Experts Users: Arnold Renderer for Cinema 4D - What final Render settings are you using for your 3d Animations to Broadcast/Web output?

I had been using mainly physical Rendering engine for sometime and VRay to some degree. However, feeling the urge to try out 'Arnold Render' for my future projects.

Wanted to know, your settings for final delivery? Octane Render seems to be amazing too curious to know your opinion on these products. Thanks/

Also, what time format are you working with out of C4D i.e.: 

.PNG

.TIFFs

.EXR

OR

.DPX (my Favourite these days).

Happy New year folks!
