Artifacts and unnatural results typically stem from low-quality source materials, extreme facial angles, or mismatched lighting between the swap image and target video. To troubleshoot, first ensure your swap image is high-resolution, front-facing, and well-lit. Next, verify that the target video has stable footage with the face clearly visible throughout—avoid shaky camera work or rapid head movements. If issues persist, try adjusting your prompt to include specific guidance like "smooth blending" or "natural skin texture." For comparison, run the same inputs through
AI Face Swap Video to see if a different model architecture produces better results. JAI Portal's side-by-side comparison tool lets you evaluate multiple outputs before committing credits to large-scale production.
