Lately, I’ve realized that I’ve never really posted the expressions that I use most often. Partially, this has been be trying to not create an overlap between freebies posted and, and not so free things posted elsewhere. But, know I’ve got a handle on that, so I’d like to start posting, what I consider, the most usable expressions.

By the way, I keep my expressions organized in a Widget called “Bit Memo”, this way my expressions are a button click away.

This expression here is a automatic auto fade in/out expression. Place it in opacity, and the layer will fade in the number of frames specified at the beginning. I use this a LOT. It’s very handy, especially considering the steps it takes to create a dissolve in AE.

AutoFade i/o Preset

Or if you prefer, here is the code:

transition = 30; // transition time in frames
tSecs = transition / ( 1 / thisComp.frameDuration);
