Now you can create any kind of animation you want for the text by using keyframes.
You could also put other things behind your subject/object, like PNGs, or even other video clips.
This method is best used for objects that aren’t moving.
If your object is moving, you can track the mask in Color, or for complex movement, I would use Fusion.
All of this can be done in the FREE version of Davinci Resolve.
