Add Image Layer Event 333
Layer Plug-In group
Label—Lets you give the event a unique name,
making it easier to distinguish in a long list of
events.
Layer List—Selectsthecompositor3dsMaxuses
for layering the rendered images in the queue.
Alpha is the default compositor, but you can also
choose from any others you hav e installed. See
theseparatehelptopicsfordescriptionsofthe
compositors that come with 3ds Max.
AdobePremiereTransition—Lets you create a
transition between Adobe Premiere video events.
Alpha Compositor—Composites the two images
using the
alpha channel (page 3–1001) from the
foreground image. The background image appears
wherever the foreground image’s alpha channel
is tr ansparent.
Cr o s s Fa d e —Composites the two images over
time , crossfading from the background image to
the foreground image. The rate of the crossfade
is determined by the length of the Cross Fade
Transition filter’s time range.
Pseudo Alpha —Composites a foreground image
against the background by creating an alpha
channel for the foreground image based on the
foreground image’s upper-left-corner pixel. All
pixels in the foreground image t hat use this color
become tr ansparent. B ecause only one pixel color
becomes transparent, edges of the opaque areas in
the foreground image are aliased. Use this method
when the foreground image is a bitmap whose
format does not have an alpha channel.
Simpl e Additiv e Compositor —Composites the two
images using the foreground image’s intensity
(HSV value) to determine t r ansparency. Areas
of full intensity (255) are opaque. Areas of zero
intensity are t r ansparent. Areas with intermediate
transparency are translucent.
Simple Wipe—Reveals or erases the foreground
image with a wipe transition. Unlike the
Wipe
Filter (page 3–360)
event, Wipe Layer moves the
image, sliding it in or out. Under Setup, you can
choosethedirectionofthewipeandwhetherto
reveal the foreground image (Push) or erase it
(Pop).
About—Provides version/source information
specific to the
plug-in (page 3–1089) .
Setup—Displays a setup dialog specific to the
plug-in. Some plug-ins may not use this button.
Mask group
Chan n e l s—If you are using a bitmap as the mask
file, you can use the Alpha channel, the Red,
Green, or Blue channel, Luminance, Z-Buffer or
Material Effects channel, or Object ID.
Files—Select a file to use as a mask. The name of
the selec ted file appears above the Files button.
Opti ons—Displays the Image Input Options dialog
(page 3–342)
where you can set alignment and
size, relative to the frames of video output. For
animated images, you can also synchronize the
mask with the fra me sequence of video output.
This is the same dialog used for Image Input Event
options.
Enabled—Enables the mask. If this box is clear,
Video Post ignores any other mask settings.
Inver ted—When selected, the mask is inverted.
Video Post Parameters group
V P S tart Time/End Time—Sets the starting and
ending frames for the selected event within the
overal l Video Po st queue. Video Post renders the
event over the number of frames specified here.
Enabled—Enables or disables the event. When
this box is clear, the event is d isabled and Video
Post ignores it when rendering the queue. Each
event must be disabled individually. For example,
