How can I resize an object during a video?

Development Getting Started & Setup

Hello,

I can't find how to resize an object during a video shot.

I have a vertical bottle and want to simulate liquid moving down by resizing a cylinder.

I just can't find how to create a simple interpolation on keyframes.

Thank you for your help.

Depending on your model, is it possible to use a Translator (within Animators folder) to move the cylinder down rather than resizing it? As long as the surface the bottle is sitting on will accommodate the lowered cylinder without it showing. The motion can be triggered by the camera approaching.
