Videos are central to a great crowdfunding campaign. In fact, according to Kickstarter, "projects with videos succeed at a much higher rate than those without (50% vs. 30%)."

You should try and get the best video possible and make sure it's professional looking.

You can create a professional looking video for less than $600 with resources from these sites:

• Go to AudioJungle.com for music, sound effects etc.
• Go to Graphicriver.net for special effects
• Go to Fivrr or Piehole for voice overs
• Check out Elance, Odesk or freelance for someone to put it all together if you don't have the skill.
