I'm trying to capture two PTZ PTVL-ZCAM at 1080p60. According to a post on your site-Duo 2 Compatibility-that doesn't seem to work with the capture card I have now, the BlackMagic DeckLink Duo 2. Do you know of another dual input capture card that would work? I have to be able to do Nvidia GPU Direct to the GPU. 



the black magic Duo 2 will work with certain resolutions out of our cameras, but not with 1080p50, 60, or 59.94. if you are looking for a good capture card solution we suggest the cards made by magewell found HERE. these are very reliable devices at a reasonable price point.

Hi is there any update on when the PTZoptics cameras will work at 1080p50 on SDI with Black Magic cards.  I have other cameras that work and with BlackMagic being a big player it would be great to solve this.  I can make them work using HDMI to SDI converters but that is another thing to go wrong. 

Hi Leo,

We have done what we can to solve this issue through firmware updates. And it looks like there will not be a fix for this issue on the current G2 generation of cameras. 

At this point the cameras (not including ZCAMs) are capable of outputting some additional broadcast framerates which allow for more resolutions/framerates that will work with Blackmagic devices. But 1080p60, 50, and 59.94 still will not work over SDI with Blackmagic products. 


On the website and in the youtube video about compatibility between Atem TVS HD en PTZ Optics camera, is told/written dat by SDI you can connect with 1080p30. I have bought since yesterday the TVS HD, but does not connect on 1080p30 by SDI. What was the setting of the camera in that test?

Hello Henny,

If you are using one of the PTZ models try using the 1080p29.97 option instead. That would be dial position C. And make sure the ATEM's input video format is set to match.

(Be sure to reboot the camera after making changes to the System Select dial)

The Blackmagic hardware seems to handle the broadcast framerates better.


Thanks for your reply. After upgrading to the last firmware 63.04 > 63.11 is does work.




I've got several PTZ 30x and PT20x-ZCAMS working well on a BMD TVSHD set to 1080p, 29.97... However, I can't seem to get the one PTVL-ZCAM we have to work.  It connects and you can see the image perfectly through the switch just for about 30 second upon boot up, then it flickers out and never returns.  The camera is fine as it is seen via IP and SDI direct connect to a monitor perfectly.  Definitely an incompatibility with the switch.  Any suggestions????

Hi Michael,

For the Zcams, they cannot do the 29.97 or 59.94 framerates, so that does lead to some incompatibilities with the ATEMS and other Blackmagic pieces of hardware. You would have to use the PAL framerates of 25 or 50 or use a framerate converter to turn the 1080p30 from the camera into a 1080p29.97 to make this work. 

We like the Decimator MD HX, but others should work as well.
