Here are a few tips that can speed up render times.

- Make sure you are rendering at the correct dimensions. 1280×720 is perfectly fine for videos. 1920×1080 can increase render time dramatically.
 - Check your anti-aliasing in your Render settings. Min 1×1 and Max can be set 2×2; this is usually good. There is no need to use 4×4, which is the default and can increase render times significantly.
 - Shadows. Adjust what type of shadows you have on your lights. A Physically accurate setting will increase your render times when another shadow can be just as good.
 - Global illumination – can make your renders look really professional, but will also increase render times. Make sure you need it.
 - When rendering, make sure you don’t have all your quality settings on High (Anti-aliasing, GI, AO, Reflections) when previewing.
 - Go to Render Menu – Make Preview for just previewing renders.
 - Make sure any Reflective on Transparent materials are needed. Reflections will dramatically increase render times.
 - Do you have an old computer lying around? You could use team render to use the power of all your computers to give you a bump in render speed. Team render is free with any purchase of Cinema 4D and easy to set up.
