Welcome to Adobe Forums.
When the Video is imported in your PPT (Using Presenter 8), it came as a Shockwave Object.
You can change the the shape (Using the Circles on corner) or Right click and choose Properties.
True but is there a way for the video to maintain it's original sizes when you import?
Why does it resize my video when importing?
The big problem is that you need to figure out what the original size of the video was before Presenter changed the size. You can just try and guess by grabbing the edges and resizing it. The video looks terrible.
Let me check for an answer (Why does it resize my video when importing) with the concerned team.
I will let you know once I have an answer
