Two ways to a 4K AI video
Native 4K models
Kling v3 4K renders 3–15 second clips in 4K, with sound you can switch on. Veo 3.1, Seedance 2.5 and LTX 2.5 also have a 4K setting.
Free AI video upscaler to 4K
Upload a clip of 5 to 60 seconds and upscale it to 1080p, 2K or 4K with detail recovery — AI clips or your own footage.
Text or image to 4K
Start from a prompt, or from an image as the first frame; many models also take an end frame.
Native sound
Kling v3 4K and Veo 3.1 can generate sound with the picture, so a 4K clip arrives with its own audio.
No watermark
4K downloads carry no watermark or Kenerate branding.
4K stills too
Need a 4K thumbnail or poster frame? The image upscaler takes any image up to 8K or 128 MP.

FAQ
Frequently Asked Questions
Is the 4K AI video generator free?
Free to start, not free forever. A new Kenerate AI account gets free credits you can spend on the video upscaler and on images. Making video with the 4K models — Kling v3 4K, Veo 3.1, Seedance 2.5 and LTX 2.5 — needs a one-time credit pack. There is no subscription required, credits never expire, and downloads have no watermark.
Link to this answerWhich AI video models make native 4K?
Kling v3 4K, Veo 3.1, Seedance 2.5 and LTX 2.5 all have a 4K setting in the Kenerate Video Studio. Kling v3 4K makes 3–15 second clips with optional sound, and Veo 3.1 makes clips of up to 8 seconds, also with sound. Pick the model, set 4K, then describe the shot or add a start image.
Link to this answerHow do I upscale a video to 4K for free?
Open the Video Upscaler, upload a clip between 5 and 60 seconds long, choose 1080p, 2K or 4K and start. It recovers detail as it enlarges and works on AI clips and your own footage. New Kenerate AI accounts can spend their free credits on it; longer clips and 4K use more credits. Results download without a watermark.
Link to this answerIs native 4K better than upscaling to 4K?
For a new shot, usually yes: a native 4K model draws fine detail at full size from the start. Upscaling is the better choice for a clip you already have, such as a 1080p AI video or your own footage, because it keeps the motion and framing exactly as they are. Both routes give a 4K file without a watermark.
Link to this answerCan I use 4K AI videos commercially?
Yes. You own what you make on Kenerate AI and can use it commercially — on YouTube, in ads, on social platforms or in client work. Downloads carry no watermark or Kenerate branding. Follow our content rules: no real people without their consent and nothing involving minors.

4K AI Video Generator Free, explained
How to make a 4K AI video
Pick a native 4K model. In the Video Studio, choose Kling v3 4K, Veo 3.1, Seedance 2.5 or LTX 2.5, set the resolution to 4K and describe the shot — subject, action, setting and camera move. LTX 2.5 is the 4K member of the LTX 2 family.
Or upscale what you have. The AI video upscaler takes any clip of 5 to 60 seconds — a 1080p AI video or your own footage — to 2K or 4K and recovers detail as it enlarges, keeping the motion and framing exactly as they are.
Know the cost first. A new Kenerate AI account gets free credits you can spend on the upscaler and on images; generating video needs a one-time credit pack. Packs never expire, there is no subscription required, and every download is free of watermarks.
