Does anyone know what the status of fill/key support on the Decklink 8k pro is? We will most likely skip directly from SD-WS to 4k after we upgrade our lighting. Would this card allow 4k 60p key/fill output? It looks like a 4k version of the duo 2…
I have tried a 8K pro card with CasparCG 2.1.0 in simple 1080i50 mode and I did not find a way to get a key signal out of it, no matter what settings I try in config or desktop video. Dual-link 4444 output is not an option, I don’t even have a monitor that accepts it.
The 4K pro card I originally wanted does get key out, but this card is discontinued and replaced by the 8K pro.
I hope Blackmagic fixes the key-out issue, or those 8K cards will be pretty useless for me.
I’ve recently put together a casparcg with the 8k pro, and fill/key with 1080i is no problem.
Don’t know about 4k though.
Can you post your casparcg.config file here? But your monitor is able to display a normal 1080i50, right?
Strange, but today I really got the key signal out of the 8K card. Maybe it just needed one more cold reboot.
Sure I can monitor 1080i50 and even 1080p50, but none of those multi-link formats or beyond 3G SDI.
The relevant part of my config is this:
<channels> <channel> <video-mode>1080i5000</video-mode> <straight-alpha-output>false</straight-alpha-output> <channel-layout>stereo</channel-layout> <consumers> <decklink> <device>1</device> <embedded-audio>true</embedded-audio> <latency>normal</latency> <keyer>external</keyer> <key-only>false</key-only> <buffer-depth>3</buffer-depth> </decklink> </consumers> </channel> </channels>
Mine adds one line, the custom-allocator. To be honest, I don’t know what it does:
<channels> <channel> <video-mode>1080i5000</video-mode> <straight-alpha-output>false</straight-alpha-output> <consumers> <decklink> <device>1</device> <embedded-audio>true</embedded-audio> <channel-layout>stereo</channel-layout> <latency>normal</latency> <keyer>external</keyer> <key-only>false</key-only> <buffer-depth>3</buffer-depth> <custom-allocator>true</custom-allocator> </decklink> </consumers> </channel>
So does this card basically function like a 4K version of the Duo 2? Have any of you got 6G or 12G SDI key/fill out working? From the specs, it looks like it could do that, but it is hard to get a concrete answer.
The configurations most interesting to me are.
12G SDI Key/Fill out on connectors 1 and 2.
12G SDI input on 3
12G SDI input on 4
or 4 seperate 12G input channels. Could either of you post some screenshots of the desktop video utility config options for this card?
Sorry for the missunderstanding, when I said „Mine“ I was refering my config and not my Decklink 8K. Alas I do not own one, but would also want to know, if it can output fill & key in 1080p50 and 2160p50, as I am also thinking about buying one.
i have one of these cards in a server on a tour.
we are back out next week. and i can check to see if it will do a key and fill pair in 2k
i don’t use it that way, but i can test it for you. all so i think in will have to test it at i5994 as i dont think i have any thing that will take a pal fill and key pare. i do have some Barco image pros that will take the signal. how ever i will not be able to see if they are in sync.
jyeomans, I am in 59.94 land also, so that test will be useful for me. You might be able to test even higher resolutions if the card will support a key/fill output and two inputs.
Here is a testing method I would try:
Configure 3 casparcg channels. 1 key/fill channel with decklink output and two channels with decklink input and screen consumer outputs.
I would try outputting a simple pattern key/fill to output 1 in your native resolution and imputing it on port 3 and 4 to a screen consumer. With the quad 2, there are some port configuration and indexing oddities to be ware of that might apply to this card also.
Once you have a key/fill pair with a simple graphic with alpha going out ports 1,2 and in to two channels with screen consumers on ports 3 and 4, then increase the resolution up to 2160p to see if it works. This resolution increase could be done incrementally if going direct doesn’t work. This way you don’t need an actual 4k device to view the signal.
I look forward to seeing what test results you come up with.
Would be nice to know if it works in 4K Thanks for willing to test this for us. If it works in 59.94 fps it sure will also in 50 fps.
i Am sorry
the server that i thought had an 8k decklink card in it
does not. it has an quad 2.
i thought it had an decklink 8k as it was the newest and we talked about using that card.
Hahaha, what a pitty. Never mind! Thanks for posting back.
Hi everyone, I recently tested my machine with a Decklink 8k Pro. It works in 2160p50 incl. key output. The config of channel 1 is identical to my Duo2. Key output is on connector 2 on the 8k Pro. BUT there are no additional output channels possible as the 8k Pro is only one Decklink device to the system. If the card is set to In & Out Mode via BM Software, connector 3 can be use as an input but no more outputs possible.
I also mentioned that e.g. the Transform, Anchor Point and Distort Tools are not working in 2160p (V2.2.0).
Thanks for testing and posting back. That is good to know.
Originally the DeckLink 8K Pro was only a single channel card (similar to the DeckLink 4K Pro) with the multiple connectors only used for dual-link or quad-link SDI input and output.
As of a firmware update included with Desktop Video 11.0 in March, the DeckLink 8K Pro is now like a 4K version of the DeckLink Duo 2. Each of the 4 SDI connectors can be independently assigned as inputs or outputs (so you could have four 4K inputs, four 4K outputs, or two in/two out).
When setup for keying, the DeckLink 8K Pro is capable of outputting two independent fill and key signals simultaneously. Here is the link to the announcement from Blackmagic:
That is awesome! I had suspected the card was capable of that, but didn’t have evidence the firmware was set up to allow it. This might be why BMD had such a hard time confirming exactly what functionality this card was meant to have back when I called them about it…
Does anyone have a working config for two fill & key using the 8K pro? I’m trying to install one (currently working in 1080i50) and not having much luck getting anything out of it in either 4 independent channels (and trying to get the external_separate_device to work - keep getting an error that it cannot set up a fill output on channel 2 which I had specified as key only) or just a single channel with key (output 2, which I assume would be the fill, turns itself off for some reason).
Relevant section from my config (in 4 channel mode):
<consumers> <decklink> <device>1</device> <embedded-audio>true</embedded-audio> <keyer>external_separate_device</keyer> <key-device>2</key-device> <key-only>false</key-only> </decklink> <decklink> <device>2</device> <embedded-audio>true</embedded-audio> <key-only>true</key-only> </decklink> <decklink> <device>3</device> <embedded-audio>true</embedded-audio> <keyer>external_separate_device</keyer> <key-device>4</key-device> <key-only>false</key-only> </decklink> <decklink> <device>4</device> <embedded-audio>true</embedded-audio> <key-only>true</key-only> </decklink> </consumers>
I have a DeckLink 8k Pro fully functional, double channel fill+key
for me the trick was in the blackmagic settings: 1ºin+2ºout and 3ºin+4ºout
in this way the f+k are linked together and perfectly in sync
I tried only in 1080@50i, I don’t have any way to test higher resolution at the moment
would you mind posting your config file?
