Nobody can tell you anything without proper system information and things like version of AE, comp settings, render settings and so on. From a specific effect messing up to CoDec issues this could be anything.
I've tried rendering the same project with CS6 and CC 2015,
Using a mid 2014 15" MacBook Pro 2.8 GHz Intel Core i7, 16GB Ram, NVIDIA GeForce GT 750M 2048 MB
Using Curves, Radial Fast Blur, Bevel Alpha, Change to Color, and Fractal Noise... all inbuilt effects. Is there another way you need to see the info
What are your render settings and output module settings?
