Kling Video Generation model should include option to upload reference video to control motion.

As a video editor/creative director, I am requesting the ability to upload a reference video (driving video) to control the motion of the generated AI output in the Kling model. 

• The Goal: I want to upload a static character image (or image-to-video) and a separate video file that dictates the motion (e.g., a person walking, dancing, or gesturing).
   
• The Feature Needed: A dedicated "Motion Reference" upload slot that extracts body dynamics, hand gestures, and facial expressions from the reference video and applies them to the generated character, similar to a "motion transfer" or simplified motion capture workflow.
   
• Why this matters: Currently, text-to-video prompting is too imprecise for complex choreography or specific performance acting. A motion reference option would enable:
  1. Precise, believable physical movement.
  2. Consistent performance across multiple clips.
  3. A significant reduction in prompt editing time. 

Workflow Example:

1. Upload Character Image A.
2. Upload Reference Video B (person walking).
3. Model generates Character A walking exactly like Video B.
