Depending on the kind of video you are making there are sometimes when you want to have a nice, fluid dolly tracking shot. Maybe you are making a landscape video or making a nature of wildlife video and you want to make the camera move, but want it to be a perfect fluid shot. This is one of those cinematic shots that you may have always wanted in your work, but couldn't do properly.
To achieve this look you usually need to have a slider rig, and these can be very expensive (even to rent). Instead of spending hundreds of dollars on one you can take a try at building one. YouTube's How To Anything shows us just how to do that -- and only for $8!
You can find all of these supplies at your local hardware store and can make it to the dimensions you need and make it specifically for your camera. If you are a DIY kind of person, this is a project for you!
