Good evening. I open this discussion to share with you my experience with hdmi extenders.

I have come to the conclusion that there is something limits the use of the same with Vmix, or with the blackmagic design cards.

I've been using Vmix for three years, starting from the bottom. I started my first experiences with low quality acquisition cards and low performance PCs.

Over time I chose to use HDMI connections. I purchased a Decklink Minirecorder and recently an Intensity pro 4k.

Since we shoot football matches, we need to connect the cameras in points far from the pc, up to 100 meters away, so we need extender hdmi.

Today I can say that I was lucky, because the first extender I bought immediately worked, I say because the second purchase I can not find one that brings the signal to Vmix. Attention the extender work, because if I connect the output of a camera, to a monitor through the extender, I can see the image, while Vmix shows me only a beautiful blue. I tried several extenders but I always had a lot of difficulties.

Maybe I was wrong to choose the Hdmi, instead of an SDI, or maybe Vmix or Blackmagic acquisition cards have limits. Unfortunately on this forum I have not found exhaustive answers, and at the moment I do not know what route to take.

I would like to further improve the quality of the connections but I do not know how to move.

Thank you

I went a slightly different route by opting for a Magewell Quad SDI Input card. At the time, all of my cameras were HDMI. For distances up to 300 ft, I use HDMI-SDI Converters and high quality Belden or Canare RG59 coax. You could add some SDI-HDMI converters on the other end as well for your capture card. I use cheap chinese converters and haven't had a problem with them. But now with the Blackmagic micro converters being less than $50 each, it doesn't really make sense to take a chance on the cheap ones anymore.

Good luck.

In reference to converters, I think what Kelvin posted is useful. Whatever works for you is the right one. The Blackmagic micro converters are priced at the same level as the generic ones. I use AJA HA5 Plus units, but there are less expensive brands that will give you good performance.

And I'd agree with Kelvin on using quality cables. Though it's stiff, Belden 1694A works well at longer distances.

I tried to use Blackmagic mini Recorder in combination with Marmitek megaview 66 extender, and all I get is a black screen. Extender works perfectly well with Elgato HD60 s+ capture device.
Does anyone know why I can't get the image with Blackmagic?
Anyone has experience in pairing those successfully?
Thanks!

Thanks Xavier for response.
I will stick to elgato than, it didn't give any issues so far.
Fiber is a good tip, but it does go beyond the budget at the moment.
