Kling 4.0 FAQ

What is Koor AI?

Koor AI is an independent video studio offering Kling 4.0 text-to-video, image-to-video, reference-to-video and video editing through WaveSpeedAI, alongside Kling 3.0 and other video models, with a separate page for image generation and editing. It is not the official Kling service.

Can I try Kling 4.0 for free?

Eligible new accounts receive 36 welcome credits once. A 3-second Kling 4.0 video costs 15 credits at 720p or 24 at 1080p, so the grant covers two 720p trials or one 1080p trial. The same grant covers three 3-second Kling 3.0 videos. You do not need a payment card for the trial, and the welcome grant does not renew daily.

How do I write a useful video prompt?

Start with a subject and a single action. Add the setting, camera movement and lighting. In Koor AI, short, deliberate briefs make it easier to compare a result with your original idea and refine the next take.

Can I animate an existing image?

Choose Kling 4.0 Image to Video or Kling 3.0 Image to Video in the Koor AI studio and upload an image you have permission to use. Describe the movement you want, and optionally provide an ending frame. Kling 4.0 includes synchronized audio and offers clips up to 30 seconds.

How much do additional videos cost?

Kling 4.0 costs 5 credits per second at 720p and 8 at 1080p, with audio always included: a 5-second 720p clip is 25 credits and a 10-second 1080p clip is 80. Kling 4.0 Video Edit, and Reference to Video with reference videos, cost 3 credits per counted second at 720p or 4 at 1080p, where counted seconds are the output length plus the longer of the output length and your uploaded video time. Kling 3.0 costs 4 credits per second: 12 credits for 3 seconds, 20 for 5, 40 for 10 and 60 for 15; disabling its sound does not reduce the price. Review the available plans on the pricing page.

What happens if a generation fails?

Confirmed failed generations return reserved credits through your account balance. If a task is still being checked, keep its existing task rather than resubmitting the same request.

Is Koor AI affiliated with Kuaishou or Kling AI?

This is an independent workspace, not an official Kuaishou service. Kling and related model names belong to their respective owners. Each result uses the model selected in the generator.

Make your first video with Koor AI

Kling 4.0 is live in Koor AI: turn text or an image into 3–30 second videos at 720p or 1080p with synchronized audio. Kling 3.0 is available too.
