Web Presenter 4k

The original Web Presenter can input 2 cameras but the current Web Presenters there is only one SDI input. Do I need additional equipment to input 2 or more cameras?

Yes, you would typically use a video switcher (such as one of the ATEM models) if you wanted to be able to switch between multiple video input sources. Or you could use a multi-channel video capture device (like the DeckLink Duo 2 or DeckLink Quad 2 cards) to take multiple video sources into a computer for use with software based video switching (OBS, Wirecast, Vmix, etc.).

The original Web Presenter (combined with a Smart Panel) could operate as a kind of simple 2-input video switcher, allowing to switch between 2 connected video inputs. And it also had USB webcam output to send the current live video source into a computer. It did not support sending both video inputs into a computer over USB at the same time though.

The newer Web Presenter HD and 4K models are purely single channel video streaming devices. They accept a single video input source and can stream it directly to the web over RTMP or can send the video into a computer over USB for use with other streaming software (like some of the options mentioned earlier).

Can you connect the original Web Presenter with 2 camera input to the Web Presenter 4k and then switch between 2 cameras?

You could feed 2 cameras into the original Web Presenter using it as a 2-input switcher, then take the program SDI output from the Web Presenter into a Web Presenter 4K for streaming purposes. That might allow you to do a simple 2 camera 4K live stream, I suppose.

Not sure what you are trying to achieve exactly though.

It is to utilise what I already have without spending on more equipments. A minimum of 2 camera controls might be sufficient for what I have in mind.

I heard the Web Presenter 4k can upsample 1080p signal to 4k but can it upsample 720p signal to 4k?
Likewise can it upsample 720p signal to 1080p?
