Importing video using the Video Import wizard 289
Embed as a graphic symbol Embedding a video clip as a graphic symbol means that
you cannot interact with the video using ActionScript (typically you use graphic symbols
for static images and to create reusable pieces of animation that are tied to the main
Timeline). For this reason, you’ll rarely want to embed a video as a graphic symbol. For
more information, see
“Types of symbols” on page 79 .
5.
Import the video clip directly onto the Stage (and the Timeline) or as a library item.
By default, Flash places the video you import on the Stage. If you prefer that the video be
imported only into the library, deselect the Place Instance on Stage check box.
If you’re creating a simple video presentation with linear narration and little to no
interaction, accept the default setting and import the video to the Stage. If, however, you
want to create a more dynamic presentation, are working with multiple video clips, or
intend to add dynamic transitions or other elements using ActionScript, import the video
into the library. Once a video clip is in the library, you can customize it by converting it
into a MovieClip object that can be more easily controlled using ActionScript.
By default, Flash expands the Timeline to accommodate the playback length of the video
clip you are embedding.
6.
(Optional) If you want to edit the video clip using the Video Import wizard, select the Edit
Video First check box.
The Video Import wizard includes basic video editing options that let you crop and trim
video clips. If you want to edit your video clip prior to embedding it in the Timeline,
select this option.
7.
(Optional) If the video clip is not yet encoded in the FLV format, select a Flash Video
encoding profile.
For information on encoding profiles appropriate to your intended application, see
“Selecting a video encoding profile” on page 293 .
8. Click Finish to close the Video Import wizard and complete the video import procedure.
The Video Import wizard encodes your video into the FLV format, and embeds the video
into the SWF file. The video is displayed either on the Stage or in the library depending
on the embedding options you chose.
9.
In the Property inspector (Window > Properties), give the video clip an instance name, and
make any modifications to the video clip’s properties that you might need.
For more information, see “Changing the properties of a video clip” on page 301 .
