You are not connecting the filters to each other correctly. (I actually
thought that you would lose the yadif, but still get the overlay.
That's why you need to provide us with the complete, uncut console
output!)

You need to connect the output of yadif to one of the inputs of
overlay:

  -filter_complex "[0:0]yadif=0:-1:0[base]; [base][0:5]overlay[v]" -map "[v]"
