Pixverse Pixverse V6 Transition API Documentation

Playground

PixVerse V6 Transition creates smooth AI-generated video transitions between a start image and an optional end image. Supports 360p to 1080p resolutions, 1-15 second duration, multiple aspect ratios, optional audio generation, and multi-clip mode. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

PixVerse V6 Transition generates a smooth, cinematic video transition between two images. Upload a start frame and an end frame, describe the transformation, and the model produces a natural, motion-consistent clip that flows seamlessly from one scene to the other — with optional style control, multi-clip generation, and synchronized audio.

Why Choose This?

• Start-to-end frame transitions Generates a coherent video that naturally bridges two distinct images with smooth, believable motion.

• Prompt-guided transformation Describe how the transition should unfold — wardrobe changes, environmental shifts, camera movements, and more.

• Multi-clip generation Enable generate_multi_clip_switch to produce dynamic transitions with varied camera angles and cuts.

• Style control Apply a specific visual style (e.g. cyberpunk, cinematic, anime) to the transition for creative output.

• Optional audio generation Enable generate_audio_switch to produce synchronized ambient sound alongside the transition.

• Thinking mode Prompt optimization mode for more nuanced or complex transition descriptions.

Parameters

How to Use

1. Upload your start image — provide the opening frame of the transition.
2. Write your prompt — describe how the transition should unfold (e.g. “Change the model’s clothes for a smooth transition.”).
3. Upload end image (optional) — provide the target frame to transition toward.
4. Select aspect ratio — choose the format that fits your target platform.
5. Select resolution — 360p for drafts, 720p for standard output, 1080p for final production.
6. Set duration — choose your desired clip length in seconds.
7. Enable thinking_type (optional) — activate prompt optimization for complex transitions.
8. Enable audio (optional) — check generate_audio_switch to generate synchronized sound.
9. Enable multi-clip (optional) — check generate_multi_clip_switch for dynamic camera changes.
10. Set style (optional) — apply a visual style to the transition.
11. Add negative prompt (optional) — specify elements you want to avoid.
12. Set seed (optional) — fix the seed for reproducible results.
13. Submit — generate, preview, and download your transition video.

Pricing

Billing Rules

• Billing is calculated per second of video generated
• Audio generation increases cost per second at each resolution tier
• Examples: 8s at 720p (no audio) = $0.36 — 8s at 720p (with audio) = $0.48

Best Use Cases

• Fashion & Apparel — Create smooth outfit or style change transitions for social content and lookbooks.
• Social Media Content — Generate eye-catching before-and-after transition clips for Reels and TikTok.
• Marketing & Advertising — Transition between product states, environments, or campaign visuals.
• Creative Storytelling — Bridge two scenes or time periods with a cinematic, motioned transition.
• Music Video & Art — Use style presets and multi-clip generation for visually rich transitions.

Pro Tips

• Provide both a start and end image for the most controlled and accurate transition output.
• Be specific in your prompt about what changes between the two frames — clothing, location, lighting, or time of day.
• Use multi-clip generation for transitions that benefit from dynamic camera angles and cuts.
• Use 360p at short durations to test your transition concept before committing to a high-resolution render.
• Fix the seed once you find a result you like to iterate consistently across duration and style changes.

Notes

• Both prompt and image are required fields; all other parameters are optional.
• Ensure image URLs are publicly accessible if using links rather than direct uploads.
• Please follow PixVerse’s content usage policies when crafting prompts.
