BFS-Best-Face-Swap-Video

ltx-2.3/...

Analyze this composite video.

The video contains:
1. a side chroma-key panel with a reference face image
2. a main performance video showing the body, clothing, movement, hand actions, objects, framing, and environment

Your task is to extract:
- the target face identity from the side panel
- the performance/action from the main video

Critical rules:
- The side-panel face is the only valid source for identity traits and head-level accessories.
- Ignore the visible face and head appearance in the main video completely.
- Do not describe any face, hair, hairstyle, hair color, eye color, makeup, facial features, facial expression, attractiveness, headwear, hood, hat, or accessories from the main video.
- In the ACTION section, describe the performer only as "a person" and focus only on body movement, clothing, hand actions, objects, framing, and environment.
- Do not mention the chroma panel, green background, split layout, or editing structure.
- Be factual and non-creative.
- Do not guess uncertain details. If a detail is not clearly visible, omit it.

Return exactly in this format:

FACE:
A brief but detailed objective identity description from the side-panel face only. Include, when clearly visible: apparent gender, apparent ethnicity, skin tone or complexion, approximate age range, head shape, hair or baldness pattern, hair color, eye color, facial hair, visible skin details, headwear or head covering, visible facial accessories, and any especially distinctive facial trait. Prioritize the eyes when they are a strong defining feature.

ACTION:
A concise performance description from the main video. Include only: visible clothing, body position, movement, hand actions, objects being shown or handled, camera-facing behavior, framing, and environment. Do not include any face or head appearance from the main video.

Good example:
FACE:
Female, fair skin, approximately 20-30 years old, oval head shape, long wavy vivid blue-violet hair, bright golden-amber eyes with dark defined pupils, no facial hair, smooth skin, and pink flower hair accessories as a distinctive head adornment.

ACTION:
A person in a dark top faces the camera indoors, holds a package of false eyelashes close to the lens, peels one lash from the backing, brings it near the eye area, and examines it while making small hand movements.

Bad example:
ACTION:
A person with long curly blonde braids holds a pair of false eyelashes...
