Greyscale Gorilla answers "a question asking how to fly a camera around in After Effects and land on full frame video. To make these moves land on pixel-perfect, full-frame video can be tricky. This technique should help keep your camera moves and transitions accurate and ready for a perfect edit."
GG commenter Galen Frazer says VideoCopilot's Sure Target preset (with tutorial) "allows you to set up multiple targets and easily keyframe in between them. Also allows for shake/easing/auto rotate as well. BUT… it won’t give you the 'pixel perfect' move shown here without tweaking anchor points, etc."
