To be able to play out a video on LED Pixel or for example on LED Tubes or LED stripes, Pixera offers the possibility to play out a screen via Artnet.
This converts the color information of the individual pixels into color values and assigns them to an Artnet universe. 

This is usually called Artnet Mapping or Artnet Pixel Mapping.

The workflow is shown in the video below:

Art-Net Output Mapping - Workflow

First, an Art-Net output stream needs to be created. In the Live system (Mapping → live), this can be done by right-clicking on Art-Net and selecting “Add Output Stream” or in the Inspector by selecting Art-Net and choosing “Add Art-Net / sACN Output Stream”.

After expanding Art-Net in the Live system, the newly created Art-Net output stream will be visible. This output stream needs to be assigned to a screen.

To perform the mapping, dive into the current screen by clicking the following icon.

Next, a new feed needs to be created by clicking the “+” symbol. The size of a feed can be adjusted in the Inspector. Additional feeds can be generated using the Auto Transform Editor, where the number of feeds can be set at the top of the editor. Furthermore, X and Y values can be entered to set the start and end points.

After assigning an Art-Net mapping, the destination size needs to be adjusted. By default, the destination size is set to 1×1 pixel for safety reasons. With a FullHD or 4K screen and accidental activation of the output, the entire network would be flooded with Art-Net data.

Below in the Auto Transform Editor, the DMX settings can be configured, including Address, Net, Universe, Sub-Net, Footprint, and Offset. The footprint is always calculated as the number of pixels multiplied by three, since each pixel consists of an RGB signal.

Switching the DMX settings from Auto to Manual provides additional configuration options for Art-Net. In manual mode, the start and end values for Address, Net, Universe, and Sub-Net can be defined individually, allowing precise control over the DMX output mapping.

The same options available in the Auto Transform Editor can also be found in the Inspector. The system automatically patches the stripes into consecutive DMX universes and subnets.

To check if the ArtNet output stream is working, the ArtNetominator can be used. 

Fixture Setup

Here you can define the fixtures to which the signal is sent. Below, you can see the footprint of the channels with the respective setting and the color assignment.

Export

This will export the current selection in a JSON format

Import

Allows to import a JSON file with the previously defined settings.

Start Pixel

This defines where the first pixel starts for the current mapping

Addressing Direction

Define in which direction the pixel assignment is done

Layout

This allows to define the format of the fixture, it is possible to add more than one, it is mostly intended for control channels, which allow to define a fixed value, for example a dimmer channel

Stride

Defines the number of channels used per pixel.

Adjust this value when working with different color modes.

Example (RGB): Increase the stride if you need to include additional channels per fixture. Extra channels will remain unused (empty).

Example (RGBW): If you do not wish to set the W channel, reduce the stride accordingly.

Shift

Moves the color channels within each pixel by the specified amount.

A shift of 1 moves the R channel one step forward (e.g., from position 1 to 2) without overwriting the next pixel.

Value

Displays as grayed out for standard color channels.

When additional control channels are added (e.g., a dimmer channel), you can enter a value for that channel.

Example: Set a dimmer channel to 255 for maximum brightness.

Note: Adding more than one color channel is technically possible, but not recommended.
 

Common Mistakes

Destination Size

Behaviour: Only one Pixel visible on Output

Immediately after assigning an Artnet mapping, the destination size is set to 1x1 pixel. This is done for safety reasons, as with a 1920x1080 screen and accidental activation of the output, the entire network would be flooded with Artnet. With RGB, that would be 6 220 800 channels.

To resolve this, please set your Destination Size correctly or “Lock to Source Size”

License and Test pattern

Behavior: White flickering or no change of Pixels on the Output

It can easily be overlooked that Artnet pixel mapping also requires an output license. If it is used beyond the licensed outputs, the watermark will also be displayed on the Artnet mapping, which manifests itself as white flickering or pure white on the Artnet Channels.

This can be checked in the On-Screen Statistic 

Test pattern

Behavior: No change of Pixels on the Output

It can also happen that the test pattern is activated, and you only see static values on the Artnet channels.
