Motive | Skeletons 1


Hello everyone and welcome to another Motive
turorial video. In this video I’ll be going over a skeleton tutorial. I’m going to be using the skeleton 1 from the
sample data. So I’m going to start by opening my project pane
and let’s open the timeline too. So in here, make sure skeletons are turned on.
Let’s go ahead and update this marker set so we can see our marker sticks and colors. I’m going to select the chest and turn this folloow selected on. Let’s
go to right about here around 653 frames, somewhere around
there. And you’ll see that the skeleton isn’t quite solving right and
this can sometimes happen with a skeleton solve. Sometimes markers will be
occuled and the skeleton solve won’t be quite right. So there are a couple
things we can do we can go in here, hide our skeleton, we can go
in here and open the labeling pane. We can manually label all of these markers, so we could see that the left should isn’t labeled correctly and
label right here. The left pinky the left hand in we could label all these markers correctly, or we
could just label one of them and let the auto-labeler do some
more work I’m going to go and grab the left wrist make sure I am in quick label mode and I’m just
going to label that marker. That one should be the left wrist. So then we’ll go to this take and auto-label. And then, this will do a whole auto-labeling
process and now you can see that it is labeling these wrist markers a little bit better than what we had
before. So now this arm looks much better. What I’m going to do here is I’m going
to show you what happens during this whole process of
manual labeling and Motive always respects your labels. So let
me delete the markers labeles, whoopse, select our
take and delete our marker labels. Let’s go back to about the 650 frame, around there. And I know that this one is the thumb, but I am
going to label it, left wrist out. So I know that this one is suppose to be the left
wrist out, but I’m going to label this one the left writst out and we’ll see what
happens. So now you can see that the skeleton solve is incorrect, but at all times Motive is going to try it’s best to make sure that, let me turn my lablels on, that this marker right here is wrist out. Follow selected is on so we can scurb through
this take. So it’s trying its best to make sure that lable is
respected and everything else it’s going to auto-label. So
things like the waist, the feet, it’s not really effected by this
label. But a lot stuff that is apart of the arm and hand is
going to be effected by this label. And Motive is respecting this laebling and then
doing it’s best to solve the skeleton. So let me just go back one
more time and I’ll show you a little bit of manual labeling here. So we know that that is not the wrist so we can
delete that label right there. We could go in here, we could set our quick label, label that the wrist out. I know that the left pinky is going to be right here. The left hand in I think is already correctly labeled right here Yeah, we can just label the left hand in anyway. The left thumb is right here. The left index is going to be up here and then, what do I have left, the left hand out is
going to be right there and then the left in is going to be right here.
Alright so the left hand out was on over on the other side. So you can
see that was kind of a manual labeling process and it took a little longer but now Motive is going to respect all of these
manual labeles we have just done during the auto-labeling
process. And now you can see that durring this take the skeleton is solving with all of our maunally labeled markers. and this happens from time to time on skeleton
solves, but just to let you know I did kind of cheated here. I
did label one of these wrist markers up here to begin with
and this skeleton actually solves fine if we go and delete the marker labels and then we just let the auto labeler run by itself its going to label this skeleton just fine. So you can see that the skeleton is labeled fine,
but if you want to play around with these auto-labeling
features some more I’ll show you what I did to set ip this take. I just went to my labeling pane
and then I took the left wrist out and I labeled it somewhere whacky, like up by the shoulder here. And now we have a really weird solver here and you can see it snapped to that
solve. So you could label the left wrist out, I’m going to turn
my marker labels off, so you could label the left wrist
out somewhere weird, like right here and it will give you a very odd skeleton solve. And then when you do an auto-
label process it’s going to keep that label right there and you’ll get a very
odd skeleton solve and then you play around with manual
labeling or labeling one marker and seeing how the skeleton solve reacts. Alright
that is going to be it for this video. I hope you enjoyed the skeleton
tutorial number one. Look for the other tutorial videos on our website as well as our playlist on youtube and vimeo. Thank you everyone for watching and as
always, thank you for choosing optitrack.
