App Description

NDI ScreenCapture HX broadcasts your Mac's desktop or application windows over IP Video using the lower data rate NDI HX2 protocol which makes operation over WIFI smooth and with low latency.

You can select to either broadcast an entire screen, a single window of any application or a cropped region of interest, to any NDI HX2 compatible receiver.

The NDI HX2 stream is high quality, but with a manageable HX2 data rate, Selectable as 1280x720, 1920x1080 full HD or scaled to the window size, and runs at full frame rate for smooth display.

Audio is also supported. Visit the support site at http://sienna.tv/ndi for instructions on setting up your system sound to allow broadcasting of your computer's sound output (rather than a sound input device).

Note: Turn on the "Auto Refresh" checkbox to track window changes live - for example when taking an app fullscreen or starting a powerpoint presentation. Frame rate depends on source resolution, and image content, and will vary.
NB: This app is not designed for streaming live video at full frame rate or things like Video Gameplay. It is primarily designed for business presentations or sharing webpage content via NDI.

Supports Intel and Apple Silicon Macs.
