How to render without a bg?

I made an rotating object and I want to upload it to video hive ,I suppose I should submit it to “Motion Graphics” >>> “Elements” , no? So I want to know how should I render my object so that it wont have a bg and be accepted by the reviewer ?

Render with Alpha Channel.

You should render it out as A “MOV” format .. in the render queue settings >>> Output module >>> format “Quick time” and Format options… “PNG” and channels “RGB+alpha” Best wiches
