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.
Cropping and trimming video
Flash Video Encoder provides the following editing options that let you crop and trim video
clips before encoding them:
Cropping
lets you alter the dimensions of a video clip. You can eliminate areas of the video to
emphasize a particular focal point within the frame such as highlighting a character by
removing ancillary imagery or removing unwanted backdrops.
Trimming
lets you edit the beginning and ending points (the in and out points) of a video. For
example, you can adjust the trim of a video clip to begin playback 30 seconds into the full
clip, removing unwanted frames.

From the Encoding panel of the Video Import wizard, click Show Advanced Settings.

To set the in and out points, drag the in and out point markers below the scrubber bar until
you finish adjusting the video clip size. For greater precision, select the in and out point
markers, and use the left and right arrow keys to locate specific points within the video.

you can trim the video clip. You can also use the elapsed time counter (located in the
Trim section of the dialog box) to locate specific points in time where you can trim the
video clip.
