The model captures subtle distinguishing details: earrings, hairstyles, clothing colors, body positioning, scene lighting. Your description can be brief or detailed. The result stays accurate either way.

Frequently Asked Questions about AI Video Change Character
-
1. Can I target a specific timestamp instead of replacing characters throughout the entire video?
Yes. Reference the exact time in your prompt — "replace the character at 0:23" — and the AI applies the swap only at that moment. Everything before and after remains unchanged.
-
2. What if the AI swaps the wrong person when multiple similar characters appear on screen?
Add more distinguishing details. Write "replace the woman on the left wearing a black jacket" instead of just "replace the woman." The more visual specifics you include, the more accurately the AI targets the correct person.
-
3. Can I keep the original person's body movements while only swapping the face?
Yes. Write "keep the original body and movements, only change the face" in your prompt. The AI preserves the performance while applying the new facial features seamlessly.
-
4. What should I do if the lighting in my video is uneven or mixed?
Include the lighting description in your prompt — "this scene has strong side lighting from the right" — and the AI adjusts the replaced face to match existing shadows and exposure naturally.
-
5. My video has mixed lighting — some areas bright, others dark. Will the swap look natural?
Mention the lighting setup in your prompt — "uneven lighting, brighter on the left side" — and the AI matches the replaced face to the actual lighting conditions in each frame.
