Why does my face swap look blurry?

Usually the source photo: low resolution, soft focus, or a face that is small in frame gives the AI too little detail to reconstruct. Use a photo of at least 1080p where the face is sharp and fills a good portion of the image.

Why does the swapped face look pasted on?

Mismatch between source and target: different lighting direction, very different head angle, or strong expression differences. The closer your source photo matches the target's angle and lighting, the more the AI's blending disappears into the scene.

What is the best source photo for a face swap?

Front-facing, eyes open, neutral-to-mild expression, even lighting without harsh shadows, no sunglasses or hair covering the face, and at least 1080p resolution. One great photo beats five mediocre ones.

Do these tips apply to video face swaps too?

Yes — video adds motion on top of the same fundamentals. A source photo that matches the target's general angle and lighting stays stable across frames; a mismatched one produces drift and shimmer. See our complete video face swap guide for the motion-specific factors.

Face Swap Quality: 9 Fixes for Blurry, Uncanny, or Mismatched Results

TL;DR

Bad face swaps are almost never random — they trace to source material. The big five: resolution too low, angle mismatch between source and target, lighting from different directions, extreme expressions, and occlusions (glasses, hair). Fix those and the same tool produces dramatically better output. Here are all nine fixes, in order of impact.

The 9 fixes, ranked by impact

Use a sharp, high-resolution source — 1080p minimum, face large in frame. Detail in = detail out.
Match head angle — a front-facing source onto a front-facing target blends invisibly; 90° mismatches never fully do.
Match lighting direction — light from the left on the source and from the right on the target forces the AI to invent shading.
Keep expressions neutral-to-mild — extreme grins or squints in the source fight the target geometry.
Remove occlusions — sunglasses, heavy hair, hands near the face all cost accuracy.
Prefer even, diffuse lighting — harsh shadows split the face into zones the blend must reconcile.
Choose targets where the face is not tiny — swapping onto a distant face magnifies every artifact.
For video: pick stable segments — trim out whip-pans and motion blur (video guide).
Iterate the source, not the settings — if a result disappoints, a better source photo fixes more than any toggle.

The one-photo rule

People collect a folder of source photos and pick at random. Do the opposite: invest in one excellent photo — front-facing, sharp, evenly lit, neutral — and reuse it everywhere. Every example above was generated with exactly that kind of source. The full how-it-works guide explains what the AI does with it.
