Lesson 12. Advanced Compositing > Create a Flickering Neon Light

Create a Flickering Neon Light

Now you’re going to take the static neon image and turn it into a nice, soft flickering sign.

1.
FileIn the frame.1-109#.iff, neon.0001.iff, and trailer.1-109#.iff files once again from the Lesson12 folder.

2.
On the Globals tab, set the timeRange to 1-109.

3.
Click the Home icon at the bottom right of the interface to sync the Time Bar to the Globals timeRange.

4.
Right-click the Glow icon in the User tab and choose Create.

5.
Connect neon clip to both inputs of Glow1.

6.
Set the glowSize to 40 and the glowBrightness to 1.2.

The neon sign would look better if you increased its saturation.

7.
From the Color tab, add a Saturation node and set it to 1.75.

The glow now looks pretty good, but the neon sign really needs to flicker, as all neon signs should.

8.
Add a Blur node from the Filter tab and a Brightness node from the Color tab.

You’re going to manually animate the Brightness and Blur parameters to create a soft flickering light, which will be sure to strain your mouse finger. Later in the lesson, you’ll learn how to accomplish the same result by inserting an expression into Brightness1’s Value parameter.

9.
Go to frame 1 and click the Keyframe toggle next to the Value parameter.

10.
Enter 0.91 for the value.

11.
At frame 3, enter 0.2.

12.
Go to frame 8 and enter 0.91.
