Is there a way to adjust the position of an imported .cpvc file?

I've been trying out different ways of adding a video into a regular (.cptx) project. The end goal is to get a video into a .cptx file while ensuring that there is white space to, let's say, the right of the video so that the video can "play" on the left-hand side of the frame, while having a static caption box/script of the video's audio on the right-hand side of the same frame. 

I've tried adding a published video to my .cptx file, but not only is the video quality poor, but when I adjust the video size (even if the video was recorded in a stage/area much smaller than the .cptx project), the video quality gets all wonky. (Even manually adjusting the width and height doesn't seem to help much - maybe it's because I'm constraining the proportions.) 

Adding a .cpvc file directly into my .cptx file helps tremendously with the video quality, but the issue now is how to "move" the video's position so that there is more white space on one side of the frame vs the other. Can this be done? I've tried experimenting with different sized capture areas for the video demo, and even with a capture area of 800x600, inserting that .cpvc file into a .cptx file that is set at 1024x627 still doesn't work. I've also tried to adjust the Grid Size of the different video demos, but that makes no obvious changes.
