What I want to do is simple conceptually, but I am just not having success with actually doing it.
I am creating a short video snippet in After Effects, as part of a larger presentation. The video is supposed to begin with a blinking light under the title, which then transitions, with a sound effect, to the video itself.
I've worked out the sound effect, the transition, and all of the other stuff - I just don't know how to animate a blinking light. There must be a way to automate turning the opacity on and off - but all of the tutorials I've found date from several years ago at the earliest and presuppose a working knowledge of After Effects that is more in-depth than what I have.
Can someone point me in the right direction? Preferably with explicit steps!
