Animation in Cascadeur is created within scenes.
A scene contains objects and animations.
Cascadeur includes several pre-made scenes with animations and characters.
If you would like to create several distinct animations involving the same character, the best way to do this is by using separate scenes.
For example, you can save the scene right after you finish making the rig for your character.
To create a new animation, open this scene and then save it as a separate file under a different name.
Use the Save as option from the file menu.
By doing this you won’t have to rig your character from scratch every time you make a new animation.
You can also combine several scenes into one.
