The documentation shows that you can use other parameters with x or y such as input video height and width and text width and height. To place the text on the bottom one method is y=main_h-text_h. If you want a little padding on the bottom you can use y=main_h-(text_h*2) To center it horizontally use x=(main_w/2-text_w/2).
