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.

*According to internal research as of May 2012.

Sensor Comparison


Storage partitioning

  • The internal memory can be used as a single partition or divided 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.

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

  • Counteracts rolling shutter artifacts that might otherwise occur with fast motion.
  • Capture instantaneous subject movement in crisp detail at 4K resolution.

Simultaneous 4K recording/playback


  • Real-time 4K output. Auto-switched from real-time output to playback when slow motion playback.
  • 3G-SDI x 4 output for 4K resolution
  • HD-downconverted VF OUT and AUX output
  • Menu can be displayed on VF OUT.


  • 2-ch simultaneous 4K (QFHD) output (CH A and B)
  • CH A for live, and CH B for slow motion playback output.
  • Output for return RET 1, RET 2 as well as VF OUT and AUX output.
  • Others

    • Genlock input
    • 12-axis color correction
    • 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.


      • Inheriting the features of FT-ONE, offers the extra mile by carrying camera signals much farther via optical cable.
      • Base station FT-1BS can power the FT-ONE-OPT(max. distance: 1 km)
      • Supports genlock signals
      • Intercom for broadcast scenarios or emergencies
      • Switchable output: VF OUT, RET 1/2

      HD capturing mode (FT-ONE-OPT)

      • Max. 1670 fps in 1920x1080 resolution, and max. 2000 fps in 1920 x 888 resolution.
      • 4 outputs of each CH A and CH B. OUT 1 and 2 for HD-SDI, and OUT 3 and 4 for 3G-SDI.


      SSD Cartridge


      • 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.

      Cartridge Docking Station


      • Provides USB 3.0 connectivity between the FT-ONE SSD Cartridge (FT-ONE2T or others) and a computer.
      • Copy material from the SSD cartridge directly to storage on the computer or to an attached HDD or SSD
      • Color gamut adjusting, 3D-LUT creating, and easy computer-based playback of material on the SSD cartridge
      • Can be used outdoors when powered via the IDX battery mount.

      Remote Control Unit


      • Includes direct recording and playback buttons, as well as a rotary encoder and touch-panel for a range of settings.
      • Facilitates camera setup, recording, and playback.
      • FT-1RUA with a playback controller with a fader control

      Remote Control Panel


      • Real-time remote image adjustment for FT-ONE material.
      • Efficient, intuitive adjustment via dedicated buttons for iris, pedestal, gain, and other settings.
      • In conjunction with the FT-1RU, offers powerful support for FT-ONE cameras.

      DPX Converter


      Converts 12-bit RAW data on the FT-ONE SSD cartridge to a common file format for editing or color grading purposes.




      FT-1READ screen


      Base Station

      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
