  Basic command is
  
  ```
  ffmpeg -i in.mp4 -vf crop=iw:ih-25:0:0 -c:a copy out.mp4
  
  ```
  
  Note that MP4s usually require the dimensions to be even, so the command above will actually crop 26 pixels from the bottom.
  
  On linux, using bash, the script would be
  
  ```
  #!/bin/bash
  # Usage: ./crop.sh
  
  mkdir cropped
  for file in *.mp4;
  do
      ffmpeg -i "${file}" -vf crop=iw:ih-25:0:0 -c:a copy "./cropped/$file"
  done
  
  ```
