Premiere Elements 10 on what computer operating system? What video card/graphics card does your computer use? If NVIDIA GeForce, then we need to talk about display and other issues related specifically to Premiere Elements 10/NVIDIA GeForce.
But, for now putting that aside.....
Each clip on the Premiere Elements 10 Timeline has a Properties Palette which contains a Motion Panel. The Motion Panel expanded has settings for the clip's Position and Scale. among other things.
Position as two values ... (___) (___) first for right to left and left to right...second for up to down or down to up.
Have you gone into the Properties Palette of the 2nd clip to set its Position and Scale values to match that of the first clip?
Have you been there and done that?
