The ultimate 4K solution for super-slow motion

The world’s first* high-speed camera designed for super-slow-motion acquisition at 4K resolution up to 900 frames per second (fps). The FT-ONE incorporates the groundbreaking FT1-CMOS, a global shutter CMOS color sensor. The FT-ONE CMOS was developed by FOR-A to provide superior resolution and sensitivity. RAW material is recorded at high speed to the internal RAM memory, which holds nearly 10 seconds of 4K content shot at 900 fps. For convenience, material can then be transferred to optional internal SSD cartridges. Unleash your creativity with this unprecedented innovation in super-slow-motion video at 4K resolution.

FT-ONE 4K Digital Intermediate Workflow

Advanced FT1-CMOS sensor

Creating a high-speed 4K camera required a new kind of sensor. Drawing on our expertise in high speed cameras, we devised a CMOS sensor equivalent in size to that of super 35mm sensors. A unique sensor for a revolutionary camera, FT1-CMOS sensor offers outstanding sensitivity, responsiveness, resolution and transfer speed.


Super-slow motion in 4K at 900 fps

The advanced FT1-CMOS sensor enables high-speed recording at up to 900 fps. The massive 4K image data from the sensor requires powerful image processing. Material is stored in internal memory in real time. The frame rate is also adjustable (24 fps min. base level). The FT-ONE maintains a striking 4K resolution at all frame rates.

11-stop dynamic range

The 12-bit FT1-CMOS sensor provides a high dynamic range across 11 stops. What’s more, ISO 640 sensitivity ensures stable, extremely low-noise results.

Storage partitioning

The internal memory can be used as a single partition or devided into 2 to 16 partitions for simultaneous recording or playback. In continuous recording, material can be left intact before recording the next segment. Partitioning allows you to record new scenes while playing back scenes already stored in other partition.

Simultaneous 4K recording/playback

Simultaneous 4K recording and playback are available. While a native 4K material divided into four 1080p HD-SDI signals is output, another 4K material down-converted to HD-SDI in size can be simultaneously output. In addition, two downconverted HD-SDI outputs allow you to monitor the signal on a preview monitor and a viewfinder with on-screen information display. Any segment during 4K recording can be extracted for viewing in HD-SDI (1080i). As the next segment is continuously being recorded, even during slow-motion playback from the camera, this dual-channel output helps you avoid missing out on crucial moments.

Versatile trigger support

Constant image capture begins as soon as the FT-ONE is turned on. Pressing a trigger that can be set to record from the start, center or end of the event to be captured, starts recording to internal memory. Choose the optimal recording trigger for the subject or scene. With the pre-roll function, playback starts from the specified position, keeping playback focused on required segments.

Global shutter system

The high-speed global shutter system counteracts rolling shutter artifacts that might otherwise occur with fast motion. Capture instantaneous subject movement in crisp detail at 4K resolution.

12-axis color correction

Color correction along 12 axes during video output surpasses ordinary trichromatic correction. By adjusting the hue and saturation for individual colors on the 12 axes, you can isolate specific colors for correction. Our 12-axis color correction system allows for the unprecedented ability to perform onsite color adjustment and match the output of traditional cameras. 

(This form of adjustment only affects video output and none of the camera memory RAW material.)

Genlock input

Genlock functionality was designed with broadcast scenarios in mind. The FT-ONE has been designed to fit seamlessly into existing mobile and studio systems.

Multi synced video capture (planned for future support)

The FT-ONE supports synced shooting using multiple cameras. Synced camera mode is perfect for recording and playback, e. g., when covering the same subject with multiple cameras, or using two cameras in a 3D rig. In high-speed acquisition, the slightest discrepancy in timing is very noticeable, which makes synced shooting and playback a key feature.

Model with Fiber-Optic Connectivity


The FT-ONE may be impressive, but the FT-ONE-OPT goes the extra mile by carrying camera signals much farther via optical cable. Used with the optional FT-1BS base station, the camera can be used in live outdoor coverage, in a studio setup, or in other applications requiring long-distance transmission.


  • Can power the FT-ONE-OPT (max. distance: 1 km)
  • Gigabit Ethernet connection
  • Also carries genlock signals
  • Intercom for broadcast scenarios or emergencies
  • Switchable output: VF OUT, RET 1/2


Transfer material recorded on the FT-ONE to an SSD cartridge. One FT-ONE2T cartridge holds up to 84 seconds of material. An economical cartridge with half the capacity is also available: FT-ONE-1TL.* The FT-ONE accommodates two cartridges which can hold nearly 3 minutes of material in all. Switch the hot-swappable cartridges as needed when shooting.

* Not suitable for real-time playback, due to low frame rates.   

4K extraction system

The "Spot zoom" feature, which extracts HD frames from 4K footage, is gaining acclaim as an instrument that allows 4K footage to be utilized within HD content, especially in sports applications. Developed by FOR-A to fulfill market requirements for this spot zoom feature, the 4K extraction system with touch panel operation offers intuitive ease-of-use functions, such as when adjusting zoom magnification and designating extraction parameters. Operating with the FT-ONE, you can specify IN/OUT and midpoint view angles for slow motion replay from the touch panel. The 4K extraction system allows pinpoint zoom-ups of super slow motion replays and the creation of remarkable scenes.

  • Extract HD (1080i or 720p) output from QFHD (1080p × 4) input
  • Isolate and enlarge the action in scenes
  • Easy touchscreen-based framing and extraction
  • Smoothly zoom in or out

Compatible with FT-ONE high-speed 4K cameras

  · Simulate dynamic and flowing camerawork by setting desired replay extraction points and frame sizes

  · Perfect for capturing the excitement by zooming in to the action in slow-motion replays
