Today we explain how to 2D Track in NUKE.
Tracking means following a group of pixels
around from frame to frame and gathering their location on each frame.Tracking
makes it possible to gauge how much movement is taking place from frame to
frame.We can use this movement information either to cancel that movement out
by neglecting it,called STABILIZING.or to transfer that movement to another element,called MATCH-MOVING.
Lets start with a simple exercise..
We will track
a shot in order to stabilize it, meaning stopping it from moving.
you can find
the footage here:
https://youtu.be/vmAhrdHbZaU (For .mov)
1.open Nuke.
2.Change it
Global to Input.
3.Drag the
footage into nodegraph.
4.connect the
viewer.
5.Double
click on Read1.
6.Change the Read1 settings following this image.
7.Press S.Then change the Full Size Format as per your footage.
8.Now attach a Tracker node to Read1 from the Transform toolbox./Press "tab" and type TRACKER.
9.Zoom into
the Spoon handle and Press ADD TRACK. click the center of the tracker point,
where it says track1, and move it to the edge of the spoon handle.
10.Click on
the Track_to_end.
11.Press
L/Play Forward.
12. In
Tracker1’s Properties panel, click the Transform tab. Choose
Stabilize from the Transform drop-down menu.
13.Select
Tracker1 and from the Draw toolbox add a Flare node.
14.Change it
position as per candle light.
15. Copy the
following values into the corresponding properties one by one and see
what each
does. When you’re done copying, if you want you can change them to
suit your
taste:
• Radius = 0,
0, 50
• Ring Color
= 1, 0.8, 0.3
• outer
Falloff = 2.3, 2.65, 2.65
• Chroma
Spread = 0.1
• Edge
Flattening = 6
• Corners =
12
The result of
the Flare node should look a lot like this image.
16.Now use
this Flare to place three more flares in the shot. Copy Flare1 by clicking it
and pressing Ctrl-C.And paste it by clicking Ctrl-V.
Move Flare2’s position to the second candle.
Repeat
the process twice more for the other two candles.
NOW time to RENDER.
17.Click
TAB.TYPE "WRITE".And connect it with FLARE4.
18.Create
a Folder.and select this folder as your File.Then Type ####.dpx.
Change the Settings like this image.And Click
Render.
Yes.We are done....
Now The Output is here
