Step 3: Creating more Keyframes
- Add Blank Keyframes (F7) to Frame 11 on BOTH Layer 3 and
Layer 2.
- Add a Frame (F5) to Layer 1 at Frame 11.
Step 4: Reuse the black
rectangle animation on Layer 3
- Highlight Frame 1 through Frame 10 on Layer 3,
- Hold down the Alt Key and click and drag the highlighted
frames over to frame 12. This will copy the frames. You should
now have a Shape Tween from Frame 12 to 21.
Step 5: Add another image to
the masking animation
Now, here's where it gets a little tricky
- Copy the image on Layer 1 (right click on Frame 1, choose
Copy Frames) and paste it to Layer 2 at Frame 12 (right click
and choose Paste Frames). This is because we want to add
another image to our masking movie and that new image needs to
go on the bottom layer.
- On Layer 1, add a Keyframe (F6) to Frame 12.
- Delete the image at Frame 12 on Layer 1 and add a new
image.
- Add Frames (F5) in Layers 1 and 2 at Frame 21. You should
now have equal Frames for all 3 layers.
Step 6: Test your movie
Lock all layers and preview your movie by dragging the
playhead.
Step 7: Continue adding images
- Repeat the preceding steps to continue adding new images
and wipes.
- You can add Stop Actions and Play Buttons to increase
interactivity with the masking.
- You can also use rectangles that have gradients on them to
create different transition effects.
