The full potential of the 55mm diagonal length large format sensor in the GFX can be seen when shooting both stills and in video. The combination of the latest sensor and the “X-Processor 4” enables support for 4K/30P video. The camera’s sensor, which is larger than that of most cinema cameras, produces a shallow depth of field, enhanced tonal gradient in 10-bit output, and greater ISO sensitivity. The large format size produces video footage with more detailed textures while reproducing three dimensional definition. You are able to capture the atmosphere of the scene unlike anything before. All the Film Simulation modes can be applied to video as well, including “Eterna,” which replicates the look of FUJIFILM’s cinema film of the same name. Furthermore, the camera supports the digital cinema aspect ratio (17:9), compression codecs such as H.265 and H.264, and a bit rate of up to 400Mbps.
With its large format sensor, the GFX100 demonstrates its appeal in video recording. It uses full sensor width to record video in 4K digital cinema format in the aspect ratios of 16:9 / 17:9. The sensor area used is greater than that of cinema cameras that support a large format sensor. You can use GF lenses and adaptors to achieve a variety of videographic expressions that only large sensors can deliver, and record them in high-resolution 4K video.
The GFX100 is capable of recording F-Log, characterized by a gamma curve with a wide dynamic range, and capturing video in HLG (Hybrid Log Gamma), one of the formats defined in the ITU-R BT.2100 international standards. Coupled with color information attained in 10-bit color depth, the camera records premium quality footage faithfully depicting scenes even with a large brightness range or subjects with high color saturation.
The high speed image processing engine, X-Processor 4, can read and output condensed video data, feeding 4K/30P 4:2:2 10bit data to the HDMI port and recording 4K/30P 4:2:0 10bit data to an SD card (when H.265 is selected) up to 400Mbps *1. You can also choose All-Intra *2 / Long-GOP, etc. The processor’s enhanced capability means video footage can be viewed on the camera’s LCD screen as well as on an external monitor whilst you film, while feeding uncompressed data straight to a recorder.
GFX100 will be able to output maximum 4K/29.97P 12bit RAW video data using HDMI to an ATOMOS NINJA V, in Apple ProRes RAW. New firmware for NINJA V will be released by ATOMOS. RAW video data gives maximum flexibility for exposure adjustment or color grading in post-production for professional videographers.Also, simultaneous output of RAW with Film Simulation / F-Log / Hybrid Log Gamma (HLG) is also available.
・Combining the GFX 100 with Gimbal / Drone that supports this function, will allow users to start / stop video recording, specify exposure settings for video (shutter speed, aperture value, ISO sensitivity and exposure compensation), and make manual focus adjustments. Guilin FeiYu Electronic Technology Co. Ltd., Shenzhen Gudsen Technology Co., Ltd., SZ DJI Technology Co.,Ltd. and ZHIYUN (alphabetical order) have announced the intention of offering compatible products.
