Teach AI Face-Swap Video Creation

I want to master the entire workflow of making face-swap videos on my Windows desktop without breaking the bank. The ideal path will use a completely free or very low-cost AI tool—something along the lines of DeepFaceLab, FaceFusion, or any other desktop solution you trust that runs smoothly on Windows.

Here is what I need from you:
• Help me choose the right Windows-compatible application that is either free or extremely affordable.
• Guide me through installation and all necessary dependencies (CUDA, Python, GPUs, codecs, etc.).
• Walk me step-by-step through preparing source footage, training the model, swapping faces, and exporting the final video.
• Provide simple troubleshooting tips so I can fix common errors on my own.
• Deliver a concise cheat-sheet or screen-recorded tutorial so I can repeat the process later.

Acceptance criteria
1. I can install and launch the recommended software on my Windows PC without errors.
2. We complete at least one short face-swap video together from start to finish.
3. Your follow-up notes or recording clearly outline each stage so I can replicate it solo.

If you know an easier, faster, or even more cost-effective Windows desktop solution, feel free to propose it—I’m open to better ideas as long as they remain budget-friendly.
