Body: <p>I have 50 videos all in the same folder and I know FFMPEG is frequently used for this type of work. I would like to learn how to navigate ffmpeg but if there are other free softwares I don't mind using those. I would prefer working in the command line to slow down videos mainly. Audio is less important but a nice to have.</p>
  <p>Thank you for your help in advance.</p>
