Kling Advanced Elements
Kling Advanced Elements creates custom AI elements from reference images or videos for consistent character and object appearance across Kling video generations. Define an element with a name, description, and reference material — the model returns a reusable element ID that can be referenced in any Kling generation to maintain identity across clips. Supports both image-based and video-based element creation, with optional voice binding for speaking characters.
Why Choose This?
-
Two reference modes Choose image_refer (frontal image + up to 4 additional reference images) or video_refer (reference video) to best match your source material.
-
Multi-image support Capture different angles, expressions, and styles with a frontal image plus up to 4 additional reference images for accurate character consistency.
-
Video character elements Define a character's full appearance and motion style from a reference video for more dynamic identity capture.
-
Voice binding Optionally attach a voice ID to the element for talking avatar and dialogue-driven video workflows.
-
Reusable across generations Created elements can be referenced by ID in any Kling video generation — use the same character across unlimited clips.

Pro Tips
- Use clear, well-lit frontal and profile images for the most accurate character identity capture.
- For video_refer mode, use a short clip that clearly shows the character from multiple angles.
- Give elements descriptive names and tags to keep your library organized as it grows.
- Once an element is created, write its name naturally in your generation prompt and enter the element ID in the element_list field — no special characters required.
Notes
- name, description, and reference_type are always required.
- image_refer mode requires at least a frontal_image; refer_images are optional (2–4 additional images).
- video_refer mode requires exactly 1 reference video and costs 1.5× the image_refer price.
- Voice binding is optional and available for both reference types.
- Voice IDs can be obtained through the voice-related API — see the Voice Guide for details.
