Wirecast is generally ONVIF compatible. Are there specific ONVIF 2.4.x features you'd like to see implemented? Development consideration can be impacted by user input so please do request specific features you're seeing in 2.4.x.

Really? With the same ability to call up shots like the PTZ Optics camera.  I see this in the user guide:

The PTZ Controller enables you to control PTZOptics brand cameras. This feature is implemented using the VISCA-over-IP protocol, an IP-based protocol which sends specific camera control commands to the camera to change Pan, Tilt, Zoom, Focus, Exposure, and White Balance.

I don’t understand what is meant by generally.  Can Wirecast control an Amcreast PTZ camera whose controller protocol is ONVIF?  If so, how?

Kit Kinchen Wirecast can only control (move camera) PTZOptics at the moment but they may consider adding other cameras.

Currently ONVIF support is basically auto detection in Wirecast.

Please do make the feature request and mention ONVIF 2.4.x. In case the developers have to prioritize camera development mention Amcrest specifically.
Wirecast Feature Request

Do read this link

Amcrest
In the web stream configuration dialogue box, enter the following:

Protocol: RTSP
Stream Options: Auto-Detect
Format Options: Auto-Detect
URI: rtsp://(IP address, which you can obtain from the Amcrest IP Config application):554/cam/realmonitor?channel=1&subtype=0
Stream Authentication: Enter Username and Password (by default this will be username: admin and password: admin)
Once you click the connect button, you should see video unless the camera and your computer are not connected to the same local area network.

The issue is compatibility that I’m referring to.

Kit Kinchen Wirecast should recognize the IP cameras using ONVIF. It would not have camera controls though.

Should? Recognize?  Does Wirecast have incorporated ONVIF compatibility? The point of this conversation is to request control other PTZ cameras within Wirecast. 

Kit Kinchen Wirecast supports ONVIF camera recognition and input. It doesn't include PTZ camera controls.
