This means Caspar can send different content to each output. Caspar also has the facility to output a key generated for a specific channel on another channel. Therefore the 2 independent outputs on the card can be a fill from caspar and a key from caspar. The card will receive 2 separate rgb frames, one for each output. The nature of the card means it was never designed for the 2 outputs to be in sync as it will always treat them as 2 independent feeds, therefore you can't rely on them being in sync.
This is not correct, I was mentioning the Decklink Duo having two channels, not the Decklink Studio. The Studio is a single channel. It can be used similar to the 4K with separate fill and key out, but ONLY IN SD. In HD there is only a single output. As of today most productions are made in HD I would not recoment buying such a card.

Can´t figure out how to use the Ultrastudio as two channels. It automatically do key+fill Operation. But this is, what most people (and I ;-) ) want.
Will give it a final test tomorrow.
Unfortunately we can't confirm this setting running here. Tested Windows 7 x64 on Bootcamp on a MacBook Pro with Ultrastudio 4K. Although it is possible to install drivers for Thunderbolt (included in Bootcamp) and Ultrastudio 4K (Blackmagic Desktop Video 9.8, Blackmagic DeckLink WDM Streaming), we didn't get any video output with CasparCG Server 2.0.4. CasparCG Server is listing "UltraStudio 4K 2" as device number "[1]".

Is the fact that CasparCG Server is listing the correct device prove for correct functionality?
Can anyone see wrong settings in the config file or within the images attached to this posting?

@TheYouth
Which driver did you use for the UltraStudio 4K? As far as we tested there is no driver automatically found in Windows. We decided to install the driver called "Blackmagic Driver" manually.

Anyone any ideas?
Thanks!

For the Ultra Studio 3D, I am using the most up to date version of CasparCG client and server. You must have Thunderbolt cable plugged in when computer is turned on. You cannot use BlackMagic current software and drivers. It must be the one I previously mentioned. It recognized the device and then I choose 2 Decklinks as my output. Splits the fill and key.... And AWESOME results. I just filmed an event with lower 3rds, tale of the tale and time clocks via CasparCG. It took me a while to find all the variables to make this work but it was worth it.

Re: Supported SDI and HDMI video cards

Guys, please have some patience with me. I have been searching and reading the forum and some things I just don't understand about the cards.

My setup: I want to connect a SDI out from a switcher to a decklinck and add graphics to the material for a live stream. So far no problem. I connect the SDI to a decklink 4k extreme and output through live media encoder...voila, right?

But in the overview I see I can only connect 1 connection. So if I also want to output to a big LCD through an SDI that is no longer possible with al the CasparCG graphics? So if I want that I need 2 cards? Could you explain that a little more for me, because I really need to order a card soon but still don't know what to buy.

Thanks in advance.

Re: Supported SDI and HDMI video cards

#69
The way you described it, (as far as I understand you) you come aut of the switcher with an SDI signal, into Decklink 4K out as SDI into a encoder. Now you would also like to send the same picture to a beamer. (SDI baemer?) What you need, in this configuration is a SDI distributor to split your SDI between the 4K and the encoder. I would buy a Mini Converter SDI Distributor: http://www.blackmagicdesign.com/product ... ers/models.

The other way would be, if your swtcher supports downstream keying (what switcher do you have?) Do send the graphics to the switcher for keying and split up (if the switcher has only one output) the PGM out of the switcher.

Re: Supported SDI and HDMI video cards

Erik,

No problem, we have lots of patience!

If you want to add the graphics AFTER the mixer, you need 1 input AND 1 output. As you can see in the table of video cards, in the column called Simultaneous connections per card the Decklink 4K Extreme has:
0 inputs and 1 output (SDI: fill + key, or HDMI: fill, or component: fill)
or
1 input (SDI: fill-only, or HDMI: fill, or component: fill) and 0 outputs

Your options are:
  • Use CasparCG Server with key+fill HD-SDI output through one video card (the Decklink 4K Extreme is the recommended card since it supports synchronized key and fill signals) and feed that into your mixer.
  • Use the SDI output from the mixer and feed it into a Decklink card in a CasparCG Server, have CasparCG Server overlay the graphics/videos on top of the input video and output that through another "device" (see the column Number of "devices" visible to CasparCG Server if you want to use a card with simultaneous inputs and outputs.)

You are right. He was complaining of only haveing one SDI out, but needing two. At least that was, what I understud.

Re: Supported SDI and HDMI video cards

Hi to everyone!
I just wonder if I could use caspar only as internal keying soft. I mean i can get the program signal in via decklink and send only one signal (program with graphics) to out. Therefore I could save costly inputs in my swither and not use one sdi for fill and one sdi for key. how do you think, does it make any sense?

Re: Supported SDI and HDMI video cards

#78
Hi,

yes, this is possible. But this will add a delay of about 7frames to your prg-out.
If this is not a proble, you can use it like this:

Camera --> Vision Mixer -> (prg. out) CasparCG Decklink/Bluefish input --> CasparCG Decklink/Bluefish output (prg. out)

The delay does not appear, if you use a Decklink 4K (or extreme 3D) in internal keyer mode. Only if you input your video as a layer inside Caspars mixer.

