The squished look has to do with square and non-square pixels. When creating images in Adobe Photoshop® and importing them into GenCG, the visual canvas has square pixels. When you take the graphics you generated to air, it becomes non-square pixels as it turns to video footage. The conversion between the two squishes your images slightly. Please go through the following steps in Adobe Photoshop® to correct the issue.
In Adobe Photoshop® after creating the images, go to [Image] > [Image Size].
Under [Pixel Dimension], change [Pixels] to [Percent].
Width should be 118.29% and Height should be 108.95%.
