About creating menus in After EffectsEncore and Adobe After Effects
contain several integrated features to help you create dynamic motion
menus. Using After Effects, you can animate elements of a
menu so that, for example, the button images fly into position or
fade in over an image or video. The composition you create can then
act as a video background to the actual menu in the project. This
advanced technique requires an understanding of After Effects,
video backgrounds, and the use of the loop point to initially disable
buttons.
In After Effects you can also create a menu from a composition
and then import it as a menu into Encore. The After Effects
Create Button command lets you assign button subpicture layers and
a video thumbnail layer for each button set. It adds the appropriate
layer-name prefixes to them. The Save Frame As command lets you
save a frame as a layered Photoshop file. For information on creating
buttons or layered Photoshop files in After Effects, see Working
with Adobe Encore and After Effectsin After Effects
Help.
Overview of animating a menuIf you have After Effects 7.0 or later, you can
use the Create After Effects Composition
command in Encore to quickly start a menu animation. This command
converts a menu into an After Effects composition and opens
it in After Effects.
The basic steps to animate a menu using this command are as follows:
1. Create a complete version of the menu.Using either Encore or Photoshop, design
the menu that contains the elements you want to animate, as well
as the final resting position of the text and button images. You
use this menu as the basis for both the animation and the final
menu. Place each element on its own layer so that you can animate
the elements separately. Creating the composition from a complete
version of the menu ensures that the button subpictures correctly
overlay the buttons.
2. Create an After Effects composition from the menu.If you created the menu in
Photoshop, import it as a menu. Choose Menu > Create After Effects Composition
in Encore to start After Effects and automatically convert
the menu into a layered composition.
Each button set becomes
a nested composition within the master menu composition. Because
it is based on the actual menu, the composition contains the elements
you want to animate and their correct ending position on the screen.
If you animate the button images or delay their display initially,
it is important to keep them visible for the remainder of the composition,
because the image of the menu in the movie file acts as the visual
menu in the project. In other words, the background video you create,
not the menu, contains the button images. When the animation is
complete, you create a rendered file from the composition.
 A good practice is to create a layer marker in
After Effects at the frame where you want the animation
to end and the menu looping to begin. Name this marker “Loop Point,”
and set an ending keyframe at this same location for each attribute
you plan to animate. Doing this ensures that your button highlights
line up correctly when you bring the finished animation into Encore.
3. Hide the animated layers in the original menu.Using the Layers panel in Encore,
hide all the layers that you animated so that they do not appear
over the background video.
4. Import the video file and link it as a video background to the menu.Import the
video background you created as an asset into your Encore project. Then,
using the Properties panel, link the video to the menu so that it
replaces the menu background.
5. Set the menu Loop Point.In
Encore, use the menu property Loop Point to designate at what point
in the display of the menu the buttons appear. Buttons cannot be
selected or activated by the viewer until the Loop Point frame is
reached. Once the menu starts looping, the buttons are enabled.
The loop begins at the loop point and ends at the end of the movie
file. The initial animation plays only when the menu first starts.

Encore lets you import
and work with menus that aren’t standard sizes. For example, you
can import a 720 x 534‑pixel menu (created using square pixels) into
an NTSC project (frame size: 720 x 480 pixels). However, if you
create a composition from a menu of these dimensions, you need to
scale the layers in After Effects. To ensure that the menu
in the project aligns precisely with the pixels in the background
animation, it is best to resize nonstandard menus in Photoshop before you
create the composition. For standard definition (SD), resize an
NTSC menu to 720 x 480 pixels and a PAL menu to 720 x 576 pixels.
For high definition, resize square-pixel menus to 1280 x 720 or
1920 x 1080 pixels, and resize nonsquare anamorphic menus to 1440
x 1080 pixels. (In Photoshop, you can also specify the pixel aspect
ratio for the menu: For a SD NTSC menu, choose 0.9 for fullscreen
or 1.2 for widescreen; for a SD PAL menu, choose 1.066 for fullscreen
and 1.42 for widescreen. For HD square-pixel menus, choose the 1.0 pixel
aspect ratio and for HD anamorphic menus, choose 1.333.)
Create an After Effects composition from a menuIn Encore, select the menu that
you want to animate in the Project panel.
Choose
Menu > Create After Effects Composition.
The
menu saves as a PSD file and opens as a project in After Effects.
The layer sets and buttons convert to nested compositions.
In After Effects, animate the menu elements as desired.
Set keyframes for position, scale, rotation, or any effects at the
times when you want the animation to start and stop. For example,
you can have each of three buttons rotate for 5 seconds at staggered
intervals. Don’t make the button subpicture layers visible in the
composition because they must remain part of the menu in Encore.
Convert text layers to editable text if desired.
Render the movie as a video file. Choose Include Project
Link from the output module settings in the Render Queue panel.
You can return to After Effects directly from Encore to
make adjustments if necessary.
In Encore, double-click the original menu to open it.
Choose File > Import As > Asset,
select the video you created in After Effects, and click
Open.
In the Layers panel in Encore, hide any layer that is visible
in the composition by clicking the Eye icon next to the layer. If
you animated the button images, open their button sets and hide
the visible layers.
With the menu selected in the Project panel, click the Motion
tab in the Properties panel, and drag the Video pick whip to the
After Effects-produced video clip in the Project panel.
Because
the menu is in animation, the video clip takes the place of the
actual menu in Encore while still maintaining its original properties
such as the button highlights.
Specify Loop Point and Loop # values. (See About menu display time and looping.)
