Description
Simple method on how to scale down motion data for use with chibi-sized models.Important Note:
The figures I used are for demonstration purposes only, they cannot and should not be applied in all circumstances. You will need to make adjustments to match each individual model and motion data set. So for example, when I did my Chibi Music Class video, although all 5 chibis used the same motion, each one required a different set of adjustment ratios (well 4 of them did anyway, Chibi Zatsune Miku and Chibi Miku used the same ratios).

1/. Nendoroids will need to use ratios of around 0.4:0.9 - see his her notes in the comments below for specific details
2/. A useful tool (software) for fine tuning motion data to fit a specific MMD model: http: //yumin3123.at.webry.info/200811/article_1.html

Nope - just have to be good at guessing the correct ratio to use.

You would be correct, the position:angle ratio would be greater for a nendoroid. The reason for this is because the positions of the bones in a nendoroid are distorted relative to the "norm" along with it's physical body.
The tool on Misakiru's blog looks interesting. Should be useful for people who want to/need fine-tuned motion data.
Noting your key points in description above - thanks

Opps - ok gender corrected
Japanese - I don't but based on Google Translate and the screenshots I've more or less figured out how the motion converter works.
Basically, you need to:
1/. Open the vmd file you want to convert
2/. The model that the motion data was built using
3/. The destination model for the modified vmd file
The program calculates the new values based on the relative positions of the center and IK bones. You can also enter parameters manually to fine tune the procedure.

I needed this so much for Sara. Thank you!

All this tool does is scale motions, it works both ways (ie. you can scale up or down) - beats having to manually having to 'redo' motions. Only tricky part is figuring out the right ratios. Like I stated, there is a scientific way to figure the motions, I just don't know the maths for it.
