Notes

PixVerse C1 is the cinematic tier, tuned for physically grounded character motion, action choreography and effects work, with automatic storyboarding from the prompt.

Modes

  • t2v: text to video.
  • i2v: animate a single image.
  • transition: interpolate between a first-frame and a last-frame image.
  • reference: combine up to 7 reference images, including multi-panel storyboard frames.

Output

  • 360p, 540p, 720p and 1080p, 1 to 15 seconds.
  • Aspect ratios 16:9, 4:3, 1:1, 3:4, 9:16, 2:3, 3:2 and 21:9 on text-to-video and reference modes. Image-driven modes follow the source image.
  • Set generate_audio_switch to true for native synchronized audio.

Billing

  • Billed per second of generated video at the rate for the output resolution, with a higher rate when audio is on.

Input limits

  • Images: PNG, JPEG or WebP, up to 20MB and 10000px on the long edge.

C1 does not support clip extension. Use PixVerse V6 for that.
