Ok for now i have no correct test data. But if i try to open a BVH file (created with MakeHuman) in Blender in the MakeWalk - Toolbox, i only get error Messages. Ill try again if i have "good" files. For now iam far away from the screens in the tutorial

Worked all well for me. For testing try animstreet or the CMU labs bvh files.
Didn't know Makehuman can crate BVH files grin
edit: ah, only the rig, not animation. Ok.

just use mhx export. When having installed Blendertools you can jsut import this format and it will load perfectly.

Ok first BVH added to a MHX export. grin

Cant wait to see how it works with one of my biped zombie models. Hope will work.

Is there any option like "Keep Model / Animation in place" ?

I couldn't find one - so I added a correction bone between the feet.
Then I added keyframes for this bone to make the model walk in place. It seems to be a rather common practice.
You can also try to modify existing keyframes of the root bone, but this can be annoying when there are many keyframes available, as you have to adjust each and every of them. With a correction bone you usually get away with less.
You can correct either in the 3d view, which can be tedious or you might want to try Blender's curve editor which displays all changes to bones and their properites (xyxz pos, rotation,...) as lines.... similar to the Unity animation curve editor.

That's the fine tuning which has to be done for nearly every animation. Especially walk and run, as capturing a walk in place aniamtion will deliver rather unrealistic results.

Maybe constraints can help there, but I haven't looked into that yet.

Sounds not easy for animation noobs like me.
Maybe in Brekel's Kinect theres an option to "Keep mocap data in place" (?).

edit: If ive the first BVH please explain in detail then, iam sure ill have some questions then

Did some research...

Realtime Streaming into Blender seams to work with this Script:
"Delicode Ni Mate" - free

To keep the animation sequence in place the following tool seams to work:
"BVHacker" - free

Both not tested yet.

Edit: Email from Amazon. Maybe adapter arrives 2.Juli not 6th.
