I've been reading about DIY camera sliders which seem as complicated as a Rube Goldberg drawing. I woke up one morning with a thought: A rain gutter. Well, at Loew's, I was looking at the gutters and found them to be too flimsy, so I went to the irrigation supply section. There I found the Spee-d drainage system. Teh troughs were in 4' and 10' sections and there were grates to cover the sections with. I grabbed a 4' section and a 2' grate...some 1/4" screws and washers and off I went. I tried a test video at the waterfalls at Inverrary, FL and edited half-speed with Magic Bullet Looks Green Pearl with a shift to blue, Pinnacle Studio Ultimate 12.
