When you bought CS6, you paid a one-time fee (usually around $999 for the full version) and you owned the software forever. You didn't need an internet connection to verify your license, and you didn't pay a monthly subscription.
CS6 was designed for Sandy Bridge-era Intel CPUs (circa 2012). Run it on a modern budget laptop with an SSD and 16GB of RAM, and it flies. While modern After Effects (2024) chokes on a low-end CPU, CS6 runs buttery smooth.
Before CS6, tracking 3D camera movement required third-party plugins like The Foundry’s CameraTracker (which was excellent but expensive). CS6 democratized this by including a built-in . It analyzed footage and automatically created a 3D scene that matched the original camera move, allowing users to drop text and objects into moving video seamlessly.
