How to generate with Kling v4
Open the AI Studio
Open AI Studio from the editor and choose Kling v4. What it generates lands in the project you are already working in.
Attach your image and pick Kling v4
Upload the still you want moving. The picker switches to image-to-video models as soon as an image is attached. Set the length within what it accepts (3s to 15s) and add a prompt describing the motion.
Balance it against your voice
Kling v4 generates its own audio, so the clip arrives with sound. Drop it on the timeline, cut it to the beat you want, and lower its track under your recording so the two are not competing.
What Kling v4 is for
Kling v4 is an image-to-video model from Kuaishou, available in REQO's AI Studio. It animates a still you upload rather than inventing a shot from a prompt alone. Clips run 3s to 15s, with a soundtrack generated alongside the picture, and it sits in the highest quality tier at 10 credits for its shortest clip.
Against the 15 other image-to-video models in the studio it is the 10th-cheapest to run and comes back 3rd quickest, at 10 credits and about 60 seconds a generation.
In the picker it is described as: Newest Kling, up to 15s.

What a Kling v4 clip costs
A Kling v4 clip runs from 10 credits (3s at 720p) to 71 (15s at 1080p). Resolution is part of the price, so pick it with the length. These are the figures the studio charges, shown again before each generation.

| Resolution | 3s clip | 8s clip | 15s clip |
|---|---|---|---|
| 720p | 10 credits | 26 credits | 48 credits |
| 1080p | 15 credits | 38 credits | 71 credits |
When to pick Kling v4
You already have the frame - a product shot, a still from a shoot, an image you generated a moment ago - and want up to 15s of movement out of it, at 720p or 1080p.
The clip you need fits inside 3s to 15s, and you can wait about 60s for it.
You would rather not think about framing at all: the clip comes back in the shape of the image you gave it.
You want sound generated with the picture instead of added on the timeline.
Where it runs out: Kuaishou built this endpoint to animate a still rather than to generate one, so there is no prompt-only path into it. Clips stop at 15s; Seedance 2.5 goes to 30s if you need one shot to run longer. Resolutions are limited to 720p or 1080p, and the higher ones cost more credits. At 10 credits it is not the cheap option: Kling v3 Standard runs at 9. Nor the quickest: PixVerse V6 answers in about 45s against this one's 60s.
What to weigh Kling v4 against
These are the 5 models closest to Kling v4 on price, render time and clip length - the ones worth weighing it against. Every model REQO offers is linked below.
They all run on the same timeline, so the choice is per clip rather than per project: generate an establishing shot with one and a quick filler with another, then cut them together in the same tab. Credit costs are each model’s cheapest clip, its shortest length at its cheapest resolution; longer clips cost more.

Generating is the easy half
Most generators hand you a clip and stop, which leaves you downloading files and re-uploading them somewhere else to make anything of them.
In REQO the Kling v4 result lands next to your screen recordings and uploads, about 60 seconds after you attach the still. It renders 16:9 only, so frame for that before you generate.
The AI Studio (talking avatars, text-to-video and AI images) and the AI clip tools (background removal, chroma key, face touch-up, noise cancellation, auto cleanup, auto b-roll, auto-zoom) are Pro features. Generation includes 100 credits a month plus top-ups.
Kling v4: questions
How much does Kling v4 cost?
From 10 credits (3s at 720p) to 71 (15s at 1080p), and the studio shows the exact figure for the length and resolution you pick before it charges you. AI Studio is part of Pro.
How long can a Kling v4 clip be?
3s to 15s. That is a hard limit of the model, not a plan limit - a longer piece is several generations laid end to end.
What shape is the video Kling v4 produces?
It follows the image you upload, so the framing is decided before you generate. To change it afterwards, the free crop tool handles every social ratio.
Can Kling v4 generate a video without an image?
No. This endpoint animates a still, so an image is required. Remove the image and the studio switches you to the text-to-video side of the same family automatically.
Does Kling v4 generate audio?
Yes, it produces a soundtrack alongside the picture, inside the 10 credits the clip already costs. You can still add music or a voiceover on the timeline.
How long does a generation take?
Usually about 60 seconds for the 10-credit shortest clip; longer clips and higher resolutions take proportionally longer. Generations keep running if you switch tabs.
Can I edit the generated clip?
Yes, and on the same timeline as everything else. The still you animated stays in the project, so you can re-run it with a different prompt and cut the two takes together. Captions come off the transcript, and the finished piece exports or shares as one link.
