STRATUM Slit Scan vs Time Flow Sketch

-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. (*2) Synthesis rate of 30 FPS, 540p on iPhone 7 30FPS, 720p on iPhone XS 60FPS, 1080p on iPhone 11 or greater It is controlled by the GPU family. Record FHD 1080p, 60FPS with A13 or greater HD, 30FPS recording with A11, A12 540p, 30FPS recording with A10

A sketching app for reshaping the way time flows inside a video. You draw the shape of that flow as a black-and-white gradient over the clip you loaded. The brightness you paint becomes a moment in the clip, or a playback speed, so different parts of the image start running on their own time. Only where your finger traced runs ahead. Another part plays backwards. One area stays frozen while everything around it keeps moving. You can even draw time that twists — forward and backward unfolding at once. Take the single, even flow of time in a video, pull it apart, and put it back together. Reflections shifting on water, drifting clouds, the movement of familiar things and creatures: there may be something new waiting in the everyday scenery you thought you knew. ■ Main features [Making a map] • Draw — trace with a finger to draw the flow of time. Five brush tones, a bleed brush, and a smudge tool • Gradients and presets — start from a regular pattern • From motion — build the shape of time automatically from the movement in the clip • Cut & slide — split the map along a line and slide the pieces to make time slip [How the map is applied] • Apply mode — Vertical / Horizontal slit works band by band, Surface works pixel by pixel • Time map — brightness sets which moment of the clip is shown; black is the start, white is the end • Rate map — brightness sets the playback speed, from reverse to fast forward • Space map — brightness sets where on screen the picture is taken from [Checking what you made] • 3D plot — see the shape of time as a solid • Time graph — see time, rate and space as line charts [Live camera] • Time-shape the camera image as you film — it keeps the last few seconds, so the map you draw can show the past or freeze parts of the picture • Tap “Stop & capture” to turn it into a clip you can edit and export [Sound and export] • Sound — the audio goes through the same time processing as the picture • Export — save the result to your photo library as a video All video processing happens on your device, and nothing you make is sent anywhere.
