There are a lot of people discussing the raw output option for the FX9. In particular the need to use the XDCA-FX9 adapter. First I do understand where those that think the XDCA is big, bulky and ugly are coming from. It certainly won’t win any design awards! And I also understand that we would all probably prefer to have the raw out direct from the camera body, but that’s not going to happen.
Besides which, the raw option won’t get enabled until some time next year in a firmware update. So in the meantime what are the alternatives?
Up to 30fps the FX9 can output UHD in 10 bit 4:2:2 over HDMI. At 60fps I’m led to believe that you can output 10 bit 4:2:2 UHD over the 12G SDI, but I have yet to actually test this. The ability to output 30fps UHD over SDI requires 6G SDI and the standards for 6G SDI are still all over the place, but once the standards settle I am led to believe that 6G SDI should be added via a firmware update.
What this means is that it will be possible to output 10 bit 4:2:2 to an external recorder from launch at 24fps all the way to 60fps using either HDMI, SDI or a combination of the two. So I will be looking at using an Atomos Ninja V with the AtomX 12G SDI adapter to record the 10 bit output using ProResHQ for those projects where I really want to squeeze every last bit of image quality out of the camera.
Don’t get me wrong, XAVC-I is a great codec, especially if you want compact files, but ProRes HQ will give me just a tiny bit less compression for those really demanding projects that I get involved in (for example shooting demo content for some of the TV manufacturers).
10 bit S-Log3 is very gradable. Because the FX9 has much less noise than the F5, FS7 or FS5 there will be no need to offset the exposure as I feel that you need to do with those cameras. So ProResHQ from an FX9 will be very, very nice to work with and the Ninja V is small, compact and uses less power than the larger Shogun models, great for when I will be travelling with the camera.
So while the camera won’t have raw for a while and perhaps even when the raw option does become available there are other ways to get some really great, highly gradable material from the FX9. Internal XAVC being one, but if you need ProRes you have some good options.
So What Does the XDCA-FX9 add?
I do suspect that the XDCA-FX9 is more than just a pass through for the raw data from the camera to the raw out SDI. To get 16 bit raw out of a camera is far more challenging than the 12 bit that the FS7 and FS5 produce. There must be some clever processing going on somewhere to squeeze 16 bit raw down a single SDI cable and I suspect that processing will be done in the XDCA-FX9 unit. The XDCA-FX9 obviously does contain a lot of processing power as it has it’s own fan cooling system. It does help balance the camera and the FX9 with XDCA-FX9 and a V-lock battery does sit very nicely on your shoulder.
In addition the XDCA adds a whole host of streaming and internet connectivity functions allowing the FX9 to be used for live news via 4G dongles without the need for a Live-U or satellite truck. Plus it has handy switched D-Tap and Hirose power outputs.
I do look forward to getting an XDCA-FX9 for my FX9 and look forward to the raw being enabled. But even so there will also be many cases where I suspect the convenience of the compact Ninja V with the AtomX SDI adapter will be the perfect fit. It’s always good to have multiple options.
Just to make it clear – The Ninja V cannot and almost certainly never will be able to record raw from an FS5/FS7 or FX9, only conventional component video.
