Answers.Text: You'll have to resize either the field outputs or the full frames, since the latter is double height. You're better off extracting the fields and frames individually and then renaming the files using a script.

  Sure, you have to combine the field extraction with interleaving.
  
  ```
  ffmpeg -i video.avi \
         -filter_complex "[0]field=top[t];[0]field=bottom[b];[t][b]interleave" -r 50 fld%d.png
  
  ```
  
  where the `r` value is double the original frame rate (or the same as the field rate).
