The broadcast setting is specifically optimized for animation.  I'd try that render setting to start from, then if that doesn't fix the flicker enable user settings so as to be able to make some specific changes.  Under Advanced effects, in the general tab, look for jittering and expand it's drop-down menu.  For an animation, you want the reduced pulsation option.