No, not as consumer, just as a simple output. There is a setting for internal keyer:

The card feeds the SDI input straight trough (without delay) and keys the graphics on top. This works only with the 4K, with the 3D and (only in SD) with the Decklink SDI.

That's why I always say: Boy go buy you a 4K, because then you have all the options...

Yes, and I prefer to have some control over whether I have the key activated or not. So, the person controlling the casparCG server will have the control.

But for cheap and simple workflows, this is a good option. And 1 frame of delay is kind of standard in digital video.
You won't find a system without delay ;-)

You want to do a picture in picture effect, right? Then it depends on the model of your ATEM. Some of them have DVE's inside, that gives you a PIP effect inside your vision mixer. If you need to do it in Caspar, a mini recorder will do. But be aware of 7 frames delay, you will either need to feed audio trough Caspar or delay it with an audio delay device.

Re: Supported SDI and HDMI video cards

thank you! not exactly just PIP. Atem can do it in very frustrating way. i need to put time video in the graphic shell. that is the way I gonna use caspar. Basically I can use atem USB 3.0 as input on caspar machine. I just need to change caspar XML file. But I never did it and this is too complicated for me..

Re: Supported SDI and HDMI video cards

#91
No, with the 4k, you can use casparCG at the end of your workflow as explained. No need for an extra input.
There are 3 general workflows possible with casparCG and video inputs:

1. The normal way with separate key+fill (needs one decklink 4k and one other sdi input):
SDI Input --> casparCG --> SDI outup via Decklink 4k as 2xSDI (1x FILL, 1x KEY) --> Vision Mixer
=> The vision mixer will composite the input from casparCG onto a background itself with the key and fill signal from casparCG

2. CasparCG as Keyer (needs 2x SDI cards, one for input, one for output):
SDI Input (prg.out of a mixer or a cam) --> CasparCG --> SDI Output
=> CasparCG plays and overlays everthing and only provides a new prg-out. This will add ~7frames of delay for processing.

3. CasparCG with Decklink 4k as keyer (Only the 4k Card is needed):
SDI Input to 4k Input (prg out or cam...) --> CasparCG --> SDI output of 4k card (prg out)
=> CasparCG plays all the overlays, the compostiting is done by the hardware keyer of the decklink 4k card.
This add ~1frame of delay and only works with the decklink 4k and 3d extrem cards in hd and decklink studio in sd)

Re: Supported SDI and HDMI video cards

#94
Just be sure I understand you:

You want to film the games clock and add the videostream as an input to overlay it over the second camera stream with the game like you do with the shown graphic?

Is this right?
So you need a typical PIP which you need an other decklink input for.

You would have a decklink 4k as output with fill and key which goes into your vision mixer and is used as DSK.
Then you have a decklink as input for the clocks video, which you would play on a channel and do all the scaling and cropping it. On an other layer, you can add the graphics as shown.

Is it that, what you want?

Re: Supported SDI and HDMI video cards

and by the way, about controlling the person who's making the graphics.. Well,
mixer prg out to - caspar prg with graphics back to - mixer (one input) - via aux to stream or whatever
So, you can give prorgam to graphic-operator and watching that program with the graphics back in your multiviewer.&
That's just for saving one input in mixer

I work with Erik (see this post: http://casparcg.com/forum/viewtopic.php ... 474#p13474 ) on a livestream setup with CasparCG for an event. The ultimate setup we want is in the attachment (image) with this post. For this year we don't need the output to a big LED screen yet.

We have bought a Decklink 4K Extreme an tried to use it to use CasparCG as output and loop this on internal output to FMLE. Unfortunately the Decklink card can be used by one software at a time, so we made a mistake there. We thought we could do the trick using one 4K Extreme card, if we didn't need the big screen.

Can you tell us what we need to get everything to work? Do you have any comments on our diagram? The video switcher will be supplied on the event, and we don't need the output to the big screen yet.

Thank you for your answer.

This part I do not understand. What do you want to play out from Caspar, in you schema you only have one output to the vision mixers "Media channel' whatever that is. What brand and type of mixer?

I would feed the LED Screen straight from the mixer, use a distributor like the Mini Converter SDI Distribution http://www.blackmagicdesign.com/product ... ers/models, if the mixer has not enough outputs. You probably will gain delay when you go via streaming PC.

Didi, thanks for your answer. You're probably right about the LED screen. We don't know the brand/type of the mixer yet.

We want to use CasparCG to put an overlay (logo, titles, etc.) on live video from the event mainstage and then stream it to YouTube. When there is no live performance on stage, we want to use CasparCG as a video playout server (with overlays), also on the same stream to YouTube.

Re: Supported SDI and HDMI video cards

Hello,

I'm in the "playing around with Caspar and it's clients" stage and I've been looking at the cheaper Blackmagic cards on ebay. From reading the supported cards spreadsheet, it looks like the 'mini-monitor" is not recommended. How about the Decklink SDI (US$130) or Decklink SDI 4k (US$240)? At the moment, I don't need sync'd key/fill outputs or even HD, just something that will give me a usable output for not too much cash. BlackMagic's web site is somewhat silent on which cards are supported by which drivers. The goal is to get at least SD-SDI with embedded audio. Could use HDMI but then I'd have to convert to SDI anyway. Thoughts on this?

Thanks,

z!
