Duration : 20 Frames.
We only modify the tab 'Transforms' so that at Start the text begins to move below the zone (Y < 0) being transparent.
It goes up having 25% of red color in the middle of its course and 100% when it finishes at the center of the scene.
Test the effect clicking in the property box, then button
3 - In 'Timeline', click Frame 25 in row 'Ceci', then 'AddEffect' and 'Alternate'.
Duration : 20 Frames.
This time, we apply the inverse effect from the previous one.
We only modify the tab 'Transforms' so that at Start, the text begins from last position (center of the scene) being opaque.
The text goes up having 25% of red color in the middle of its course and becomes fully transparent at arrival. Test the effect.

5 - Repeat §1 & §2 for text 'défilant' at 40.
You should get
In this example, all objects have the same effects but delayed. You can try other evolutions but it is advised to write parameters you change because the possibilities are huge. Only modify a parameter at a time and test the result immediately.
