Two ways:
1.) go to the render menu or icon and select preview…that will give you low resoultion preview renders
2.) go to the render settings and set the number of frames, size… you want AA quality… then in the save section set the file name and select the format… close out of the settings and click render to picture viewer.
hope this helps…
