Pixverse v6 Video-Extend API by PIXVERSE

pixverse/v6/video-extend
Video-extend

Pixverse v6 Video Extend model. High-quality video generation from image prompts.

PixVerse V6 Video Extend

PixVerse V6 Video Extend lets you seamlessly extend any existing video beyond its original length. Upload a source video, describe how the scene should continue, and V6 generates a smooth, coherent extension that picks up naturally from the last frame.

Why Choose This?

  • Seamless continuation Extend any video with natural motion that flows from the original ending.

  • Prompt-guided extension Describe exactly how the scene should evolve after the cut point.

  • High resolution output Extend videos in 360p, 540p, 720p, or 1080p quality.

  • Flexible duration Add 1 to 15 seconds of new content to your video.

  • Reproducible results Use a seed value to reproduce or iterate on extensions.

How to Use

  1. Prepare your source video — upload the video and obtain a public URL, or use a previously generated PixVerse video.
  2. Write your prompt — describe the motion, action, or scene development after the current ending.
  3. Set quality — match the resolution of your source video for consistent output.
  4. Set duration — choose how many seconds to add (1-15).
  5. Set seed (optional) — fix a seed to reproduce the same extension result.
  6. Run — submit and download your extended video.

Best Use Cases

  • Short-form Content — Extend social media clips that ended too soon.
  • Cinematic Scenes — Prolong a cinematic shot for more dramatic effect.
  • Product Videos — Add extra seconds to showcase more product detail.
  • Story Continuations — Let a narrative scene play out further than the original.
  • Looping Content — Generate additional footage to create longer loop-ready clips.

Pro Tips

  • Match the quality setting to your source video resolution for the best visual consistency.
  • Be specific in the prompt about what should happen next — vague prompts produce generic continuations.
  • Use short extensions (1-3s) for subtle continuations and longer ones (8-15s) for significant scene developments.
  • Fix a seed value when iterating on prompt wording so you can compare continuations fairly.
  • Ensure the source video URL is publicly accessible before submitting.
