PNGs export blurry and aliased

My characters appear beautiful and crisp in Illustrator and character animator on screen, however whenever I export them as a PNG sequence from CA the lines soften and become aliased resulting in a soft fuzzy animation. Have tried a variety of export settings with no luck. There is no scaling of characters - I've created them at 100% to test this. The issue is not something in AI but a bug in the program of CA.

Attached are two PNGs of the same character at 100% scale in both programs. AI exports beautifully, CA is aliased and blurry.

If anyone can fix this for me that would be AMAZING.

Exported at 100% from AI:

Exported at 100% from CA:  1080p scene. Both characters are same size.

Running OSX Sierra 10.12.6 if that helps.

Any way to fix this?

Thanks!
