EFFECTS AND TRANSITIONS
Effects and Transitions with Additional Input Files
Effects and transitions that require additional image input files will use numbered files placed in a specific location
inside the
Mbox
folder on the RAID hard-drive. The actual parent folder of the image files will depend on the effect or
transition in question:
+
Alpha Mask From File Effect -
Mbox/plugins/images/masks/…
+
Custom Wipe Transition and Shaded Material Effect -
Mbox/plugins/images/grayscale/…
Within each of these folders, you may have numbered files. In the case of the Alpha Mask effect, you may have up to
255 files, numbered 001 – 255. In the case of the Custom Wipe transition, you may have up to 20 files – ten are hard-
edge wipes 001 – 010, and ten are soft-edge wipes 011 – 020. Numbering, naming, and file extensions conventions
follow the same rules as standard Mbox content. [e.g. 001.MyFile.png]
Guidelines:
+
The input image files must be sized appropriately for their intended purpose. To use the Alpha Mask effect on a
layer, make sure the additional input image file is the same size as the content you wish to use it on. i.e. If you
want to mask content that is 1024 x 768, you will require a mask file that is also 1024 x 768. To use the Alpha
Mask effect on the Master fixture, make sure the input image file is the same size as your fullscreen output size. To
use the Custom Wipe, make sure the additional input image file is the same size as the content that you are using
it with. For best results the outgoing and incoming content also need to be the same size.
+
The Alpha Mask input image file must be either a PNG or TIFF file saved with an alpha channel. The effect uses
the alpha channel information in the input file to generate the mask.
+
The Custom Wipe input image file can be a JPG, PNG, or TIFF and can be grayscale or color. No alpha channel is
required since that information is ignored. The grayscale file will provide the best indication of how the transition
will work, as this effect uses luminance values to create the wipe. The darker areas will start to show the incoming
content first, followed by lighter areas.
