Create a transformation transition from the casual version of the character in the first image to the armored sci-fi hero in the second image. Keep the face, pose and camera framing consistent as holographic shards, light streaks and metallic plates swirl around the body, gradually replacing the hoodie and jeans with the glowing armor. Realistic cinematic look, cool blue and white lights, rising synth sound and a sharp "whoosh" at the peak of the morph, no dialogue.

Smoothly transition from the bright daytime city skyline in the first image to the neon night skyline in the second image. Keep the buildings and perspective stable while the light slowly shifts from sunny blue to deep night, windows and neon signs gradually turning on. Add a gentle forward camera push, timelapse feeling, realistic cinematic style with soft ambient city noise and a subtle whoosh during the change, no voiceover.

Smoothly transition from the daytime natural forest in the first image to the glowing enchanted forest in the second image. Keep the camera in the same wide position as daylight slowly dims, colors shift to deep blue and violet, and bioluminescent plants, mushrooms and fireflies gradually light up along the path. Add a slow dolly forward along the path, with subtle wind and birds fading into soft magical chimes and ambient pads, no dialogue.

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

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

💰 Pricing

Billed per second, based on duration and resolution:

Resolution	5s clip (total)	8s clip (total)	Price per second*
360p	$0.15	$0.30	$0.03
540p	$0.15	$0.30	$0.03
720p	$0.20	$0.40	$0.04–0.05
1080p	$0.40	$0.80	$0.08–0.10

*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.

Pixverse v5.5 Transition API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/pixverse/pixverse-v5.5-transition with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Pixverse v5.5 Transition below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/pixverse/pixverse-v5.5-transition" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "image": "https://example.com/your-input.jpg",
    "aspect_ratio": "16:9",

    "resolution": "540p",
    "thinking_type": "auto",
    "negative_prompt": "blurry, low quality, distorted",
    "seed": 0
}'

# Response includes a prediction id. Poll for the result:
curl -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY"

# When status is "completed", read the output from data.outputs[0].

Node.js example

// npm install wavespeed
const WaveSpeed = require('wavespeed');

const client = new WaveSpeed(); // reads WAVESPEED_API_KEY from env

const result = await client.run("pixverse/pixverse-v5.5-transition", {

Pixverse v5.5 Transition API — Frequently asked questions

What is the Pixverse v5.5 Transition API?

Pixverse v5.5 Transition is a Pixverse model for video generation from images, exposed as a REST API on WaveSpeedAI. Create smooth morph transitions between two images into 5s, 8s or 10s videos at 360p, 540p, 720p, or 1080p—perfect for logo reveals, before-and-after shots, and social posts. Ready-to-use REST inference API, best performance, no cold starts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Pixverse v5.5 Transition API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/pixverse/pixverse-pixverse-v5.5-transition.

How much does Pixverse v5.5 Transition cost per run?

Pixverse v5.5 Transition starts at $0.45 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Pixverse v5.5 Transition accept?

Key inputs: `prompt`, `image`, `aspect_ratio`, `resolution`, `duration`, `seed`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/pixverse/pixverse-pixverse-v5.5-transition.

How long does Pixverse v5.5 Transition take to generate?

Average end-to-end generation time on WaveSpeedAI is around 74 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Pixverse v5.5 Transition outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (Pixverse). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
