Since a few month i upload also video to Shutterstock
My latest 4 videos were rejected for
Focus: Subject is not in focus or focus is too soft, inconsistent, or rack focus is not executed well.

If i played the video, the video looked sharp.
I don't understand what's wrong

What they mean with focus is too soft and rack focus is not executed well?
How can i in the future avoid focus rejections?
My images were the last few years never rejected for focus.

How can i in the future avoid focus rejections?

I remember i had some hard time and rejections last year when i tried to upload
a. Focus pulling between two subjects or just foreground / background
b. Clips with kind of fast motion that created motion blur.
c. Stabilized clips (again blurred in places)
d. Non razor sharp clips as long as i only had the manual focus option.
