  1. According to this old thread Houdini only accepts mocap data if its Acclaim, Biovision or Motion Analysis. I would like to try using some of the data from CMU http://mocap.cs.cmu.edu I can only see acronymns for tvd, c3d and amc Any mocap experts that might tell me whether I should have any luck with any of these formats?
  2. Keyframe Reduction?

    I am trying to work with Mocap data that I have recorded in Vicon Blade. I have an FBX of the solving setup that I have imported into Houdini and I have been able to work with it and get the setup where I want it to be, but I am running into an issue with file size. I am currently sitting at 189MB and I am pretty sure that about 95% of that is keyframe data. Unfortunately when I start working with the file it explodes in my memory and is becoming unwieldy. I am talking in the 25gb range. The Motion Capture data has placed a keyframe at every frame for all of the bones, which is definitely overkill. Is there any way of automatically reducing keyframes in Houdini? I have seen the tool in some other packages, but I am trying to figure out how to do it here. If there isn't a built in way to do it, is there any way I can delete keys in CHOPS, because I could see writing a VEX expression for doing it. Something along the lines of calculating the slopes and if the slope from one keyframe to the next is below a certain margin, delete. Or hell, I could just check concavity at each keyframe and only keep the ones where it changes, but I need to know if there is a way to delete the keyframes.
