Features

PixVerse v5.5 — Transition

PixVerse v5.5 Transition morphs one image into another with smooth, cinematic motion guided by a short prompt. Give it a start image, an end image, and a description of the transformation—the model handles the in-between frames while you control aspect ratio, duration (5s / 8s / 10s), and resolution (360p–1080p).

✨ Highlights

• Prompt-guided image-to-image morphing – change outfit, lighting, era, mood, or environment between two stills.
• Story-friendly formats – aspect ratios for feeds, stories, and widescreen: 16:9, 1:1, 4:3, 3:4, 9:16.
• Resolution choices – render at 360p, 540p, 720p, or 1080p depending on speed and quality needs.
• Identity & framing aware – keeps subject pose and composition stable while the transformation unfolds.

Perfect for before-and-after reveals, campaign creatives, character “power-up” shots, and scroll-stopping social posts.

🧩 Parameters

• prompt* – Short description of how the scene should change (e.g. “Casual student gradually transforms into cyberpunk hero, neon city lights appear, dramatic lighting”).

• image* – Start frame (URL or upload).

• end_image* – Target frame (URL or upload).

• aspect_ratio – One of 16:9, 1:1, 4:3, 3:4, 9:16.

• duration – 5, 8, or 10 seconds.

• resolution – 360p, 540p, 720p, or 1080p.

• thinking_type – Prompt reasoning enhancement:

  • enabled: add extra system reasoning/optimisation for complex prompts.
  • disabled: use the raw prompt as-is.
  • auto (default): let the model decide.

• negative_prompt (optional) – Things to avoid (e.g. “distortion, double face, text, watermark”).

• seed (optional) – Leave blank for random, or set a fixed integer for reproducible transitions.

🚀 How to Use

1. Upload image and end_image – use shots with similar framing for the cleanest morph.
2. Write the prompt – focus on mood, style, and transformation rather than long scene descriptions.
3. Choose aspect_ratio, duration, and resolution to match your target platform.
4. (Optional) Set thinking_type = enabled for more complex story prompts, and add a negative_prompt if you want to suppress artifacts.
5. (Optional) Set a seed if you need the same result again later.
6. Click Run, then preview and download your transition clip.

💰 Pricing

Billed per second, based on duration and resolution:

*Longer clips (10s) follow the same per-second logic.

🧠 Tips

• Use start/end images with similar camera angle and framing to minimise warping.
• Keep prompts short and focused: one transformation + one mood usually works better than a laundry list.
• For storyboards and quick previews, use 360p/540p; for final export into an edit timeline, use 720p or 1080p.
• If faces or hands look unstable, tighten the crop or simplify the transformation described in the prompt.
