I work in Adobe After Effects only about once a month and don’t consider myself very knowledgeable with it yet and so whenever I learn something useful I like to share it with those who might share my pain.

I had imported a dozen vector graphics and was having them get larger and jump out.  But any time I scaled a graphic above 100%, the graphic became very soft and not in sharp focus, as if the graphic was not a vector graphic at all but a low resolution photo.

I googled my problem and discovered that there is a toggle next to each file in your composition that turns “continuously rasterize” on/off.  It looks like a little sun,  .  Once I did this for each image I had scaled above 100%, they all look perfectly sharp at any size just as vector graphics should.  Problem solved!
