Embed cue points

Cue points cause the video playback to trigger other actions within the presentation. For example, you can create a Flash presentation video playing in one area of the screen while text and graphics appear in another area. A cue point placed in the video triggers an update to the text and graphics, letting them remain relevant to the content of the video.

Each cue point consists of a name and the time at which it occurs. You specify cue point times in hour:minute:second:milisecond format; the default frame rate is 30 fps. You can specify cue point times with any frame rate, and also express them in milliseconds rather than frame numbers.

To define and embed cue points, use Flash Video Encoder or import a video clip using the Video Import wizard.

  1. From the Encoding Profiles panel of the Video Import wizard, select a predefined encoding profile from the Flash Video encoding profile pop-up menu, or create your own custom encoding profile using the encoding options in the Video tab.
  2. Click the Cue Points tab.
  3. To locate a specific frame (point in the video) to embed a cue point, use the playback head. For greater precision, select the playback head, and use the left and right arrow keys to locate specific points in the video. To locate a specific frame, use the pointer to move the playback head to the point in the video to embed a cue point. The video preview window visually identifies points in the video at which to insert a cue point. To locate specific points in time at which to embed cue points, use the elapsed time counter (located beneath the video preview window).
  4. When the playback head is positioned on a frame where you want to embed a cue point, click the Add Cue Point button.

    Flash Video Encoder embeds a cue point on that frame of the video, and populates the cue point list 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 is 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 appears on the slider control at the point where the cue point was embedded. To adjust the placement of the cue point, use the cue point marker.

  5. Specify the type of cue point to embed:

    • Event cue points trigger ActionScript methods when the cue point is reached, and synchronize the video playback to other events in 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.

  6. 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.
  7. (Optional) Save the cue points you’ve created so that you can apply them to other video clips. Click the Save Cue Points button (the disk icon) on the cue points tab, and save the file to a location on your computer..
