Cleaning Motion Capture Data

[Siddartha]

Hello Everybody,

i registered today but not able to find what im looking for, so i hope u can help me. I have a lot of Motion Capture Data. It was an optical system, so the balls bounces little bit and its like theres a noise filter on the animation :-) So i want clean them. The problem is that theres a key on each single frame, cleaning manually is nearly impossible. Im looking for a way to reduce a huge amount of keys. Max isn´t as good as xsi in that, but i dont want to lern xsi. now im looking for a better way or reduce with motion builder. I found the reduce key filter in motion builder, but dont know how to enable that. the help file says choose a region in the f curves, but there are no curves in there :-)
Greetings

Your all over the place. Mocap are only used for the biped are you trying to say you want to put multiple moves on your biped? You can put a number of move on a single biped all you have to do is use the motion flow graph editor.

You need to stick with one subject i'm totally confused also you need to run your spelling through the checker before you post it also learn how to use the enter key when your asking another question...

To make the bouncing ball you need to use the time slider at the bottom of the 3ds max tool bar if the bounce is not the way you want it then you need to use the dope sheet and the CV editor when you have your object selected. You can clean the animation key by selecting them in the slider time slider and hitting the small delete key or the backspace key.

do the tutorial that is under the help file and tutorial in max

To the fourm monitor sorry if this sounds rude but i am totally confused, It was not meant to sound rude

Hi Siddartha,

If you select a range of keys, can you run the reduce?

Hello

sorry if my spelling is so bad, but i cant´t understand why u are confused! I know how to bounce a ball, thats not the problem :) I mean this optical reflection balls uppon motion capture suites. I dont want to let a ball bounce in my animation, thats long time ago ;)

Now again, i have motion capture files, csm files, bvh, c3d whatever. if i load them on a biped, the biped is doing the animation fine, but the problem is that theres a key in every frame ( and inbetween frames) i can add a new animation layer and correct the animation, but i cant reduce the keys.

The animation has a lot of jitters, because the balls are moving on the suit a little bit although the arm is not moving, so there are jitters. If i reduce the keys, the jitters are gone :)

Im looking there for a tutorial to reducing keys in max or motionbuilder.

What ive done in short,

in max, creating a biped, load the csm file on in, go to dope sheet editor, select all keys, reduce key
in motionbuilder, import the fbx from max, got to fcurves, in the filter menü, choose reduce key and accept

in both cases, nothing happen

Hope u can help

If you go into the CV editor and selecting your object (biped) then you will see the animation time line and you can change it by selecting the point and dragging it up, down left or right.

Also in the time slider you can move the keys to where you want them to go by pressing the alt and moving them with the mouse.

Csm are not made for max 9 csm are made for cinema 4d, Bvh is made for max.

Of course you can add a new layer but unless you fix the animation in the CV editor then you will have the same problem. If you fix the problem in the CV editor and then add the new layer you should be fine.

In what way do you want to reduce the keys do you mean in the time configuration where you want to have a number of key frames (example say you have 50 frames of animation and there is a 100 fames and 50 is all you want) if so you can click the time configuration on the very bottom tool bar where you have the pan icon you’ll see a clock with a box in the background click that and you can change the number of frames you have under the animation start from 1 to end time 50 for example.

The reason your animation is jitter is because of your VGA (graphic) card is not powerful enough so you would need to update your drivers or go out and buy a new VGA card. Something with shader 3.0 or above.

all the tutorials are on the dvd you will need to open the dvd look for the tutorial folder and drug them to your hard drive and put them in the autodesk folder. If you click on the help file the references are there and max come with the manuals and tutorials.

if you go through the tutorial in max and use the tutorials page you would know the answers

Now i think you dont want to understand me :-)
I know how to move points up and down or move the keys in the timeline, but thats not the question.
I asked how to remove and reduce keys.
Now again...
I load a motion capture animation on a biped and then every frame is a keyframe. If you animate by hand, you set a key maybe on frame 10 and go to frame 20 and say move the arm, for this 10 frames you have 2 keyframes. the other frames are interpolated. If you use motioncapture data, every key is a keyframe, even inbetween keys. The position of the arm is absolute on every frame, thats why the animation jitters and NOT because a bad VGA Card. Its a Quadro FX 1700 with Shader 4.0. I think that should be enough to let a stupid biped move without jitters :-)
I asked how to reduce this keyframes. i want a smooth animation and remove all unnecessary keyframes.

[libertycityanimation]

i was right the first time go into the Track View > Curve Editor or Dope Sheet > Highlight the keys to reduce in the Key window. > Keys menu > Reduce Keys

Track View > Curve Editor > Highlight the keys to reduce in the Key window. > Keys: Track View toolbar > Reduce Keys

I am not writing a whole tutorial because i don't get paid for writing them

Hey! Cleaning up motion capture data can be a cumbersome task :) To reduce keys in Max, select the animated object(s) and, in the Curve Editor, choose Keys>Reduce Keys. It's a good idea to first make sure you have the tracks you'd like to reduce selected. The more you increase the Threshold value, the more keys you will remove, so use caution.

Also, thanks for offering your help, libertycity :)

Hope this helps!

delano,
