To create a jittery text animation effect in After Effects, the creator made three compositions called "Main", "Displacement Map", and "Text". In the "Displacement Map" composition, they applied fractal noise to a solid layer to generate random movement. This layer was then used as the displacement map for the text layer in the "Main" composition, causing the text to jitter subtly with the noise. Additional settings were adjusted to achieve the desired visual effect.

1. TEXT ANIMATION

3. To create this text animation I used After
Effects as it has the effects and features that I
needed to create the jittery text animation. I
then created three compositions called ‘Main’,
‘Displacement Map’ and ‘Text’. I then added
the Main composition to my timeline and
added the others to this composition.

4. Firstly, I added a
solid layer to the
displacement
map
composition and
applied the
fractal noise
effect.
I changed the
setting slightly
for the effect so
that the fractal
type was
‘Dynamic’ and
increased the
brightness and
contrast.
Then I clicked
on ‘Random
Seed’ and set the
time to *10 as I
found this to be
the right amount
for the jittery
effect that I
wanted.

5. In the text composition I used the text tool to type out the text that I wanted to have
in my video. I changed the font and sizes to match those which I have used before in
my music video so create continuity.

6. I then changed
the
displacement
map layer to the
displacement
map and it to
Luminance and
3.0 for max
displacement so
that the text
would move
slightly less as I
only wanted a
subtle effect.
Next, I added a
‘Displacement
Map’ effect to
the text layer in
the main
composition.
Lastly, I turned
off the visibility
for the
displacement
map layer so
that the text and
black
background
were visible.
