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. CAMERA PRE and POST ROLL Trigger your camera to start recording any amount of time before the move begins and when to stop after the move ends. ANALOG CONTROL PANEL Manually control several axes live with the built in analog controller. EVENT MODE Event mode is mainly intended for live events or scenarios where exact position recalling on-the-fly is needed. For example, if you are filming a live concert, you can have different positions on stage saved. You can move easily from the drummer, to the guitarist, to the lead singer and so forth. This mode is also great for repeatedly hitting actor marks on set. GIGAPIXEL GigaPixel is traditionally used for 360 degree virtual tours, panoramic photographs or GigaPixel images which are extremely high resolution photographs that are compiled of many lower resolution photographs. GRAPH EXPANSION Expand the graph with one touch when precise key framing is needed. SCRUB THROUGH MOVE Need to edit a key frame or see when the camera will be in a certain position? Use the scrub feature to instantly move to a desired position. LOOPING Looping is made easy with kOS. Simply select one-time or continuous looping. CAMERA CONTROL Set CineShooter, Second Shooter Pro, Second Shooter Plus device to trigger or control your camera’s exposure time within kOS. AUTO TIMELAPSE CALCULATION Enter your desired clip length and frame rate, then kOS will calculate the run time needed. BUMP BUTTONS Move in very small increments to ensure a precise camera position. DROPBOX INTEGRATION Upload saved moves directly to your Dropbox account within kOS app. MOTOR CONFIGURATION Each axis is able to be customized with individual features such as run speed, dampening, smoothness of curves, bump button, and axis naming.
