Sony HXRIFR5 4K Recording Solution

Sony to launch HXR-IFR5 Interface Unit that Realises 4K recording on the NEX-FS700
Sony today announced the launch of the new HXR-IFR5 interface unit which will connect the NEX-FS700 camcorder and the AXS-R5 RAW recorder. With this combination, 4K RAW recording will be available with the NEX-FS700.
By applying a firmware upgrade to the NEX-FS700, 4K/2K RAW output via the 3G HD-SDI terminal will be available. The new HXR-IFR5 interface unit is equipped with an SDI terminal that can be used to input RAW data from the camcorder and pass the data to the AXS-R5 RAW recorder. AXS-R5 is able to record RAW data onto an AXS memory card.
The frame rates in 4K (4096×2160) recording mode are 24p, 25p, 30p, 50p and 60p. In 4K mode, 120fps high speed recording will be available for a limited duration of approximately 4 seconds. In 2K (2048×1080) recording mode, continuous 240fps and 120fps shooting will be available at unlimited durations.
The workflow to process RAW data will be exactly the same as the RAW workflow used in the combination of the existing CineAlta™ 4K cameras, PMW-F55/F5, and the AXS-R5.
Expectation of access to and interest in 4K is becoming greater, even in the low cost content creation market. The combination of HXR-IFR5 with the NEX-FS700 and the AXS-R5 will be a perfect choice, and will expand the possibilities of content creation to the next level.

Basic Features of HXR-IFR5

External RAW recorder for NEX-FS700 via SDI
The AXS-R51 docked onto the HXR-IFR5 will become an external RAW recorder for the NEX-FS7002. Connection with the NEX-FS700 will use a single 3G HD-SDI cable, therefore various shooting styles are possible. The NEX-FS700 can become a camera head when used separately, or it can be used like a camcorder if the whole system is mounted onto a rig. Sony has provided a 1/4 inch screw hole for those kinds of rig solutions. HXR-IFR5 will use the power source on the AXS-R5, and the AXS-R5 can be powered by a BP-FL75 lithium ion battery pack or an external DC 12V power source using the XLR 4 pin power input.

16 bit linear RAW recording onto the AXS memory card
The combination of the HXR-IFR5 and the AXS-R5 makes recording 16-bit linear RAW files onto an AXS memory card possible. Thanks to the 16-bit linear RAW recording, the full potential of the 4K imager on the NEX-FS700 – its broad latitude and high colour resolution – can be captured in the recorded RAW files.
Using the AXS-CR1 card reader, recorded RAW files can be easily transferred to a PC and the “RAW Viewer3” software provided by Sony used to view, process and also do some simple colour grading on the files. Not only high quality motion picture footage, but high resolution 8.4M still pictures can also be captured.

4K/2K high speed shooting
Other than 4K (4096×2160) recording at 24p/25p/30p/50p/60p, 120fps recording in 4K resolution is available for approximately 4 seconds. Also, in 2K (2048×1080) recording mode, 240fps/120fps high speed continuous recording is available for unlimited time. These high speed recording modes4 are only possible with the combination of NEX-FS700, HXR-IFR5 and the AXS-R5.

AVCHD simultaneous recording on NEX-FS700
Even in RAW recording mode5, NEX-FS700 can simultaneously record AVCHD onto the camera’s memory card. The recorded AVCHD files will have the same time code as the RAW files, meaning the AVCHD files can be used as proxy files for off-line editing.

HD output for monitoring
HDMI/component/composite video outputs on the NEX-FS700 and the AUX OUT of the AXS-R5 can be used for monitoring purposes. In order to achieve accurate monitoring of the wide dynamic range made possible by RAW recording, Sony has added S-Log2 settings to the picture profile of the NEX-FS700.
