FOR-A : FT-ONE
Full 4K ResolutionUltra High Speed Camera; Up to 900 Frames Per Second; Does NOT include FT-1RU.
Video and Audio Systems for Broadcast Post-Production, and Professional Video
Description
The FOR-A FT-ONE Full 4K Variable Frame Rate Camera captures high-speed 4K video as RAW data at up to 860 fps. It shoots at a variety of frame rates including 24, 60, 120, and up to the maximum of 860 fps. It features a 12-bit CMOS sensor with 4096 x 2304 resolution, which is slightly larger than the DCI standard. The Sensor features an ISO rating of 640, and provides an image with an 11-stop dynamic range. It uses a global shutter that allows the images to avoid rolling shutter artifacts.
The CMOS sensor is equivalent in size to a Super 35 sized sensor, preserving the depth of field associated with cinema productions. The camera has a PL lens mount, allowing it to accept PL mounted cinema style lenses, as well as full frame lenses with a PL mount. The camera records 9.8 seconds of 4K footage at 860 fps, which you can play out as 4K or HD through the camera, or transfer the RAW files to available SSD modules for on camera play back. The available SSD modules will hold approximately 90 seconds of high-speed video, and can be hot swapped to transfer the footage to available storage for editing.
Features
FT-ONE features include:
- For.A developed the FT1-CMOS sensor, which is equivalent in size to Super 35mm, specifically for this camera. The sensor features 4096 x 2304 resolution, an ISO rating of 640, an 11-stop dynamic range, and a global shutter.
- The FT-ONE captures 4K images at select framerates: 24, 50, 60, 120, 180, 240, 300, 360, 420, 480, 540, 600, 660, 720, 780, and 860.
- RAW capture is recorded to internal RAM. You can shoot in 4K resolution for up to 9.8 seconds at 860 fps, while slower frame rates allow for longer recording times. Recorded footage can be transferred to available 2TB SSD cartridges, each of which can hold up to 84 seconds of material. The cartridges are hot swappable, so there is no need to power down the camera and stop shooting as you swap out cartridges.
- The internal RAM can be used as a single space or partitioned from 2 to 16 spaces for simultaneous recording or playback. Partitioning enables you to record new scenes while playing back recorded scenes already stored in any partition.
- Simultaneous 4K recording and playback are supported by using 1080p HD-SDI signals. In addition, 2 downconverted HD-SDI outputs allow you to monitor the signal on a preview monitor and a viewfinder with an on-screen information display.
- Constant image capture begins as soon as this camera is turned on, and it continues to overwrite the internal RAM until the record trigger is pressed. The record trigger has three settings:
- Start - records to available space on the partition, beginning with when recording was triggered. End - saves the images recorded prior to triggering the recording.
- Center - saves the video before and after recording is triggered, up to the amount of available space on the partition.
- The high-speed global shutter system counteracts rolling shutter artifacts that might otherwise occur with fast motion.
- For-A's 12-axis color correction allows the FT-ONE to match the output of traditional cameras. This adjustment only affects the camera's video output, and does not affect the RAW files.
- The camera accepts genlock signals allowing it to seamlessly fit into an existing mobile or studio system.
