The Shootools AutoPan is a clever product from Shootools that adds a motorized second axis to any linear slider (or crane). A simple device that has it's own built in rechargeable battery and can quickly be setup and programmed to repeat keyframe positions.
My video only shows the basic use of the Shootools AutoPan, as their Wireless App is not yet available. Once it becomes available you'll be able to remotely control and configure the AutoPan and perform more advanced Timelapse movements. There is even a Table Top that can be added on the AutoPan transforming it into a Motorized Rotating Product Table.
Now as I have mentioned in my video, there is noise when the AutoPan is tracking. So for audio sensitive projects like 'sit down interviews' this is probably not ideal. But for certain types of projects focused mainly on imagery such as Products, Food, Car Shows, Weddings details, Real Estate, Architecture, and Music Videos, I can really see the Shootools AutoPan adding a lot of benefit simplifying tracking and that unique parallax effect. These types of moves on a slider certainly add a bit more production value to your final project.
If you're looking for a super lightweight affordable motorized Time Lapse slider, here's an interesting Motorized 2-Axis Auto Panning Slider that was sent over from DigiSlider. The Auto-panning addition allows the slider to keep a subject in the center of your frame while in motion. Here's a video overview and a short Time Lapse sample towards the end of the video.
Unlike a basic motorized slider that has moves constantly, the DigiSlider Controller can be setup for true shoot-move-shoot settings. This allows you to work with long exposures as you can configure the slider to wait to move until your camera is done firing - preventing blurry images.
It's also possible to use the DigiSlider 2-Axis as a real time Auto Panning (parallax) video slider, and you can dial in different speed settings. But keep in mind that there is audible noise from the motor so it may not work well for interview settings or where audio is critical.
The design of the Auto Panning option is clever as it doesn't require a motor like other 2 or 3 Axis Motorized Sliders. This makes it very fast and simple to setup, but this design is also limited how far you can Pan the camera inwards to keep a subject in frame. Your subject cannot be too close for Auto Panning to work effectively (angle would be too great).
Also, keep in mind that this slider is setup with a motor and belt drive, so you cannot move it manually by hand. To move the slider it has to be connected to the Controller. Unless of course if you disconnect the belt drive using a basic hex tool, then you can use the slider by hand for times you don't need the motor, and you will still have full access to the Auto Panning feature.
