All language subtitles for 9. Dealing with Occlusions when tracking Color Tab Kolder Creat

So this

is a bit more of an advanced
tracking lesson within the colored tab.

I'm going to be showing you guys
how we can get an accurate track

on this clip,
even though there are occlusions in it.

Occlusions are basically just any object
that get in the way of the camera

and the subject
that you're trying to track.

So in this case,
this beam right here is an occlusion.

And we also got an occlusion
right here too.

So it happens twice.

Now, normally,
if we tried to track our clip forward,

if we tried to track this window forwards
here, what would happen is

it would freak out.

As soon as we get to this occlusion,

because all of our tracking data
is now gone.

Right.

There's no more tracking data
in this area.

So it's going to freak out
and not know what to do.

So in this lesson,

I want to show you guys
how we can fix these types of situations.

So let's navigate to a frame
where we can see our entire subject

and let's make this
window a bit smaller here.

Cool.

That looks good to me.

Maybe I'll rotated a bit
and let's just track forwards

and see what happens here.

We can see or stop it.

The mask decided

to follow that beam,
so we lost the tracking points

that were around me, and it decided
to get pushed by this beam over here.

So obviously that's not what we want.

So what we want to do
is navigate to the point

right before the beam
gets in the way of our track.

So what we're going to want to do
down here in our tracker is go to frame.

And at this point
we're going to want to add a keyframe

so we can add a keyframe here
just by moving our window a tiny bit.

And what we going want to do

now is draw a bounding box
around the rest of our track over here.

And we can connect these three dots
in the top

right and select clear selected
track data.

That way kind of resets it.

Now we're going to move our play head
forwards a little bit

so that we're past this occlusion,
and then we're going

to want to move this window
a tiny bit again.

And then from here
we can track forwards again.

So that looks good.

Now let's go back to
where we started over here.

So from this point, and let's start
tracking backwards and see what happens.

So let's click
that track backwards button.

Oh, and it looks like it

kind of almost worked, but it didn't work
well enough to continue tracking.

So let's go back to the point
just before the track messes up.

So right here.

This looks good
since we're in the frame option here.

Let's just move this
a tiny bit to add a keyframe here.

And let's move backwards now,
and we'll add another keyframe right here.

And we're going to clear
all of the tracking data

before this point right here.

So we'll do the same thing.

Will draw a bounding box around this area
right here.

And we'll go to those three dots up here.

Clear selected track data.

We can see that
we've removed that keyframe over here.

And now from this point,
we can continue tracking backwards.

And it looks
like it latched on to that beam again.

So let's go back over here.

Let's clear this track data again,

clear selected track data.

Let's move one frame over here
and let's move this window a little bit.

I think
because we were still close to the beam.

The beam was still within our window
over here.

I guess it latched onto it
and kind of messed things up.

So we'll go to this point here
and now we can track backwards.

And that looks pretty good to me.

It's doing a pretty decent job. Awesome.

And just like that, we've managed
to track this window to our subject here,

even though there's two occlusions
in this one shot

and we managed
to get a pretty good track here.

So if we wanted to make
any kind of specific changes

to just our subject here,
we can do that freely because we

have a window that's tracked to him
throughout the entire scene.

Now, in this situation,

I don't exactly know
what we would do here,

but if we wanted to make any kind
of changes to the inside of this window.

So maybe like,

I don't know,

something like temperature
or tint or whatever, we can do that.

And we know that we have a solid track.

So this is a really cool feature of the
tracker that's built into the color tab.

So being able to go into our tracker
over here and get visual data

with this graph over here and select parts
of our track and delete them is huge.

This is a feature that I'm not used

to having in other programs
and it just shows me

how forward Thinking DaVinci is
when it comes to things like this.

I love the fact that we can go in
and visually see where our track messes

up in this graph area over here
and make the manual changes that we need,

but still continue to use the tracker
for any points that we want to.

So it's like we basically combined
the auto tracking with manual

tracking to get the absolute best result
possible in this situation.

I hope you guys enjoyed this
lesson. I'll see you in the next one.
