Seamless Face Overlay Game Video

I’m halfway through creating a four-minute role-playing game montage in CapCut and need help perfecting one key effect: replacing the hero’s face with mine so it blends naturally throughout the entire clip. The straightforward shots are done, but any time the camera shakes or the character turns, my current tracking slips, breaks alignment, or loses realism.

Here’s exactly what I need from you:
• Stabilise and motion-track every problematic scene so my face stays locked to the character, even during rapid moves or camera shake.
• Match the game’s lighting, colour grade, and texture so the overlay looks as realistic as the native footage—no obvious cut-outs or cartoonish edges.
• Deliver a polished, export-ready 1080p (or higher) video around four minutes long, plus the editable project file (CapCut or your preferred software) so I can tweak minor details later.
• Briefly document your workflow or key settings so I can replicate small fixes on future clips.

If you live and breathe tools like After Effects, Mocha, CapCut’s keyframe tracker, or similar, this should be a smooth ride. Show me a short sample or link to any face-replacement or VFX tracking work you’ve done, and let’s wrap this up.
