# Kling - V2.5 Turbo Image to Video Pro
> Transform images into dynamic videos powered by Kling's advanced AI model
## Query Task Status
After submitting a task, use the unified query endpoint to check progress and retrieve results:
Learn how to query task status and retrieve generation results
For production use, we recommend using the `callBackUrl` parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.

The model name to use for generation. Required field.
- Must be `kling/v2-5-turbo-image-to-video-pro` for this
endpoint

callBackUrl:
type: string

description: >-
The URL to receive generation task completion updates.
Optional but recommended for production use.
- System will POST task status and results to this URL when
generation completes
- Callback includes generated content URLs and task
information
- Your callback endpoint should accept POST requests with
JSON payload containing results
- Alternatively, use the Get Task Details endpoint to poll
task status
- To ensure callback security, see [Webhook Verification
Guide](/common-api/webhook-verification) for signature
verification implementation

Text description for the video generation (Max length:
2500 characters)
type: string
maxLength: 2500
example: >-
Astronaut instantly teleports through a glowing magical
wooden door. Handheld tracking, camera stays 5–10 meters
above and behind, smooth third-person chase.
Hyper-realistic base, each scene with distinct art
style, instant scene flashes with bright portal glow,
high detail, 8K, epic orchestral undertones. High-frame
interpolation for smooth motion and sharp instant
transitions. Close-up: astronaut in white suit falls
rapidly through glowing portal underfoot.
First transition: LEGO Alps, high-saturation daylight,
snowy peaks and valleys below, astronaut falls, next
portal opens.
Second transition: Amazon rainforest, dense canopy and
rivers below, astronaut falls, next portal opens.
Third transition: Ancient Egypt, Giza pyramids in mural
style, desert and Nile below, astronaut falls, next
portal opens.
Fourth transition: abstract black-and-white ink style,
Chinese Great Wall below, astronaut falls, final portal
opens.
Fifth transition: New York night, realistic dark
skyline, glowing city lights, Empire State Building,
astronaut hovers elegantly. Camera maintains constant
distance, slight orbit, smooth third-person tracking
throughout. Each portal transition is a sharp flash,
emphasizing speed and magical journey, abrupt style and
location shifts.
