2. Copy two copies, select one of them, cut off the picture scroll, leaving only the scroll-because the head of the scroll is wide, you can only cut straight lines when cutting, so there is still a little remnant of the picture scroll next to it at this time:
3. Draw a rectangle to block this part of the picture scroll, then hold down the Ctrl key, select the picture and rectangle, and use "Merge Shape-Cut" to cut off the redundant picture scroll-the left in the following picture shows before cutting, and the right shows after cutting:
4. Treat the right scroll in the same way, or simply copy the processed scroll, turn it horizontally, and put the two processed scrolls together horizontally:
5. Cut another previously copied material and keep the picture scroll. If you have any picture material to show, you can put it in a suitable position on the picture scroll at this time and make it into a group with the picture scroll:
6. Put two scrolls on this scroll:
Then draw a rectangle on the left and a rectangle on the right to block the external picture of the scroll:
7. The rectangle is filled with white borderless lines, the scroll is placed on the top layer again, and the plane part is completed:
8. Add "cascade" on two rectangles to exit the animation, the direction is left and right, and the time is 3 seconds, so that the following picture scroll can be unfolded (why not directly erase the picture scroll facing both sides in the middle? Because the erase animation has imaginary edges):
9. Add linear motion animation to the two reels for 3 seconds, and adjust their respective directions and ending positions to the two ends of the reels (if you can't find the exact position, you can adjust the rectangle back to blue):
Double-click the time bar in the animation pane to remove the smooth start and smooth end from the effect options:
The rectangle turns white again and the effect is complete. Display effect:
