After Effects vs Premiere Pro: Which Should You Use?

After Effects vs Premiere Pro: Which Should You Use?

After Effects and Premiere Pro are both Adobe video tools, but they do very different things. Premiere Pro is a video editor — you cut clips, arrange them on a timeline, mix audio, and export a finished video. After Effects is a motion graphics and visual effects tool — you create animations, composite layers, and build effects that get dropped into your edit. Most professionals use both. The question isn't which one is "better" — it's which one you need for the job in front of you. This guide breaks down the real differences in features, pricing, performance, and use cases so you can make the right call.
