Live Streaming with Moxion Connect

Moxion Connect is a multi-purpose standalone app that you can use for live streaming from a macOS- or Windows-based computer that's connected to the internet. It can be used in combination with our Rooms to create live editorial reviews or color grading sessions (with HDR support).

This article will walk you through the steps necessary to get your computer connected to Moxion via Connect so you can get to work.

Adding a Stream Location / Creating a Live Asset

Open the Moxion Connect window and click Add Stream Location (+)

This will show a New Connection Code. Click the icon to Copy the code to the clipboard.

There are two possible destinations for a live stream from Moxion Connect: Streaming to a Room, or streaming to a Folder. 

Streaming to a Room

With Moxion Connect, you can now stream a Live asset directly into a Room. To do so, once inside the Room, click the "Live" pane icon ((●)), then click "Add Live Stream," and lastly, enter the code that you copied to the clipboard above.

Streaming to a Folder

You can also stream an asset into a folder, which can then viewed inside that folder, or brought into a Room. In the destination folder within Moxion, open Folder Settings > Live Assets (shown below) and click [Create Stream]

That will bring up a window where you'll need to enter some information to make the connection.

Source - choose Moxion Connect

Name - This will be the title of the asset when viewed in Moxion (eg. Live from Editorial)

Description - This is additional info for context within the Production (eg. Streaming from John's AVID machine)

Connection Code - This is where you'll paste in the code you generated in Moxion Connect

Once that's done, click Create and head back into Connect to see the new link that you established.

Congrats! 🎉

You've just set up a new Live connection between Moxion Connect and your Moxion production. This is reflected in the Moxion Connect application with either the name of the Room you've connected it to, or the Name you defined when creating the stream in the folder. 

Adding a Stream Source

Now that we have a Live connection established we can choose what content we want to stream to the platform. Click the name of the stream we want to adjust to open the Stream Source menu.

Select Stream Source

Displays: Share a full-screen capture of your Desktop (Screen Sharing)

Windows: Share a capture of a specific window on your Desktop (Screen Sharing)

NDI: Share an available NDI source on your network (click here for more info on configuring NDI)

DeckLink: Share the input of a BlackMagic DeckLink capture device (including SDI/HDMI models)

Once we select a source it will be the default source for this Live Asset, to Go Live and Start/Stop the stream click the Stream button next to the name (All Streams Live) or Individual Inputs (Ad Hoc stream activation)

Multiple Streams are supported from Multiple Inputs and can all be activated/deactivated individually

These all output to Moxion into the designated folder as individual/unique Live Assets that can be managed around Moxion in the same way as traditional/static assets. For more information on Working With Live Assets check Live Streaming - Moxion Guides

Stream Settings & Specifications

Once a stream is set up and available within Moxion Connect we can click the preview to open the Settings for this stream:

• Resolution - Choose from the Original resolution of your Source or scale your Output to various HD/SD resolutions in 16:9 aspect ratio. Maximum resolution that is supported is 1080p.
• Bitrate - Choose from Low (3000 kbps), Medium (5000 kbps), High (8000 kbps) and Very High (10000 kbps)
• Audio Reference Level (NDI-only) - The headroom that we apply when receiving the audio from the NDI source. This is applied when we convert the audio coming out of the NDI source (usually a floating point sample format) into a 16 bit interleaved format that we can transmit through Moxion in the final live stream.
• Stream Audio Offset - If your viewers are noticing a delay between Audio/Video we can adjust the audio offset in increments of +/- 50ms
• Local Audio Device - If your Audio is outputted entirely through NDi we can select a local Monitoring device to receive the audio.
• Color Profile - Choose from an available Color Profile. For more information see Color Profiles and HDR Live Streaming with Moxion Connect
• Delete Source - This removes the Source from Moxion Connect. This does NOT delete the connection with Moxion - a new source can be configured to stream to the same asset/location.
