CONTROL ANY MOTION Live, looping, stop motion, timelapse, GigaPixel* and Event Mode camera moves at your fingertips. DIGITAL KEYRAMING Simply move each axis into position and hit record. kOS saves your exact positioning for 100% repeatable moves. WIFI CONNECTIVITY Your CineShooter, Second Shooter Pro, or Second Shooter Plus device creates its own WiFi network that you can connect your device to instantly. COMPLEX KEYFRAME MOVEMENT Create up to 20 keyframes at once for ultra complex movement. EASY KEYFRAME SMOOTHING Add and manipulate curves to your moves for ease-in and ease-out motion. Also, link each side of the keyframe to match. EDITABLE KEYFRAMES No need to re-record the move if it's not exactly what you want. Edit one or all axes and keyframes into the perfect position. Featuring incremental, exact motor position plus tap and move keyframe adjustments. REPEATABILITY Repeat the exact same move over and over again at the same speed or variable speeds depending on the application. DELAY BY DATE/TIME Not going to be around when your move needs to start? No problem. Easily set a date/time or fixed amount of time to have your move begin. kOS takes care of the rest. FLASH MARK/BLOOP Sync up your moves easily via the built-in flash marks with adjustable delay. PRE & POST-PHOTOS (TIMELAPSE MODE) Easily add a series of head or tail photos to your timelapse move. GO TO POSITION Set minimum and maximum ranges on each axis (ie. slider 0" to 32") and go to any position by entering a value. LOAD & GO This feature allows for pre-loading a move so that you are able to start instantly whenever you are ready.

ANALOG CONTROL PANEL Manually control several axes live with the built in analog controller.
