Reference image URLMust be a publicly accessible link
​
video_url
string
required

The server probes the actual duration of video_url. Minimum is 3 seconds; maximum is determined by character_orientation.
​
keep_original_sound
string
default:"yes"
Whether to retain the original audio track from the reference videoOptions:
  • yes: Keep original audio (default)
  • no: Do not keep original audio
​
character_orientation

Generation modeOptions:
  • std: Standard mode (balanced speed and quality)
  • pro: High-quality mode (higher latency)
​
