Hi Buddies...

I have attempted to play with Expression Language Menu and fallen flat. Every time I apply any expression to a solid layer or text...error message pops up.

Please let me know if there is any extensive resource that deals with this powerful section of AE. It seems to be very useful to creating explainer videos.

Thanks
Sam

Hi Samya -

As you've painfully found out, expressions aren't something you just jump in and start playing with. Because they are so powerful, you have to learn the structure first. While it's not difficult to pick up, the right resource will move you along quickly:

http://helpx.adobe.com/after-effects/using/expression-basics.html

At the top of the above help file, there are also some great links to learning resources which will move you to the intermediate stage. I would suggest working down the first page of the help, which will get you a basic grounding, then moving on to whatever level you wish. Good luck with it.

Here's another good link with some examples to pick apart, in case you work well by reverse engineering things:

Thanks Joseph for sharing helpful resources.

What I am interested in is there are a hell lot of types of expressions which are applicable in different areas with their varieties of functionalists such as layer, properties, footage, lights, camera, Math, Vector etc.

Is there any site in the know that especially deals with this.

I know the basic usage of expressions like wiggle, time, value. These are mostly the derivatives of JS strings. At the moment I am trying to find out podcasts/ videos that shows intermediate to advance level use of different expression language menu.

Please let me know if you know one such.

Thanks again.

In addition to the "basics" and "examples" documentation that Joe linked you to, there's the complete reference:

[Samya Chattopadhyay] "At the moment I am trying to find out podcasts/ videos that shows intermediate to advance level use of different expression language menu."

I'm not sure I understand.

Advanced expressions are about combining the simple building blocks in a way that helps you accomplish a specific goal.

For example, unlike wiggle() which can provide meaningful results in a single-line expression, you'll rarely get much use out of a single-line expression with dot().

What exactly is it that you want to do?

Hi Walter...

Thanks for your time and talk.

I am actually into making explainer video. Using different vectors and illustrations and applying different expressions I feel there could be amazing videos and cartoon created.

I got a feeling tapping the potentials of these menu could not only reduce time but also carve out realistic and interesting videos that looks simple and engaging.

I like to make simple and elegant explainer videos with clear message.

Thanks
Sam

[Samya Chattopadhyay] "I got a feeling tapping the potentials of these menu could not only reduce time but also carve out realistic and interesting videos that looks simple and engaging. "

I would suggest you are looking at the question backwards.

Intermediate and advanced expressions are generally written to address specific challenges. The question should not be, "What can I do with intermediate/advanced expressions?" The sky is the limit. Instead, identify things you don't want to have to do with pure keyframe animation and work backwards to figure out how to handle these tasks with expressions instead.

This is still a terrific technical resource about expressions:

http://www.jjgifford.com/expressions/

And while this is old it is *not* out-of-date.
