Te copio del foro de Yafray:
to render this animation with Yafray, choose a directory in the output panel of the render settings of Blender.
Bak in Yafray, chek your render settings and press the render animation button. (you can cancel the animation with Esc now).
Yafray renders animations in image sequences (in (*.png) or.exr). You can use Blender video sequence editor todo make a video from this image sequence.
