NDI Workflow I How to Prepare and Setup NDI:

 

If you are new to setup Multicast, please also visit Article to: How to Multicast

 

Hardware: 

You´ll need a Switch which is Multicast capable. 

 

Prepare your network settings. Make sure that all your machines are in the same IP range.

NDI itself works generally as broadcast, but anytime when you receive a NDI stream, by default NDI creates then an unicast stream for you. 

 

Example: You receive a 1080p Stream via Pixera for your Output, you will have a downstream from about 140Mbit /s

If you activate also the preview in Pixera for this NDI stream, NDI has then to create a new stream, because the output engine and the preview engine are different engines. 

So now you have then a bandwith load from about 280 Mbit /s 

If you do this on three machines, you will then have a bandwith load from about 800 Mbit /s because of all the Unicast Streams.

 


 

 

To give you an idea how many bandwith you need for different resolutions:

 

 (+-10%)

720p:  80mbit

1080p: 130mbit
1440p: 180mbit

2160p: 300Mbit

 

SETUP MULTICAST FROM SCRATCH:

 

We recommend to use Multicast as Setting NDI. That means that NDI or Pixera creates than one single stream, and the multicast capable switch does then the rest for you. They duplicate the streams then to the ports where you like to spread out the NDI signal.

 

 

 

 

STEP BY STEP:

 

Open up the NDI Tools and get into the Access Manager.

 

 

 

 

Go to advanced, and drop down the multicast menu. Check the IP box. From now your NDI is set up to multicast. 

The IP adress range is a standard multicast range. If you do more multicast streams from different machines, make sure that you change the IP address. 239.255.0.10 as example.

 

 

If you have Pixera open right now, you have to do a restart that your changes are than active in Pixera. 

 


 

 

SETUP THE OUTPUT STREAM IN PIXERA:

 

Go into the Mapping Tab / Live and Dropdown your Local Machine. 

 

Here you will then find NDI.

Two ways to add a new stream. Right Mouse Click - Add Output Stream or on the right side in the Inspector.

Multiple NDI Output Streams are of course possible.

 

 

 

Once you have added the NDI Output Stream, you have then some options in the Inspector:

 

 

 


 

NDI INPUT / HOW TO RECEIVE A NDI STREAM:

 

A NDI Input Stream is to handle like a typical Live Input Cam

You will find the Live Input Resource in Compositing / Resources / Live Input 

 

 

 

Choose then your Live Input Resource in the Inspector and go to the NDI Stream

If you like to see your NDI Stream also in the Preview, make sure you check the Box "Show in Preview" below.
