All language subtitles for Nuke Compositing for 3D Artists week 2 - Classroom - CG Master Academy_3

now that we've used the tracker note to um

solve for a couple track points

now we could move along to using that tracking data to

either stabilize or match move an image

um so back in our tracker node

if we look into the next tab for um

in the next tab of

in the properties for it

um this is the settings tab for it

so there isn't normally a whole lot you need to um

deal with in this section but uh

it does give you a couple options of

if you're having an image that

for example has changes in luminance

um you could check this box here and um

also change the error settings for it too

so you could change the tolerance level forward

to help your tracker um

stick to a point better

um the other uh

options in here too that

um sometimes can be handy to adjust is

um for example

if you no longer want to see your uh

zoom window over here

you could change this show's zoom window to either

never and that gets rid of it

or you could always just leave it on track

move or when tracking

so it only appears when you're tracking

and then once you've solved

uh it doesn't show you that zoom window anymore

the other thing too is if you have a lot of

manual keyframes you've put in here

so your hand tracking a point slipped off and you

needed to readjust that point

you'll end up with a lot of keyframe displays over here

and Nuclex to

Nuclex to process goes downstream

and that could slow down your um your comps

so what you could do under this

uh keyframe tracking option here

you could under this keyframe display

you could set this to none

and it'll never show you that keyframe display anymore

so that's a handy thing to to set um

after you've got your track solved

and you don't want it to

process the display anymore or process that keyframe

it doesn't affect what the trackers doing at all

it just takes away the display for it

so that's a handy one to keep in mind

but for right now

I'll just leave it to scroll

um to near a single line only

um and we can move on to the next tab on this thing

which is the transform tab

this is the um main

tab that we will be using to do

our match moves and stabilizations

so to begin with

what we could do is

this transform option by default itself to none

because we were solving for a track

but if you wanted to use this track to

stabilize your image

in this pulldown

you see you have the option to stabilize

you have the option to match move

as well as remove and add jitter

to your image

so uh one way to test to make sure our track is

working pretty well is always to set this to stabilize

and check uh

flip a car are uh

are played to see if it's stabilizing

so we'll do that for right now

I'm gonna set this to stabilize

and um we could

view this tracker now

and if we press play

you'll see

your you'll see our image is nice and locked

you could see this outside bounding box

you're seeing

you're seeing what the

what the image was originally doing

it was panning

but our our trackers doing a good job of stabilizing it

so that's what the stabilization option does

so in this case

if we wanted to

add something in here

we could definitely add it and then reapply

the move back to it

so that's pretty good so far

it's doing a pretty good job

and keep in mind right now this is just using track 1

so if you wanted it to average

the other two tracks that we've done

if we set um

let's go to frame like this

if we set track here

and on and check these

transform options in track 2 and track 3

and we flipbook now

you could see it's gonna be using

all three of these tracks to stabilize

which isn't a bad thing in this case

because we have a track point that's

really close to camera

and we have two points that are in the background

so it's a good way to average between um

between the

the three points

so that you know

a point up here would have more parallax than

points back here

so as you can see

we've got a pretty good

stabilization going on right now

and if we had rotations as well

you would see that too so um

based on what we've selected here

you could see

our track is set to zero on our face first frames

and as we move on

you could see these x

y values as it's

as it's trying to stabilize here
