Thanks for the two clips, no zoom and zoom.
What is producing the zooms - Premiere Elements Pan and Zoom Tool or just using the project's Scale property to zoom in on the more distance scenes?
Scaling....selecting the clip and then Applied Effects/Applied Effects Palette/Motion Panel expanded's Scale slider
or scaling in the Edit area monitor by clicking the image in the monitor, getting the image's bounding box with handles, and then dragging on a bounding box
handle for the scaling?
I can envision lost quality depending on how much you needed to zoom in. If I have interpreted this correct, you might explore fx Effects/Blur & Sharpen/Sharpen
just a little to see if that improves the image clarity on the zoomed in content.
I will think about this some more.
