Ursa 4K RAW
on Nov 17, 2014 at 1:42:36 am

I am very much interested in this Ursa Cam.

How ever, I really want to record in 4K RAW and the onboard cards will not record a lot of min and are very expensive.

Does any one know of an external device that can be hooked up to film for instance in SSD or other formats? But still be able to film in 4K RAW!

The URSA doesn't have a RAW output, so no external RAW recorder is possible. Also, if the URSA's media cost is too much, any of the external RAW recorders would be certainly way too much for you.
Consider the BMPC, it records 4K RAW to an SSD internally, for a much lower cost per minute of recording than the URSA.

SanDisk recently reduced prices. It's still expensive, but better.

I plan to get a couple of these relatively inexpensive Super Talent 64GB CFast 1.0 cards and shoot in ProRes until the prices of the SanDisk and Lexar 2.0 cards come down.

Each card gives you about an hour of recording time in ProRes.

Good luck!

I think Atomos also has lower cost CFast1.0 cards.

Unfortunately for Atomos, their prices are not even close. As of this post, the Atomos 64GB CFast 1.0 card is $159, while the Super Talent 64GB CFast 1.0 card is on sale for $55.69.

As with SD cards over the last few years, when the Taiwanese and mainland factories crank up, prices will plummet.

Cheers,

I haven't personally tested any CFast 1 cards on the URSA, but using them will be extremely limited. At about 80 MB/s write speeds on a 64GB card, you're looking at a format cap of about 4K 25p PreRes 422 with a record duration of about 15 minutes. Conversely, 1080p60 PreRes HQ will theoretically work (about 62.2 MB/s) at a record duration of about 17 minutes. 1080p24 ProRes HQ would give you about 42 minutes.

Agreeing with Bill, the Cfast 2 cards WILL continue to drop in price and get larger in capacity. I see a lot more worth with cards that are at least 128GB.

Hmmm, so if I want to film 4K RAW this camera is basivcally not ready as far as the available cards (if not for ridicioulous prices).

I love the cam, but sorry, it was all about filing 4K RAW for me on this amazing camera. Sounded too good to be true.

Hope soon we will have reasonable priced cards available.

[Ali Quintana] "Hmmm, so if I want to film 4K RAW this camera is basivcally not ready as far as the available cards"

The URSA has been 4K RAW ready since the first day of its public release. The question asked was in regards to CFast 1, which may not even work correctly (I have not tested it myself). The URSA was designed from day one to use CFast 2 cards in the same manner the ARRI Amira was designed. Having used CFast 2 cards with the URSA in real world productions, I can attest that the performance of CFast 2 is spectacular. Prices have come down on CFast 2 and will continue to do so.

If you want to shoot 4K RAW on the cheap, then the Production Camera 4K using SSDs is your best best, but you will not have all of the other advantages the URSA provides including 60p now and 120p down the road.

Yes, guess need to wait a while for the Cfast 2 to come down in price.

I have the BM prod camera 4k and the 2.5, really great cams. Nice pics. So that will do for now. Can alwasy buy a Ursa tomorrow.

Looks like a real great cam, cant wait to get my hands on it.

It won't be long. Lexar 32GB CFast 2.0 cards are priced at $179.99 and will start shipping in a few weeks.

Thats great news...

What about bigger cards? to film Raw, is 32 not a bit to little?

Re: Ursa 4K RAW

Personally speaking (and using 120GB cards on the URSA), the 32GB cards aren't a viable solution. At 4Kp24 ProRes HQ you'll only get a little over 5 minutes of recording time. Even 1080p24 only gives you 21 minutes of recording time. 4Kp60... only 2 minutes, LOL. Forget RAW with 32GB. Even the new RAW 3:1 will only give you minutes worth of shooting.

Think of it this way... would you ever use a 32GB SSD on your BMCC or especially the BMPC 4K? No way. Just too small.

120GB is really the bare minimum the URSA should be using in my opinion. Then the camera will really shine!

You're right. I hadn't heard of Super Talent. Not only are they less expensive, they have better performance specs.

I use SanDisk CFast2 cards in our URSA for their reliability. Over the years I've always used SanDisk products.

Few days back i have bought a new URSA with its new V2, 4.6k sensor on board camera and started to do test shoots. It was so disappointing to see that its Iris control is not working for EF lenses. And the raw file folder is not carrying a XML file in it. So its not possible to edit or convert the DGN file sequence in any kind of softwares including Resolve. I dont know what to do with it. I have contacted technical team of BM but they also not sure about it and asked me deal with the service center

Hello people! Since we are talking here about cfast cards and 4K raw recording, I would like to ask you about a device that can handle 2 ssd drives and shoot on URSA 4K raw @120fps? Do you people think it's a good idea? :)










Thanks!

With this device on URSA you can have 4K RAW@120FPS, and if firmware allowed, 4K RAW3:1@160FPS!

Simply: our device is like a Cfast extender , but instead having 2 Cfast on other hand you have 2 fastest ssd drives!

RAW would be recorded to the SSD and you'd copy the SSD RAW data to your NLE.

AFAIK, URSA doesn't "output" RAW from any BNC connector. It records it internally to CFast 2 cards, or this SSD adaptor which replaces the CFast 2 cards.

Ricardo, how do you output RAW from URSA today? You simply insert 2 CFast cards and shoot. You know what a couple of hours can cost you. CFast cards are "mini" SSD drives, so we made an "adapter" that allow you to use SSD drives on URSA!
Thanks!

Ricardo, in the pictures above you can see the RexToast that you must fix with 4 screws between back of URSA and battery plate. Then, you have a LEMO input on RexToast where goes a cable. On one hand of this cable you have a LEMO plug, on another hand this cable have 2 Cfast housing that goes in place of Cfast cards.
Thank you!
