Join Angie Taylor for an in-depth discussion in this video Flickering light effects with wiggle, part of After Effects Expressions for Premiere Pro Editors.
- Another great use for the wiggle expression is…to create a flickering light effect.…And here, you'll see,…I have the intensity value of this light,…and what I want to do, is I want to animate that,…so that the light is changing color,…but is also flickering on and off.…So, I've applied the wiggle expression to this,…and this is the wiggle expression that's applied…via the Expression Language menu,…you go to Property, wiggle,…and it places it in exactly as it's seen on this menu.…Now, I just want to explain a few of these other elements.…
We've had a look at frequency and amplitude already.…So, I would replace this with numbers,…say, 10 and maybe 50.…So, 10 times a second,…we're going to get intensity values changing,…within a value 50 of the original value,…which favors a 100%.…(electronic music)…So, that looks quite good.…If we have a look at the graph editor,…and switch on our Post-Expression Graph button,…you can see the pattern that that makes.…So, this is what's being created by that expression.…
Now, try and keep that in your memory,…
