Answers.Text: Thank you for the quick response! Now looking at it it seems so clear but you have no idea how many different orderings of the first command that I tried to no avail!

  The basic form will be
  
  ```
  ffmpeg -i video.mp4 -i image.png -filter_complex "[1:v]scale=320:-1[top];[top][0:v]vstack" output.mp4
  
  ```
  
  A label of the form `1:v`, equivalent to `1:v:0` within filters, is a stream specifier - it means use the first video stream of the 2nd input. `0:v` refers to the first video stream of the first input.
  
  The `bottom` in your command and `top` in mine are arbitrary labels assigned to the result of the scale filter.
  
  Then that resulting stream is fed first to the vstack so that it gets stacked on top.
