HDCP problem with Sony Camcorder

Hi everyone
I have two AverTV capture HD card (HDMI input). It works just fine with Sony handycam, I have troubles with Sony EX1. It has only SDI output. So, I bought an SDI to HDMI converter. It works just fine on TV, but when I try to connect to vMix, it only gives me HDCP. (This kind of connection worls also Ok with the original Avermedia program).
I tried with another solution. EX1 via SDI cable to HDMI converter, to input of my monitor, then with HDMI cable from output of the monitor to capture card. Well, I solved the HDCP problem, but now my picture in vMix in blinking.
Any idea?
Thanks.

Whoa, you have a lot going on there. I've found that vmix needs the capture card to lock onto it's source's exact frame rate. If you're set for 30fps, but it's sending otu 29fps, you're going to get dropped/blank frames from time to time. It might be that the FPS your camera is putting out doesn't match with one of the frame rates that your SDI->HDMI converter works. I know you said that it works on your TV, but remember that your TV is a consumer device that has 'anti-flicker' tech built into it... so it's not a good ruler to measure the converter's performance.
NOTE: the SDI->HDMI->Monitor->HDMI solution will never get you where you want to be. There are too many conversions going on there to ever be reliable enough for a broadcast that you're selling.

Thanks, usefull reply, anyway, how do you explain the fact, that I don't get a picture in vMix at all (no dropped/blank frames, just HDCP title), but I get a perfect picture in AVerMedia TV Software with same settings: Ex1 camcorder -> SDI to HDMI-> Avermeria capture card.

Thought I would add some notes here as we seem to get a lot of emails about this.
For the record the HDCP message is not generated by vMix, it is coming from the AverMedia driver.
The usual reason is that a HDCP protected source is plugged in, but in some cases it means the
Resolution and Frame Rate in vMix are not set to exactly match the source camera.
This is also confused by the fact that the AverMedia application will show HDCP video but prevent other applications from doing so.
Hope this helps.
Regards,
Martin

i have some experience in this.
avermedia may show picture as long as you don't try to record anything, as soon as you're trying to record (and that's probably the way vmix 'connects' to the driver) the hdcp protection kicks in as it's supposed to do.
If martins tip doesn't help, there is something called an hdcp stripper, but same arguments as posted before should make you not want to use those.
(i personally find it hard to believe a converter would add hdcp, so i think martins tip will work)

Well, actually I found, that a converter adds HDCP. I have tried to record a footage in Avermeria program, and I got a notificiation that it was not possible because of the protection. Anyway, now I know, where the real problem is.

I have the same problem . I just installed a avermedia C727. It works perfectly if I plug the HDMI cable directly . But I need to connect a camera to at least 60 meters , and I purchased a HDMI extender, but adds HDCP. Did I say something stupid , I wonder if you could put a flag for disabling the protocol from VMix, in INPUT Camera

If you have someone that have for example BlackMagicDesign miniRecorder or Intensity Pro capture cards try with them, I think there will be no problem. I was thinking to buy Avermedia too few days ago but I found posts and reactions on internet of the people who were very angry If you read description on official site you can read this: *Capturing HD content with HDCP (High-Bandwidth Digital Content Protection) is not supported. p.s. I already have BMD Intensity pro and I am very satisfied, and now I am thinking to buy MiniRecorder, the price is bigger but in the end it's worth it

In fact, I made a big mistake to buy AVerMedia ......
with the same money I would soon have a Blackmagic Design Intensity Pro 4K .... for now I have to fall back on a splitter :-(
Grazie!

I use an Aver Media C127 capture card routinely. I bought it to capture the output of various Android devices (Nexus Series) which include HDCP on the output. The only way around this that I have found is to split the output, sending on leg to a monitor and the other to the C127. In that way the monitor satisfies the HDCP handshake, so vMix sees the stream. In my experience vMix will not see the stream at all unless HDCP is satisfied. It only sees a large "HDCP" message, which I believe originates in the Aver Media driver. The Aver Media card has been much more reliable than the BMD Intensity Pro I used previously. Further, I doubt that anything can be done in vMix to impact this situation. HDCP is implemented in hardware on the convertor/capture devices. I don't believe that software control is permitted.

Michael and if I connect only one output to the card ? Does it work?

I have a system with two (2) DarkCrystal HD Capture SDK II (C729). Using a Sony camcorder and connecting with a 15' HDMI cable I get no issues. Then I use my HDMI extender with 200' of CAT6E cable to connect to the AverMedia card. There is no issue. Everything works as it does on actual live events. If the converter or HDMI extender causes an HDCP issue, there are others devices of those types that won't.

Connect the capture card last

Connect the capture card last ok , but after connecting the cable to the card , I can disconnect the monitor ?
