Your basic Jib / Crane will give you smooth vertical (up/down) movements. With a pan head placed under the crane, you will combine both horizontal (left/right) and vertical movements. Attach a video head to the end of the crane and you’ll be able to maintain a subject in frame even when the crane is panning horizontally similar to a track dolly or slider. That’s quite a bit of options for a crane, but once you’ve added a motorized pan/tilt head, it will open up amazing camera movements that are otherwise impossible to achieve through any other tool.
