Example 3 How to Add Holds to a Movie
Hold is simply a segment of a movie where the motion is frozen.
This is done with adjacent KeyFrame Markers that have the same value
offset by the Hold period in the Timeline. This example adds a
two second Hold to the looping movie created in Example 2. Next
we add two seconds to the end (zoom-in) segment since we shortened it
by inserting the Hold two seconds in at the 12 second point. The
files associated with this example may be downloaded by clicking on
the download icon. The files are contained in a self extracting
.exe so simply click on the downloaded file and the test files and resulting SWF file will be loaded into
your selected directory. Click on the Download Icon to download

1 Figure 1 shows the screen at the end of Example 2. The
Timeline shows middle KeyFrame Marker at ten seconds into the the
movie. The start KeyFrame Marker was copied to the 20 second
point in the Timeline to create a zoom-in / zoom-out effect with
equal in and out times of ten seconds (see Example 2).
2 To create the two second Hold a copy of the KeyFrame Marker is
placed at the 12 second point on the Timeline. See Example 2
Step 2 for a review of Cut and Paste.
the Duplicate KeyFrame Marker is Pasted to the Timeline the word Hold
bounded by indicator lines appears on the time line. The Timeline
with the Hold inserted is shown in Figure 2
Note: • The insertion of the Hold or any Paste
operation will not effected the position in the Timeline and the
consequential timing of movie. The effect will shorten the next
segment by the time of the insertion.
3 Because we want the zoom-in and zoom-out periods to be the same
we must increase the duration of the final segment by moving the
KeyFrame Marker two seconds further along the Timeline. This is
done by moving the mouse cursor over the KeyFrame Marker and then
dragging it to the desired position.
• Dragging a
KeyFrame Marker does not effect the position of any other Marker on
the Timeline but will effect the timing of the adjacent segments.
Figure 4 The Flash Movie made in the example, note
the two second Hold
Step 4 Preview the Movie using the
Viewer Window's VCR-like
controls. You will see the Movie zoom-in, freeze for two
seconds and then zoom-out to
its start. Create the Flash Movie as in
Example 1 by Selecting the
Make Flash SWF Movie entry under the File Menu. See
Example 1 Step 4 for details.
• The 22 second
movie shown as Figure 4 requires only 27,746 bytes and is being
displayed in 320 by 240 pixel resolution. The movie in Example
3 is two seconds shorter and is 27,709 bytes in size. The two
second Hold only added 35 bytes to the file size!!
