Here's a quick lesson on the ease of putting together a "Quick Cut' video.
I was asked to help-out with some camera & production work for the New Hyde Park Museum during their street fair on September 21st. Just shooting yourself or participant while talking and later putting a few finishing touches with a basic movie editor like Windows Movie Maker, allows for a social video post (YouTube/Facebook etc) with all the SEO benefits.
Do as many 'takes' as necessary and get it in-the-can as they say for editing out the flubs later. When you edit, you can chose the beginning & end of the piece, maybe adding a title or simple fade-In's & fade-Out's.
