Timetracks4D vs STRATUM Slit Scan

Timetracks4D is a camera that cuts time out as if it were space. Think of video as a cube stacked in three directions: width, height and time. Ordinary playback cuts that cube straight across time and shows you the slices one after another. Timetracks4D tilts the cut. Once it is tilted, every place on the screen shows a different moment: whatever held still comes out as it was, and only what moved is twisted. ■ Two ways to shoot [Movie] Records while the cut turns. The tilt changes from frame to frame, so the picture keeps moving. Angle, Speed and Window Time change how it twists. [Still] Builds one picture by stacking narrow bands, one at a time. Each band was taken at a different moment, so the finished picture reads as the flow of time from top to bottom. This is the slit scan, the way the first Timetracks worked. It saves a long picture: eight screenfuls joined end to end, each at the camera's own resolution. Both are made from the same camera feed, but they treat time differently, so each one has its own settings. ■ Main settings - Camera (Back / Front), Zoom (Lens), Resolution, Frame Rate - Transform (Shear / Rotate) and the edge time runs along (Long Edge / Short Edge) - Auto Rotate speed, Angle, Window Time - How the band moves (One-way / Palindrome / Wave / Fixed / Drift / Random) - Interval between bands, from single frames to hours - Scan Width - Full Screen, Show Buttons, Touch Gestures, Prevent Auto-Lock - Add Location There is a button that randomizes the settings. If you are not sure what to touch first, press that. ■ Getting a good result Hold the device still. If the device moves, the whole picture moves with it and you cannot tell that apart from the subject moving. A tripod or a table is the sure way. Point it at something that moves. A still subject seen from a still device gives the same picture at every moment, so nothing happens. People walking, a hand, water, traffic, anything swaying in the wind - these work well. Once you have the feel of it, try moving the device instead. That is where the more complicated shapes come from. ■ Pricing Everything except recording is free. Play with the camera and the settings as much as you like; the picture you would get is on the screen already. Try it first. Full Access (a one-time in-app purchase) removes the ad and lets you save movies and stills. If you have already bought Timetracks, you do not need to buy anything. Full Access turns on by itself when you update.

-Features- • Eight kinds of slit scans are possible with four kinds of slit patterns and reverse scan. • Tap the shutter button to take a photo. • Press and hold the shutter button or drag to the right to start recording. • Models with a high-speed camera can shoot at 240 to 1 FPS. • The slice size (number of strips) can be set up to around 500. (*1) • Manual focus lock, exposure adjustment •Use the camera flip button to switch between the inside and outside cameras. You can switch to another camera such as a triple camera by pressing and holding it. • Equipped with external display output for performance art and installation. • You can preview the taken photos and videos in the app. -Overview- Slit scan is different from the actual time when shooting with an analog camera by attaching a paper with a slit in front of the camera lens, lengthening the exposure time and moving it in the vertical direction with the slit. It is a technique to take the exposure of a single photo. Strictly speaking, STRATUM does not install a slit in front of the camera like slit scan, but it stores digitally captured data in memory, slices it in any direction, combines it for each frame and shoots in real time.  Due to the remarkable development of mobile devices in recent years, STRATUM has accumulated about 500 FHD images of 240FPS (*1) high-speed camera equipped with iOS, and composites and takes 500 photos at a time at a high frame rate of 60FPS. -Spec- In Stratum, each device limits the composition rate and the size of the composite image in order to perform the most reasonable processing possible for each device. The composite rate is different from the shooting rate. Any model capable of high-speed shooting can shoot at 240 FPS.
