## What EffectCraft is
EffectCraft is for animated titles, motion graphics and compositing work: the kind of thing

text, footage, other compositions), animate their properties with keyframes, stack effects on
them and render the result.
-The aim is to feel familiar to anyone who has used After Effects, with the same panels (Project,
