Is it possible to record the high frame rates that the Fs7 is capable of ,for example 120fps onto an external recorder like the Atomos Shogun 7? Is this possible by using the existing sdi out. And what about in the case of recording 4K 60fps which i believe is the maximum frame rate the Fs7 does in 4K. Is it a case of connecting an Atamos 4K recorder via the sdi output or do I need the Fs7 RAW adapter dock. Thanks in advance.
The Sony XDCA-FS7 Extension Unit is required to output 12-bit 4K RAW footage to external recorders. This would be up to 59.94p and up to 60fps. It's been a while since I've done this, but I believe in 2K RAW you can get up to 240fps.
In addition, you would need it to do built-in ProRes 422 1080p recording and for Genlock/Timecode connectors if you are doing multi-camera shoots.
A Shogun Inferno can record up to 10-bit 422 ProRes/DNxHR. Up to 4K at 60fps and 2K at 240fps.
