MACROMEDIA FLASH 8-USING FLASH VIDEO ENCODER Use Manual page 23

6.
Use the playback head to locate a specific point in the video where you want to embed a
cue point. For greater precision, you can use the left and right arrow keys to move the
playback head in millisecond increments. To do this, select the playback head, and then
use the arrow keys to further adjust its position.
To locate a specific time, use the cursor to move the playback head to the point in the
video where you want to embed a cue point. The video preview window lets you visually
identify points in the video at which to insert a cue point. You can also use the elapsed
time counter (located beneath the video preview window) to locate specific points in time
at which to embed cue points.
7.
When the playback head is positioned at a place in the video where you want to embed a
cue point, click the (+) button on the left side of the Cue Points tab.
Flash Video Encoder embeds a cue point at the time indicated by the counter beneath the
video preview window, and populates the cue point list with a placeholder for the name of
the new cue point and the elapsed time at which the cue point is located (this is the time
during playback when the event will be triggered), and 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 further adjust the placement of the cue
point. For greater precision, you can use the left and right arrow keys to move the cue
point marker in millisecond increments. To do this, select the cue point marker, and then
use the arrow keys to further adjust its position.
Only one cue point can be embedded at a specified time code within the video clip.
8. Specify the type of cue point you want to embed. You can embed either a navigation or
event 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 to enable viewers to seek to that place in the
video.
Adding additional keyframes can lower the overall quality of a video clip. For this
reason, navigation cue points should only be used when users will need to seek
to a particular place within the video. For more information on keyframes, and
their effect on video playback, see "Keyframes" on page
