STUDIO USER MANUAL
Keystone Position
The Position parameters can be used to move the entire keystone surface left/right and up/down so as to achieve a
more accurate alignment with the surface that is being projected upon. Keystone position can be adjusted even
without any other keystone controls being changed, giving the impression of a linear translation of the overall Mbox
output.
Keystone Scale
The Scale parameter can be used to scale down the entire keystone surface so as to achieve a more accurate
alignment with the surface that is being projected upon. Keystone scale can be adjusted even without any other
keystone controls being changed, giving the impression of reducing the overall size of the Mbox output.
Keystone Rotation
The Rotation parameter can be used to rotate the entire keystone surface so as to achieve a more accurate alignment
with the surface that is being projected upon. Keystone rotation can be adjusted even without any other keystone
controls being changed, giving the impression of rotating the overall Mbox output.
Keystone Edge Blend Controls
The positions of the eight primary keystone controls create linear edges for the keystone surface. To better allow the
output of an Mbox server to be blended with the output of an adjacent server, each side of the keystone surface can
have a blend applied independently. The blend will be parallel to the corresponding edge of the keystone surface.
As noted in the previous Keystone Modes description, there are three blend curves for the Art-Net/sACN controlled
keystoning: Steep, Medium, and Shallow.

Layers: Texture + Object
Each of the 8 content layers incorporates both Texture (2D) and Object (3D) functionality. The Texture element
displays 2D elements such as still images and movies. The Object element displays 3D objects or digital gobos. The
combination of the Texture and Object elements make up the final composition of each layer.
CAUTION!
Even if you are not actively using 3D objects or digital gobos, there are object-related controls on each
layer that can affect a texture on that layer (e.g., X & Y Scale, Z Rotation).
Texture
In addition to texture selection, the Texture controls allow further manipulation of each layer. For the most part, the
Texture controls act in 2D space. Each layer can be colored individually; the position, aspect ratio, and scale can be
changed; the playback mode, rate, in/out points, and frame blending can be controlled; the transition type and timing
can be modified; and effects can be applied.
IMPORTANT! Mbox can transition from one texture to another on the same layer. This feature makes Mbox both
powerful and easy to use. The ability to transition on the same layer speeds up programming and can help in live
situations. A transition style (e.g., dissolves, wipes, bleeds) and a time for the Texture transition can be set on each
layer. If a layer’s transition time control is set above 0, Mbox will use the layer’s current transition mode to change
from one image to the next in the time designated.
