Picture Frame Green-Screen Replacement

I have a short clip (under one minute) in which a person walks past a picture frame covered by a green-screen insert. I need the green area clean-keyed and replaced with my own artwork, then rendered as a 16:9 master file. You’re welcome to use either After Effects 2026 or drop back and forth between Premiere Pro 2026 and After Effects 2026 via Dynamic Link—whichever gives the cleanest edge, natural motion blur and colour match. Besides delivering the finished video, I also want to learn the workflow you use, so please record a concise screencast while you work and create a short written summary of the main steps (effects used, any masks or tracking data, export settings). Think of it as a mini-tutorial: I should be able to repeat the process on my own footage after watching and reading your material. For hand-off, I’ll need: • the final 16:9 video in ProRes or high-quality H.264 • the project files (.prproj / .aep) with all assets linked • a narrated screencast explaining the replacement process • a brief written guide (PDF, Google Doc, or similar) If you already have favourite keying plugins (Keylight, Ultra Key, Primatte, etc.) feel free to use them; just note settings in the guide. Looking forward to seeing my artwork hanging realistically on that wall—and learning how you made it happen.
