Can you be more specific?
Since we are in the PrPro forum, let's concentrate on it.
What are the settings of the Sequence, in the Project, into which you are Importing that material?
How is it the "wrong size?"
Does your Sequence match the footage from the 7D MK II?
Now, you can Import the Clips into the Project, and then drag one to the New Icon in the Project Panel, and PrPro will create a matching Sequence.
