Here are some examples of work that would be relevant to your project. The aim of capturing footage at TEDx is to share the knowledge and to drive innovation, which I imagine would apply to Yow! too. We created a promo for the TEDx that puts emphasis on ideas which tends to get more shares on social: https://vimeo.com/173434557 This got some great traction on Facebook because it sparked conversations about adventurous minds.
After the event we created this highlights video for their event that got about 25.000 views: https://vimeo.com/182789811/fa6d84cb88
They keynotes varied from 4000-80000 views: https://vimeo.com/178271815 And of course there was Kristine’s presentation! https://vimeo.com/183255180
One interesting outcome of our TEDx project was the traction we got with our One Minute Thoughts pilot. The One Minute Thoughts got 114000 in the first week alone on Facebook. The reason is that short form content that starts conversations gets shared on Facebook, which rapidly expands the viewer base. https://vimeo.com/176713858 https://vimeo.com/175901512 What ideas could we share that will spark conversations with your audience?
Here’s an example of how we approached this for the Walkley Foundation’s Storyology Conference: https://vimeo.com/182352472
