Adobe ENCORE 2 Manual page 111

Create a layer set (also called a layer group) and add (+) to the beginning of its name. Include the parentheses.
3
Create a placeholder for the video thumbnail within this layer set. You can draw the placeholder or place a still
4
image.
If you use a shape tool, such as the Rectangle tool, to draw the placeholder, the shape of the layer becomes the mask
for the video thumbnail. You can also create a layer, draw a selection with the Rectangular Marquee tool, fill the
selection with a color, and then click the Add Layer Mask button in the Layers panel. The layer mask becomes the
mask for the video thumbnail.
You can constrain the Rectangular Marquee to the screen aspect ratio by using the Style option Fixed Aspect. Set the
value for Width to 4 and for Height to 3 (or to 16 and 9 for widescreen video).
In the Layers panel, double-click the layer name of the placeholder image, and add (%) to the beginning of its
5
name—for example, (%) Rigging Thumbnail.
Put any additional elements that you want in the button, such as text, within this layer set.
6
You can also add layer effects, such as drop shadows, glows, and transparency, to thumbnail layers in Photoshop.
7 Repeat steps 3 through 6 for any additional thumbnail buttons you want to create.
In Photoshop, choose File > Save, and then choose File > Close.
8
Photoshop saves the changes and updates the menu in Adobe Encore DVD.

To specify a poster frame
Video thumbnails play the video of the timeline to which they are linked. If the thumbnails in the menu are still (the
menu property Animate Buttons is deselected), they display the first bright (non-black) frame of the destination link.
You can change the start point or the still image displayed by a thumbnail by designating a poster frame. A poster
frame is not limited to a chapter; you can place it on any frame in the timeline. If the button loops, it loops back to
the poster frame rather than the destination chapter. (See "About Loop Point" on page 108.) The Poster option is a
chapter property.
Open the timeline that is the destination for the video thumbnail button.
1
If the Monitor panel is hidden, choose Window > Monitor.
2
3 In the Monitor panel, move the current-time indicator in the timeline to locate the exact frame you want displayed
in the thumbnail.
Choose Timeline > Set Poster Frame.
4
A Poster marker with its associated chapter number appears in the timeline, and the timecode for the frame is added
to the chapter properties in the Properties panel.
You can also create a poster frame by Ctrl+Alt-dragging from the chapter marker in the timeline to the desired frame.
