How to Transfer Motion Between Characters with Claude
Transfer motion between characters with Claude and ToolRouter. Apply realistic movement from a reference video to custom illustrations and avatars.
Tool
Apply the movement from one video to a different character, transferring motion onto illustrations, avatars, or photos. Claude is most useful here when you're developing the creative brief — deciding which motion clip to use, what adjustments to make, and how the transferred motion will be used.

Steps
Once connected (see setup above), use the Character Animator tool:
- Provide the reference motion video and the target character image, and describe the intended output context.
- Run `transfer_motion` through `character-animator` to apply the motion to the target character.
- Ask Claude to evaluate the result — does the motion map cleanly to the character's proportions, does the movement feel natural, are there any obvious artifacts?
- Refine if needed and export the animated character for the intended use case.
Example Prompt
Try this with Claude using the Character Animator tool
Use character-animator to transfer the walking motion from this reference video onto my custom character illustration. The character is a cartoon robot — the movement should feel mechanical but fluid. Review the output and tell me what looks off and what to adjust.
Tips
- Reference videos with clear, unobstructed full-body movement produce the cleanest transfers.
- Ask Claude whether the motion maps correctly to the character's proportions — stylized characters with unusual limb ratios can cause mapping issues.
- Short loops (3-8 seconds) transfer more consistently than long sequences.
