PixVerse V6

PixVerse · ~1.5 min

from $0.037per second

PixVerse V6: 1–15 second clips with sound from a description, a photo, two frames or up to 7 reference photos. 360p to 1080p.

PixVerse V6 is a PixVerse video model with cinematic camera work and realistic motion. 1 to 15 second clips: from a description, from a photo (the first frame), a transition between the first and last frame (5 or 8 seconds) or from 1–7 reference photos.

360p, 540p, 720p or 1080p. Sound is made together with the video (cheaper without it). You pay per second of the clip.

One model, pixverse-v6 · ~1.5 min. The result follows the input fields (prompt, frames, references, video_mode, duration) — there are no separate «animate / edit» endpoints.

Features

generate_audio — audio in the clip

Price

Resolution	Price per second
360p	$0.037
540p	$0.047
720p	$0.063
1080p	$0.12

Price = per-second price × clip length, rounded up to $0.001. Charged when the task is created and fully refunded if it fails.
Sound is on by default; generate_audio: false is cheaper. First + last frame make a transition, 5 or 8 s only. image_urls (1–7 photos) are references; you can mention "photo 2" in the prompt. aspect_ratio applies to text and references; with a frame the shape follows the photo.

Media limits

  "data": null,
  "error": "rate_limit_error"
}

500

{
  "code": 500,
