After Effects – Infographic Expression Tutorial
From Bryan Clark: Today I’ll share an expression I wrote to improve my workflow, which comes in handy any time I need to populate the screen with a large number of elements (e.g. filling the frame with photos, or animating info graphics, etc).
By laying the elements out first in Photoshop, then using the ValueAtTime & delay expressions, I have much greater flexibility for tweaks & future revisions than using standard methods (like the standard Sequence Layers function).
I’ll describe the normal method & show the problems therein; then explain the expression, what it means, and how to apply it.
