How do I shrink the size of the sub-title box

Hello,

My name is Jacob. I love your product.

I have three questions.

1) How do I shrink the size of the sub-title box? Not the text, the box it self.

2) If I remove the sub-title box (closed caption), by clicking the eye on the "bottom bar design" will that remove the box and increase the viewing size of the video? Sometime, I only want the title box and not the sub-title box at the bottom.

3) Similar to the first question, is there a way to resize the top bar with the titles are contained? I find that they are pretty large, relative to to my video.

This video illustrates things pretty well. https://adilo.bigcommand.com/watch/PBzch95C
