DeckLink Quad HDMI Recorder Chroma Subsampling

PostFri Dec 03, 2021 10:25 am

Hello everybody!

I need a frame grabber with the following capabilities:

2160p60 and RGB 4:4:4. 10 or 12 bit color depth is not mandatory, but a definite plus.
Can anyone tell me, if a DeckLink Quad HDMI Recorder can do this?

If not: what other products do?

Also: does anyone know, what the minimum specs for the host system would be?
Quite a beefy one I figure...

Gretings and thanks in advance,
John

John, you’ll likely get more responses if you post this in the Live Production forum.

According to tech specs, DeckLink 4K Extreme 12G can do this. I tried in 2016 and could only get YUV 4:4:4, but I haven't tried it since.

DeckLink Quad HDMI Recorder can't above 2160p30.

Thank you very much to both of you for your replies!

I came to the conclusion that my Systems can't handle a 2160p/60 stream yet. Since new hardware isn't exactly cheap these days I bought this card here:

Intensity Pro 4K

I am very satisfied with this product!

My advice to Blackmagicdesign: Why don't you market this one to all the youtubers out there? There is certainly a market for an inexpensive frame grabber like this and your product is superior to those offered by Elgato and Avermedia.

Greetings, John
