the particles used in some bumpers from the 2009 academy award inspired me to do some test-renderings. in this example I used the simple C4D particle system with simple round shapes, camera DOF set and output as rpf (because of the preserved z-depth) with 16bit per pixel. the whole image sequence rendered with AE´s lens blur, some coloring & glowing and time remapping for speeding up at the initial start. one or more of the used effects didn´t support multiprocessor-rendering so the process of creating, rendering and tweaking took me nearly 4 hours.
