I suggest that you remove all quotation marks and all space characters 
and all line feeds from the command line.
The following example is a little bit modified and working. But I did 
remove the timecode part because I didn't get that part working.

c://ffmpeg/ffmpeg -y -f lavfi -i testsrc2=size=hd720:duration=10 -f 
lavfi -i testsrc2=size=vga:duration=10 -filter_complex 
overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2,drawtext=fontsize=24:fontcolor=ffff00 at 0.5:fontfile='arial.ttf':text='Huntley':x=(w-text_w)/2:y=(h-text_h)-2 
-ac 2 -s 640x480 -preset veryfast out.mp4
