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. 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:
+
For the best results, the input image files should be sized appropriately for their intended purpose. However, this
is not necessary as the Alpha Mask effect and Custom Wipe transition input images will be scaled to fit the
content they are used with. This can result in a mismatch between the aspect ratio of the input image and the
content though. When using the Custom Wipe, for best results make sure the outgoing and incoming content are
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.
