Camera input video with HDMI extender does not work????

HDMI Extenders vary so much in quality, and some can be very fussy about what kind of Ethernet cable you use.
Since the setup works going from laptop to projector, and the camera works with the capture card when connected directly I'm guessing there's something about the signal that your camera sends that gets lost in translation.

What's the extender make and model? And those of your capture card and the camera that you're using? What's the signal you're sending? (1080? 720? VGA? Progressive or Interlaced?)

Does your camera have SDI output? In which case that might work better with an SDI cable and an SDI -> HDMI converter to the capture card.

Hi guys,

Thank you for your comments.

So I am using a Sony AII and I am outputting 1080p 24p, My capture card is a Magewell USB Capture HDMI Gen2. And the extender is this one

Definitely not the best in the market.

So the cable is a cat6 and definitely seems to be the issue but even though I researched online I could not find anybody talking about a similar issue.

Unfortunately, I don't have an sdi out in the camera.

Do you have any suggestion about some testing I could do? I bought the extender in a shop and I was thinking to try with an sdi extender but I don't know how to test it considering there is no output in the camera.

Thanks and sorry for the late reply

@elena If you want to start using SDI, you will want to pick up and HDMI to SDI converter and then an SDI to HDMI converter, or an SDI capture card depending on the need / setup. We use the BlackMagic converters and capture cards, but there are many options. The BMD ones can be picky depending on the software they need to work with.

Hei Andy, Thank you for your advice.

Do you think I can still use my Magewell capture card with Blackmagic HDMI to SDI and SDI to HDMI? If not, do you have any recommendation for a fairly good alternative for the HDMI to SDI?

I don't really want to buy a new capture card and also this one I have is really super reliable.

I am sorry but I don't know what BMD means?

Thanks

Changing the cable will be your cheapest option.
All Cat6 cable is not the same.
I try and use FTP cable instead of UTP.
This is what I'm currently using and I have no problems with it at all using Extron and Kramer HDMI extenders. The Kramer is particularly fussy.

So that would be my first thing to try.

When Andy says BMD that's short of Blackmagic Design.

@mark_m

Many thanks. I will check out what's the cable I am using and test an FTP first.

Yeah I am not a big fan of BMD so, I will check out other options before to test SDI.

I will keep you guys posted if I manage to sort things out.

Thanks

Are you sure, the extender can handle 24p? It isn't listed in the specs, at least not on the page you linked.
Why are you using it anyway? I't will surely cause you some trouble, if not your whole setup is going that way.
You'll propably be better off with 25, 30, 50 or 60 (it seems the A II does only do 50 and 60 in 1080p/i, beside 24p. But 1080/50i, 60i could be considered 25p, 30p.)
Besides that, all the devices in chain should do the same!

@elena

Hi, you’ve probably tried this already: hook up a monitor at the end of the chain instead of the capture card. Did that give you an image?

cheers

@dillthekraut

Oh I actually didn't think about it. I will try it out. Thanks

@gvanb

Actually, I didn't. I will do so, Thanks
