3 Previews

MADRIX 5 features 3 main Previews.
That means that you can have a look at your effects and visuals before they are displayed on your LED installation. These are live previews and they show everything in real time.

▪Preview Deck A / Preview Deck B - Located to the upper left and to the upper right of the user interface. They represent the two preview windows for the 2 Effect Pipelines.

▪Preview Output - Is located in the middle. This window is a preview of the actual data output that is sent to your interfaces/LEDs.

▪A MADRIX 5 Preview is a technical representation of your installation. You will see the individual pixels/voxels and how the effects will look on your LEDs, but not realistic renderings of your projects you may know from visualizers.

As explained earlier, you can use MADRIX 5 to control 2D and/or 3D projects. [Learn more »2D Or 3D [X, Y, Z]]
The 3 Previews support a 2D mode and a 3D mode to adequately represent your LED installation. In this way, they are an important part of your workflow when working with your project.

▪Go to the menu Previews > Preview Deck A/Deck B/Output > 2D Mode to choose 2D mode for the left/right/middle Preview.

▪Go to the menu Previews > Preview Deck A/Deck B/Output > 3D Mode to choose 3D mode for the left/right/middle Preview.

You can use the Previews in 3D Mode, even if your virtual LED matrix is only 2D.
And you can use the Previews in 2D Mode, even if your virtual LED matrix is in 3D.

You have different options of working with each Preview. It depends on 2D mode or 3D mode which options are available to you.

▪Left Mouse Click And Hold And Move - Click with your left mouse button on a Preview, continue to hold, and move your mouse in order to move and relocate the Preview.

▪Use Master - Applies the Master to the Preview Output. Deactivate it if the middle Preview should not reflect the main brightness and instead is always shown at full intensity.

▪Use Fixture Groups Intensity - Applies the Fixture Groups to the Preview Output. Deactivate it if the middle Preview should not reflect the group brightness values and instead is always shown at full intensity.

▪Show Pivot Element - Displays a helpful icon for visual guidance. Three arrows are always shown at position X=0, Y=0, Z=0 [not matter if the Preview is rotated]. The X-axis is red [horizontal; width], the Y-axis is green [vertical; height], and the Z-axis is blue [level; depth].

▪Default View - Choose your point of view and the default view for this Preview.

▪Restore Default View - Resets the Preview to its Default View. This removes any changes, such as zoom or relocation.

▪Disable - Deactivates a Preview. This can be helpful to save computer resources and increase performance. Especially, 3D mode requires a lot of computer performance.

The Previews mainly show your effects and visuals. Depending on different settings and requirements they convey additional information.
Note: The different scenarios explained below can apply at the same time.

▪Right Mouse Click on a Preview > Preview Settings... - Opens further settings for the associated preview. You can change the settings for each preview individually.

▪The following settings only apply when the preview is set to 2D Mode, but your Patch includes fixtures on multiple Z-layers [Z > 1]:

▪You can set up the Slice Order. Choose from Left To Right, Right To Left, Top To Bottom, or Bottom To Top

▪In this way, you can define, for example, how the different Z-layers are shown in the preview. This can be especially useful, when using Z-layers for different content and not necessarily 3D effects.

	Left To Right	Right To Left	Top To Bottom	Bottom To Top
X-Slices
Y-Slices
Z-Slices	[Default]

▪Note:
- You may change the Preview Settings when in Operator more or switch to Operator mode when the Preview Settings are still open.

▪Clear Message - Only the Preview Output offers this option. MADRIX 5 may show information or error messages in the Preview Output.
- X - Discards any messages that MADRIX 5 shows. The messages will not be displayed anymore.
- Such a message could look like this:

When controlling LED lighting, the intensity of the light output makes up a large factor of the light design. The Previews will represent your intensity settings.
There are many ways how to control the intensity in MADRIX 5. The main examples are:

Master Set To 255	Master Set To 127	Master Set To 0 / Blackout

One of the main features of MADRIX 5 is that it renders visuals and effects live in real time. Regarding the overall performance, you can define a specific setting in the Options that will also influence the Previews. Depending on your settings, MADRIX 5 will include all voxels in the rendering process or only the ones that are patched.

Included Voxels: All	Included Voxels: Patched Only

When letting MADRIX 5 render all voxels, you can further decide how the Previews work. Voxels that are used [a fixture is set up at this position] are displayed brighter than voxels without LED fixtures. Compared to this, MADRIX 5 offers two choices in order to show or hide voxels that are not used. This will influence all 3 Previews. Positions without fixtures will be dark gray or they will not be shown and set to black.

Note: The Patch Mask will only fully apply, when your performance settings include all voxels, as explained above. If your performance options are set to only include patched voxels, the voxels will always be shown opaque. Changing the Patch Mask setting will not influence the Previews anymore.

Note: In demo mode, Patch Mask > Transparent is always automatically enabled and this setting cannot be changed in order to make sure that you see your effects and fixtures when not having a MADRIX KEY connected.

▪Or go to the menu Previews > Preview Output > Patch Mask > Transparent/Opaque

Patch Mask: Transparent	Patch Mask: Opaque

The Previews will indicate if you are using a higher output [as set by the virtual LED matrix in the Matrix Generator or Patch Editor] than your MADRIX 5 License provides. Unlicensed areas will be shown darker.

Select Help > MADRIX KEY > License... to check your MADRIX 5 License and product serial numbers.

Output Fully Covered By License	Output Not Fully Covered By License

When setting up an individual Patch in the Patch Editor, there might be areas where no fixtures are located according to your LED installation. These areas without any fixtures will automatically be displayed darker to indicate that this area is not in use.

The 3 Preview windows explained above are technical representations of the effects MADRIX 5 creates for you. But they are not pixel-perfect outputs.
DVI is another way to work with LED products which requires such a correctly sized output. To use DVI, MADRIX 5 offers other options.

DVI output allows you to easily control large LED pixel walls or use screen-capturing, for example.

If the Previews show this error message, it means that there is a problem with the graphics card of the computer:

▪The driver of the graphics card for the Windows operating system might be outdated.

▪Check if your computer's graphics card supports OpenGL 2.1. If it is not supported, your computer/the graphics card does not meet the minimum requirements of MADRIX 5. Please upgrade to a newer graphics card, which supports OpenGL 2.1.

▪Download and install the latest driver version for your graphics card in order to update the driver. [You might need to restart the computer afterwards.]
