URSA 1.9.9 4K 3:1 Raw

This format brings a great improvement in media usage and recording times. Does anyone know a way to use the resulting recordings outside of the camera? Adobe has no idea what to do with this and my DaVinci Resolve (11.1.1) won't display the images either

You have to switch your Debayer to quarter quality likely if your specs are right in your signature.

Your iMac probably can't handle the full 4K Debayer, but at quarter you should be able to look at it.

Make sure you've updated to the latest R11.

Can you share some footage ?

Would love to see how the 3:1 holds up

The way Grant Petty made it sound in that video from last year made it sound like its virtually identical looking...

Resolve 11.1.1 should read the files okay. Please share a DNG if you can.

Did you mean video from last week?

No, its a video thats been posted around recently...he talks about compressed RAW...seems to imply its not a huge sacrifice. I dono if what he's talking about in this video is exactly whats been put in the URSA but it sounds like it. That particular comment might of been more aimed at the lossless compressed RAW, whereas the 3:1 is slightly lossy...I might be getting confused.

< towards the end of this video i think he mentions it along the lines of "most people can't tell the difference" or something.

That video was from NAB 2013, URSA had yet to be announced.

He was talking about the pocket and 4k, which at the time was supposed to get a lossy compression. ( they both have lossless compressed RAW as we all know now. )

The new 3:1 codec with URSA is visually lossless a.k.a lossy. ( not lossless )

I think Shane is correct though about the very brief reference at NAB 2013 to 3:1 raw with lossy compression which at the time BMD said they had it, but decided not to use it as they went with mathematically compressed raw that is indistinguishable from uncompressed raw (since the expanded files are identical). It's interesting to they had considered their own 3:1 loss compressed raw at the time and have now released that for URSA. He's correct that most people in most situations would not be able to distinguish the 3:1 compressed raw from uncompressed raw when looking at the motion images it produces. Sure isolating a single frame, putting it under scopes you might find some differences, but in practice, it's a very welcome option to provide some additional record time on expensive media while still using 12-bit raw.
