For Maya software rendering only.
The settings you use for rendering images as fields may depend on the hardware or software settings you are using with the images, and how they interlace fields together (for example, the interlace utility, compositing software, or frame buffer device). Before you render an animation as fields, perform a test render and use the test rendered images through your entire post-production process (see Batch render a still or animation and Test render a low-res animation).
Even though Maya automatically sets these options depending on whether the Resolution is NTSC or PAL, if you encounter problems in the animation where objects vibrate up and down, change the Zeroth Scanline setting and test render the animation again. If this does not solve the problem, or if objects in the animation vibrate left to right, try different combinations of Field Dominance and Zeroth Scanline, and test render the animation until the problem is solved.
