OSX NDI Connect NDI to SDI/HDMI
NDI Outlet for OSX allows you to output NDI IP Video streams to SDI and HDMI through your BlackMagic Design video interface. Where the NDI Source contains Alpha and the BMD device supports Fill and Key you will also be able to output fill and key.
If you are concerned about compatibility, try the test demo version of NDI Outlet, which allows testing, but inserts a watermark into the SDI stream as a demo limitation.
Note that due to app store sandboxing restrictions, NDI Outlet is not currently compatible with NDI | HX devices.
