Animate Avatar Skill

Generate animated videos from static avatar images for use in apps, websites, or social profiles.

Overview

This skill automates the process of:

Generating multiple video animations from a static avatar image
Optimizing videos for web delivery

Activity Philosophy

Default Generation: Create 3 videos per avatar:

2 Work activities - Shows the character being productive

This 2:1 ratio of work-to-relax creates variety and humanizes characters.

"Character giving a presentation with gestures"
"Character thinking deeply, tapping chin"
"Character nodding while listening attentively"
"Character examining something closely"
"Character taking notes with a pen"

Relax Activity Prompts (pick 1)

"Character drinking coffee or tea"
"Character playing a small guitar"
"Character eating a snack happily"
"Character stretching and yawning"
"Character listening to music, bobbing head"
"Character waving hello cheerfully"

Tips for Best Results

Good Prompts

Keep motions subtle - loops better
Match the character's personality
Work: typing, writing, presenting, thinking
Relax: drinking, stretching, waving

Avoid

Large movements that break the loop
"Walking", "running", "jumping" - too dynamic
Complex multi-step actions
