with a placeholder for the name of the new cue point, and the elapsed time and video frame at which
the cue point is located (this is the time during playback when the event will be triggered). Flash
Video Encoder also displays a pop-up menu that lets you select the type of cue point to embed.
A cue point marker is displayed on the slider control at the point where the cue point was embedded.
You can use the cue point marker to adjust the placement of the cue point.
Specify the type of cue point you want to embed, an event cue point or a navigation cue point:
Event cue points are used to trigger ActionScript methods when the cue point is reached, and let
you synchronize the video playback to other events within the Flash presentation.
Navigation cue points are used for navigation and seeking, and to trigger ActionScript methods
when the cue point is reached. Embedding a navigation cue point inserts a keyframe at that point in
the video clip.
Enter parameters for the selected cue point.
Parameters are a set of key-value pairs that you can add to the cue point. The parameters are
passed to the cue point event handler as members of the single parameter object.
Video alpha channel support You can now use an alpha channel with video objects, allowing you
to create transparency effects.
To use a video file to create the alpha effect in Flash, the video file must contain an alpha channel.
In general, the video file must meet the following requirements:
• 32-bit video with million+ colors
• Includes a color-key background
• Is encoded to enable the alpha channel
