Character Replacement vs Face Swap: What Changes in a Bulin 47 Video?

Oct 13, 2026

Understand the difference between replacing a face and generating a new performer from a photo and motion reference.

A face swap changes facial identity within an existing performance. Generative character replacement uses a photo as a reference for a broader appearance, which can include hair, clothing and body shape, while a video reference guides the performance. The distinction matters if your goal is to keep the exact original scene.

Bulin 47 AI uses the second kind of workflow: one photo plus a prepared performance reference. The current public studio does not offer a separate face-only mode or a switch that guarantees untouched background pixels.

What each input contributes

Your photo supplies visible appearance information. A clear upper-body image gives the model more information than a tight crop of the face. The prepared video supplies a scene and a performance to follow. Instructions target the lead performer, with the intention of keeping the speaker holder and setting recognizable.

These are generation conditions, not a frame-by-frame preservation contract. The model creates new frames. Gestures can differ in timing; hair or clothes can drift; hands, foreground objects and background people can change. If an original hand crosses the performer's face, both identity and the overlap need inspection.

Decide what you actually need

If your requirement is only a new face while retaining the original body and clothes, that is a narrower task than this site's character-replacement workflow. If you want your visible hairstyle and outfit to guide a new performer, an upper-body reference is more relevant. Neither goal makes a public example proof of how every uploaded photo will behave.

If you must preserve every background detail or match each gesture to a precise beat, do not infer that guarantee from the words “motion reference.” Exact source-video editing and general reference-driven generation can have different controls. This website's current H3 workflow does not promise pixel-perfect retention.

How to judge an example

Watch the genuine homepage examples, which pair input photos with playable outputs. They include an attributed Keanu Reeves portrait and two AI-created fictional adults, without implying endorsement. Inspect the beginning, middle and end rather than one attractive frame. Compare face recognizability, hairstyle, clothing, hands and the foreground speaker holder. Listen separately: visual resemblance does not establish that the audio is original.

The current example uses MiniMax H3, a 15-second target and the provider's 768P setting; the verified encoded file is 768 × 1344. Those facts describe the displayed example and current configuration, not a success-rate guarantee.

Cost and a practical starting point

The current generation price is 100 site credits. The minimum one-time pack is 300 credits for $14.90, giving three generations at that rate. There are no free generations or subscriptions. Review the live quote before clicking Generate; a second variation is another paid task, not a free correction.

A confirmed failed or canceled task returns generation credits. A successful video that differs from your expectation is not automatically a failed task or eligible for a cash refund. See the terms.
