E:\0000-01-01 - Modèle Première\0000-01-01 - Modèle Première\02 SOURCES\Vidéos>exiftool -time:all -s C0441.mp4
FileModifyDate                  : 2021:07:10 13:26:24+02:00

FileCreateDate                  : 2021:07:14 12:55:09+02:00

What is the result of this command?
exiftool -Model ./C0121.MP4

Thank's for your help. The result is :

That's why you get the "No writable tags set" warninng.  There is no Model tag in that file.  You'll have to remove ${model;} from your command.

Thank's for your perfect quick help !
