Aftereffect Render Engine Farm 2014 automation

Objective: To automative render engine 2014 to automatically render video formats (Quicktime, Mov, etc) Issue: 1. Currently, we are not able to get After Effect 2014 Render Engine to render files collected to output video formats. Need a way to automate it. 2. After Effect 2014 Render Engine is not able to render any files collected by After Effect 2015. Note: anyone who could help us solve the problems above will be rewarded. Thanks,
