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/
+ MetaImage Effect - /Mbox/plugins/images/masks/
+ Custom Wipe Transition - /Mbox/plugins/images/grayscale/
Within each of these folders, files will have 8-bit numbering. The Alpha Mask and MetaImage effects share the same
folder, there may be up to 255 files, numbered 001 – 255 to share between those effects. The Custom Wipe Transition
can only have up to 20 different input files – ten are used for hardedge wipes 001 – 010, and ten are used for soft-edge
wipes 011 – 020. Numbering, naming, and file extensions conventions follow the same rules as standard Mbox content.

Guidelines:
+ The input image files do not have to be the same size as the texture they are applied to (layer or master) because
they are automatically scaled to fit. However...
-
Alpha Mask effect: For best results with files used for accurate masking, the input image file should be exactly
the same size as the texture it will be applied to. Make sure the input image file is the same size as the content it
will be used on. i.e. Masking content that is 1024 x 768 would require a mask file that is also 1024 x 768.
-
Custom Wipe transition: Input image files that are not the same aspect ratio as the texture on the layer may lead
to undesirable results. For best results the outgoing and incoming textures should also be the same size.
+ The Alpha Mask input image file should be a PNG 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 or PNG and can be grayscale or color. No alpha channel is
required. A 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.
