Hi Jeremy, Hi Claire.

Haven't heard replies in the other forum since i posted in APRIL and requested an update in MAY.

As It's JULY and haven't heard an answer i rewrite in this new community in the hope to receive an answer to my simple request.

As i work with large broadcast companies we need to output 4K in SDI from Vahana VR, but at the moment this is not possible:

- Blackmagic DeckLink SDI 4K output only in 1080

- When will 4K output be implemented?

- Do even exists cards that enable 4K SDI output from Vahana?

Basically i need Vahana to work as a real time stitching box.

Without SDI output in 4K the software for us is just incomplete (besides the many bugs you're slowly removing).

Hi Brickbeard,

There are already a few options you can use to output 4K through SDI in Vahana VR (list of supported card: http://support.video-stitch.com/hc/en-us/articles/203656986-Supported-video-input-output-cards):
- Decklink 4K Extreme 12G
- Aja Corvid 88 (only Quad Link support, this is a beta feature)

In the past, we had issues with Decklink and 4K due to a bug in their drivers. Do you have the latest driver installed? Are you able to output 4K with that card and other 3rd party software?

Please note the SDI 4k is not officially supported as we don't have it in our office so we are not able to test it internally ourselves.

We will do our best to solve your issue anyhow but it might be out of our reach.

Best Regards,
Jeremy

Hey Jeremy,

here my answers:

- yes all drivers are up to date

- yes we are able to output 4K from that card, and from 3rd party/competitors apps

- as already stated in vahana the card works fine in all resolution up to 1080p, anything further just show a black screen.

If you don't officially support it please change your video that clearly show it working (with an atomos) and even explain how to set it up because it does give the impression that it is/was supported....https://youtu.be/nR0qD2ELInU

Thanks,

Hi Brickbeard,

I've just tested the Decklink Studio 4k (which was also not supporting 4k, only 1080p) with the latest Vahana VR version (v1.1.0 RC2) and the Decklink drivers v10.6.6. It outputs 4k successfully. Which means the SDI 4k might also be fixed but I will not be able to test it right away.

Are you testing on the RC2?

Thanks for raising that YouTube video, I will see what we can do to avoid that kind of miscommunication in the future. I also placed a purchase order for the Decklink SDI 4k, and, as soon as we receive it, I'll make sure we can reproduce this and solve it as soon as possible.

Best Regards,

Jeremy

Thank you Jeremy,

was testing on RC1, now on RC2 (i missed the email with the release) all seems to work; without sound but there is clearly written audio not supported and anyway that's not an issue.

Many, many thanks,

T

Hello, Videostitch.

We need to use notebook with Vahana VR for 4K SDI output.

Can we use Ultrastudio 4K via Thunderbolt to output 4K SDI ?

Hello Andy,

As of now the Ultrastudio 4K is not a supported output option.

You can see all supported options here :
