A CD jack is about 4 3/4 by 5… so 4.75 X 300 dpi = 1425 and 5 x 300, = 1500… So you need an image that is around 1425 pixels x 1500…
If you export stills at the best settings, they will be wide enough, so it may work. Just make sure you set everything to best…
To save them as PDFs it’s best to use Photoshop, and make sure you use zip compression, not jpeg.
You can also use Apple Preview, but you may experience image deterioration, as it probably does jpeg compression.
