Pixverse v6 Video-Extend API by PIXVERSE

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.

Parameters

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.
