How it works

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.
Pick Kling v4 and describe the shot
Choose the model, set length and aspect ratio within what it accepts (5s to 15s, 16:9, 9:16, 1:1), then write the prompt.
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 a text-to-video model from Kuaishou, available in REQO's AI Studio. Clips run 5s to 15s, with a soundtrack generated alongside the picture, and it sits in the highest quality tier at 16 credits for its shortest clip.

Against the 19 other text-to-video models in the studio it is the 16th-cheapest to run and comes back 3rd quickest, at 16 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 16 credits (5s 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.

When to pick Kling v4

The clip you need fits inside 5s to 15s, and you can wait about 60s for it.

You need 16:9, 9:16 or 1:1 - no other text-to-video model here accepts as many natively.

You want sound generated with the picture instead of added on the timeline.

Where it runs out: Clips stop at 15s; FLUX 3 goes to 20s if you need one shot to run longer. Resolutions are limited to 720p or 1080p, and the higher ones cost more credits. At 16 credits it is not the cheap option: Kling 2.6 Pro runs at 14. Nor the quickest: Hailuo 2.3 answers in about 35s 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 describe the shot. Pick the aspect ratio before you generate (16:9, 9:16, 1:1); afterwards it is a crop.

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.

FAQ

Kling v4: questions

How much does Kling v4 cost?

From 16 credits (5s 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?

5s 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 aspect ratios does Kling v4 support?

16:9, 9:16, 1:1, at 720p, 1080p. Anything else is a crop afterwards, which the free crop tool handles.

Does Kling v4 generate audio?

Yes, it produces a soundtrack alongside the picture, inside the 16 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 16-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. A 5s to 15s clip is usually one shot, so generate the two or three you need and cut them in sequence. Captions come off the transcript, and the finished piece exports or shares as one link.
