I was just searching the net and didn't find anything useful yet. So I thought I'll ask my fellow fxhomers if they might know anything...

I'm looking for a software based motion capture solution. An application you can use to analyze videodate and extract motion capture data from.

I'm pretty sure there must be something like that around, but I can't find it.



If anyone knows anything, I'd be most thankful. smile


(preferably for mac, but pc is okay too)

you know how sometimes you see footage of people like doing stuff wearing black suits with little white thing son them. Thats motioncapture, its used alot in games to simulate real actions of say football players. They used motioncapture on Gollum, so the movements would like more lifelike.

Hm, motionbuilder seems to be designed to work with motion capture, but not doing motion capture itself... or am I just stupid?

And the other two seem to require MoCap hardware. :I

Yeah. So I've ssen.

I need a tool though to actually capture mocap data from videofiles though. Not sure if any of these apps can do that. Still reading through it all though.

I've downloaded the demo. But couldn't find anything about extracting data. Just how to work with already existing data.

I'm currently trying to check out certain possibilities.


Getting actual MoCap hardware is by far too expensive. So I'm trying to find a software to help me extract MoCap data from a videofile.

I believe that what you're looking for is video-based motion capture software. These are what I've found so far

Couldn't find any more (found some interesting thesis articles though on the subject). I'm going to try out the top one myself, considering it's free, but let me know how it works for you.

Sollthar, how complex is the motion? I've used a technique called Rotoscoping (although I think that term is used way to much...)

1. Shoot your actors in front and profile, (It worked for me just using the profile footage)

2. Take the footage into your 3D software and throw it in the background.

3. Match your CG charater to the same angle and stance as in the footage.

4. Identify keyframes for your movement.

5. Key your CG character at those keyframes.

You now have some movement that, while it isn't as accurate as motion capture, yeilds alot more realistic results, and contains many of the nuances<sp> that you would get in motion capture that animators tend not to throw in to their work.

The first time I went through this I had many people convinced the movement I had was MoCap. So for your average person, this works effectivly if done correctly. smile

Yeah, I did that a couple of times and it does work quite nicely. Allthough I'm really looking for a quicker way to do it. smile

But yeah, that technique is quite good.

MotionBuilder's mocap engine is designed for use with dedicated Mocap hardware systems like PhaseSpace or Vicon systems.

To capture from video, you'll need video from at least two cameras that were shooting at the same time. More cameras is preferred.

I've done DV based mocap using MatchMover pro from RealViz and 3-4 miniDV cameras. (http://www.realviz.com/products/mpro/index.php)

I believe SynthEyes is also now claiming mocap abilities.
There is also a freeware program called DGeeMe that claims to handle this:
http://www.geeware.com/
I've never tried these last two solutions.

Hope this helps.
Good luck.
Have fun.

Here are some programs that may help you:

Life Forms Studio 4.0:

http://www.credo-interactive.com/products/lifeforms/index.html

And get these motion capture files while your there:

http://www.credo-interactive.com/products/motion_capture/index.html

Only if you think its worthwhile. It may be expensive, but its kool.

~or~

And soon I'll be compililng information about 3d programs, rendering,
mo-cap, composting and more!
