  I'm trying to remove a logo from an .MP4 video format with ffmpeg on a Linux machine without re-encoding (for preserving the same quality) with the following command:
  
  ```
  ffmpeg -i input.mp4 -vf delogo=x=270:y=190:w=40:h=40 -c:a copy output.mp4

  and it gives me the following errors:
  
  ```
  Unrecognized option 'vf'

  then a new error came up:
  
  ```
  Unable to find a suitable output format for 'delogo=x=270:y=190:w=40:h=40'
  
  ```
  
  ffmpeg is always updating and it seems that they change command line arguments a lot so any material or tutorial I find online seems to get outdated quickly.
  
  I review their website documentation but can't get it to work, I think i'm missing something...?

  Your command is missing double quotes around the filter definition :
  
  ```
  ffmpeg -i input.mp4 -vf "delogo=x=270:y=190:w=40:h=40" -c:a copy output.mp4
  
  ```
  
  (as explained in [FFmpeg filters documentation](https://ffmpeg.org/ffmpeg-filters.html#Description))
  
  Nevertheless, this filter will decode and re-encode your video stream.
