No animation without video?

I'm running ComfyUI stand alone. <img width="722" height="260" alt="Image" src="https://github.com/user-attachments/assets/90769316-cf36-4b4e-b66a-392732f38714" /> I installed your custom node and want to animate some expressions into a small video. Installation went smoothly without issues. Unfortunately I was not able to do that. No matter what I try, I can't generate any movement. Are there any requirements that need to be set or taken into account? Here the settigs I have used. Any advice or suggestions what went wrong here are welcome. <img width="703" height="553" alt="Image" src="https://github.com/user-attachments/assets/f966c5ac-1a67-4b00-ab2c-dfdc8f634c54" />
