Adobe Group meeting – expressions in after effects

Next Event – 17th March 2012 @ 7.30pm

Adobe groups March 17th  – After Effects Expressions with Dariusz Dziala

Expressions help to simplify post-production work in After Effects by replacing big numbers of keyframes with short lines of code. Expressions can be applied to object properties for example they can be applied to position, scale, opacity, rotation of layer, text, mask, light, camera. They can also be applied to any animatable property of effects.

 

The code used is simple and easy to learn or find. After Effects offers a lot of pre-defined expressions for different purposes.

 

Dariusz will use some of his  video work to illustrate how he use expressions to work faster and how to use expressions in a creative way. The video is on his website if you want to have a preview (www.dariusz.tv),

 

The expressions in his video  are used to synchronise music with video properties (position, scale etc.) and other visual effects (hue, saturation, brightness etc). The aim is to improve the dynamics of the visuals and to give more punch to the overall feel about it.

 

Plan of the presentation:

 

1. Projection of the video

2. Intro about expressions – theory – the basics – what they are and how they work

3. Simple expressions in practice – how to achieve within a few minutes results like: 

– ticking clock

– flying butterfly

– shaking screen

– flickering light

by using expressions only, no keyframes.

4. Expressions in my video:

– applying expressions to effects

– synchronising visual effects with audio

5. Wrapping up and few tips on where to look for more information about expressions (books, tutorial sites etc.)

6. Questions/answers.
