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:

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.
