5DIII Raw video doesn't want to write

[lesapou]

Hello !

I am using a 5DIII and wanted to record in raw 1920x1080, all the right setting are done, but it still can't record more than 2-3scd.

And when i test the card it say writing at 20.1Mb/s, i can't found anywhere how to fix the pb.. it seem like the Camera doesn't want to write properly on the CF (like it was a SD card)

Does someone know how to fix the problème ?

Thanks a lot !
