Hey guys, I'm getting tired of animateing in poser becouse of little glitches that cources my penguins to do things i don't want them to do

Is it possible to make these motion capture files is your home?
and that will work with the Jtrout emporor pengun adolt chick and the Daz African penguin?

Thanks.

There are several freeware motion capture solutions, right off the top of my head, there's dgeeme which is currently in beta -

Thanks, I'll cheack this out, hopfully I'll be able to aply the movement to the Penguin Figures.

is this a manual one or dose it do averything once you have your video?

It's freeware, so don't expect a lot.  There are several commercial packages that are available - or you could simply grab a bvh viewer utility and browse the various collections on the web

Thanks,
:)

I want to do my own movements, how exactly dose this one work?
any tutorials anywhare?

Thanks.

Probably the cheapest full body motion capture solution out there right now is at naturalpoint.com. The next cheapest solution is the Gypsy, which gets into 5 digit prices. One alternative is rotoscoping; basically filming your actor doing the movements you want, saving the video as an avi file, placing a plane behind your figure in Poser, and using the avi file as an animated texture. You can step through the frames and adjust the figure to match the pose on the plane prop. In either case it would stand you in good stead to download lots of bvh files from the net, and begin to get comfortable with cleanup procedures. No mocap is ever perfect, and there are lots of body parts (like fingers and toes) that you will have to keyframe. Learning how to take to disparate motion files and stitching them together is also a vital skill (and one that will either teach you the ins and outs of your animation system or drive you bonkers. Or both).

Hmm, doing it frame by frame will take forever.

It all sounds complecated but I'll give it a shot with dgeeme

I'm going  load a BHV file form human movements of to the riging of the Jtrout Emporor penguins,
last time i tried just adding a "Pose" and it streched the legs out and all kinds of wired stuff.
can you stop this for when i do my BHV movement?

I chose motion capture becouse the movement will be better and I hate animating in poser.

Someone mentioned in another forum (on another site) the idea of using After Effect motion tracker as a basis for creating BVH.  That's not a half-bad idea!

Perhaps I'm wrong here, but from my understanding, in order to do motion capture, you need sensors attached to a moving subject in order to input the motion data.  Such systems are extremely expensive.

A solution I've found in working with pre-existing bvh files is to use frequent editing to splice together motions in a way that allows you to use segments of motions that may not go together otherwise.  If you look at the average Poser animation, the action seems stilted in part because the editing does not resemble that to which most moviegoers are accumstomed.  Cuts in films come about every 5 seconds or less, so you can render scenes for a shorter period of time--just enough to get the action you want--and then piece the short bits together in an editing program.

cuts also happen on a movenent :)

I havent got a chance to try out this program yet :(
hopfully it'll be awsome.

You must realize that any BVH file generated from the motion of a human will not translate properly to a  poser penguin figure as the joint rotation info will likely be very Different so you are like wasting your time in this approach
A good test will be to try to use the penguin in posers walk designe
and apply one of the poser walk presets  or even load his Cr2
you will find that he most like will no walk properly
as he is a custom figure.

Some motion capture apps use tracking (kinda like AE's tracking method).  So, ping pong balls on a black suit, which provides the needed contrast to allow the tracker to adequately capture the motion, but definitely, using sensors or even better, a "tracking suit" is the popular method in the industry.
