Problem visioning a video in Cubase 9

Hello everyone !

I have a problem visioning videos (AppleProRes) in Cubase 9.
i see only 30 % of the image. the middle. missing the full size image of my videos.
I put the correct 25 frame per seconds in “Project setup”.
if someone knows about this, it is very welcome !
thank you !


What video codec do you use? What format? Where was the video file created?

I created the video myself. from Final cut pro X.
