ATOCH CFAST to SSD Adapter

People have been using CFAST to SSD Adapters for the Ursa Mini cameras ever since the beginning, and i've used the ATOCH adapter myself. It sure comes in handy, but what I didn't like was all of the loose cabling and the extra bulk. So whenever possible I just stuck to CFASt cards. It kept my rig light and tight.

Blackmagic Design Ursa Mini Pro SSD Recorder

Now BlackMagic Design has introduced their own SSD Recorder (only for Ursa Mini Pro), that connects between the camera and the battery plate. It's much cleaner with only two wires that record from the SDI input and output, but it does have it's caveats. For one, the BM SSD Recorder only works with the 'Pro' version as it records from the SDI. When using the SSD Recorder, you can't connect the camera to an ATEM for live production. With only one SSD drive, it also can't record 4.6K Lossless RAW at 60p (only supported to 30p).


Clean Aftermarket CFAST to SSD Adapter

That's what makes this new aftermarket 'DUAL SSD Recorder' very interesting. It works very much the same as other CFAST to SSD adapters, but it's been designed to fit clean behind the battery plate (exactly like Blackmagic's design). The advantage is that because they are still using the CFAST adapters, you can record full RAW, full resolution, and all at the fastest framerates. In fact because this adapter uses (2) SSD Drives, you can even turn on 'Dual Card Mode'! And there's no bias for Ursa Mini Pro cameras, it is backwards compatible to any Ursa Mini camera - and you'll still be able to use the SDI out if you're hooking up to an ATEM.

There's not much to complain about this aftermarket Ursa Mini SSD Recorder except for the fact that you won't be able to close the LCD screen completely with the CFAST cabling running through. But that's about the only con I can think of...

One of the drawbacks of shooting with the BlackMagic Design URSA, URSA Mini 4K/4.6K cameras are the requirement to use CFast cards as recording media. I guess you can use an external 4K recorder, but that's not going to allow you to record Full RAW. Even cheap 256GB CFast cards capable of handling the URSA will run about $600 dollars/each (seen here).

In the video below, i'm showing you the Atoch C2S Adapter that allows you to record to SSD Drives instead of expensive CFast cards. With this setup, you'll still be able to record in any format the URSA offers, including full uncompressed 4K RAW at 60p.

Yes I know, it's an additional accessory you need to mount to your camera, but can literally save you thousands of dollars in storage costs. It may not be a full replacement for every situation, but when you're just working handheld or on sticks, it's the most inexpensive way to capture high quality footage from the data hungry BlackMagic Design URSA Cameras.

If you're the type to shoot mainly in low quality ProRes, lower framerates, or just 1080 then almost any SSD drive will work. But in order to capture the highest quality from the URSA 4K RAW 60fps, then you'll want to choose a decent SSD Drive. Recommended is the Sandisk Extreme Pro drives or the Samsung Pro SSD drives.

With about 960GB of storage (2 480GB SSD Drives), you're looking at around 2.5 Hours of 4K ProRes HQ at 24p. Every so often I may switch to 4K 60p, or 1080 120fps, but I seem to have enough footage for a decent project. The quality coming off the " target="_blank">BlackMagic Design URSA Mini 4.6K is so nice, I don't even mind shooting in ProRes LT if I need more than 2.5 hours. But even if I had to buy more storage, i'm literally saving thousands of dollars using the Atoch C2S Adapter and recording to SSD over CFast.
