Encoding media

• 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.

Note:

Adding additional key frames can lower the overall quality of a video clip. For this reason, only use navigation cue points when users need to seek to a particular place within the video.

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.

To learn more about using cue points, and the parameter values they can use, see the following:

Crop, trim, and resize video

Adobe Media 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

outpoints

) 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.
