How do you expect to see the difference between interlaced and
progressive smtpebars?

I believe the tinterlace filter works fine but without horizontal
movement you will not be
able to see a difference.

Note that the following should simplify your command line:
$ ffmpeg -f lavfi -i filter1,filter2, ..., filtern
