Video without the audio

Short videos can fit really well into a presentation. The audio track can be a problem.
  1. Bombastic loud music can feel out of tone, especially if the sound was not set up correctly (too loud, too soft)
  2. A spoken voice over might feel out of tone with your overall presentation
  3. It is hard to edit/change video audio, maybe your message has changed over the past month, the voice over of your video has not
A good option can be to run a silent video, where you the presenter, gives live commentary in a voice the audience already has gotten used to, perfectly blended into your overall story.
