Comments.Text: @Gyan no matter what video I convert, I just don't understand from those specifications what type of codec / bitrate etc... I need to set to `ffmpeg` in order to make the projector read it, that's why I'm asking to more expert people about the topic

  now I'd like to be able to reproduce my videos on it by simply converting them before reproducing on the projector.
  
  I use Linux, what command could I use to convert a video?

  Is there a general command I can use for all my video files and that does not required too much time to convert?
  
  I tried:

  ```
  
  but the projector keeps saying `Codec is not supported` when entering the USB drive and trying to reproduce the video.
  
  Thanks a lot!
