AI Face Replacement with Lip-Sync

I have a 20-minute talk, “Who Am I? – What Shapes Our Life” (https://youtu.be/x_Zn4ilnJrM), where my on-camera image is disappointingly low-res. I’ve already produced a crisp AI render of myself and want that version to appear every time I’m on screen—throughout the entire video—while the background and framing stay exactly as recorded.

What I need:
• Track my face in all shots and replace it with the supplied AI portrait.
• Lip movements, micro-expressions, and timing must match the original speech as closely as possible so the swap is unnoticeable.
• Keep audio, pacing, and all other visual elements intact.

Deliverables:
• Final 1080p (or higher) video with the new face seamlessly integrated.
• Project file or layered comp so I can adjust captions later if needed.

I will provide the AI image plus any reference frames the moment we start. Please outline briefly which tools or workflow you’ll use (e.g., DeepFaceLab, Runway, After Effects + tracking suite) and how long you’ll need once assets are in hand. I’m keen to begin right away.
