In our modern digital lives, we have an endless number of ways we use our computers, including using them to produce video. We may want to send full-screen output as video to a switcher or recorder to make training or demonstration videos. We may want to send just the output of one program as a video source like a dedicated text or graphics program specifically for broadcast production, or it could be a program used daily for common business or personal tasks.
Many broadcast production applications have adopted NewTek’s Network Device Interface (NDI) and are able to send their output to the network where any NDI-enabled production system can receive it. Products and applications that don’t yet include IP workflows can do so by using NewTek NDI Scan Converter, one of the applications in the free NewTek NDI Tools Pack. 
The NewTek NDI Tools Pack is a free download: NewTek NDI Tools Pack Download Page (registration required).
