In episode 264 of Semantic Mastery's weekly Hump Day Hangouts, one viewer asked how to create a clip to promote an upcoming live event video.
The exact question was:
Hey guys I’m publishing a video in 2 weeks using Live events but I want a smaller version of the same content online right away for other traffic reasons, how can I do that? What needs to be different between the 2 videos? Can I take some of the video content and audio from the permanent 2nd video and use that in the first temporary video?
