AI 4K Video Generator — Native 3840×2160 at 60fps
True 4K video, generated — not upscaled
Generate native 4K AI video at 3840×2160 up to 60fps, powered by Kling V3. No upscaling, no interpolation — real pixels straight from the diffusion model, ready for broadcast, large-screen, and hero shots.
Why Our AI 4K Video Generator
Native 4K Resolution
Generate true 3840×2160 AI video straight from the diffusion model — no upscaling, no interpolation. Every pixel is real output.
Up to 60fps Smooth
Native 60fps output for buttery motion — ideal for sports, action, and YouTube content where the platform rewards high frame rates.
Powered by Kling V3
Backed by Kling Video 3.0, currently ranked #1 on the AI video ELO leaderboard. Cinematic lighting, subsurface detail, sub-pixel texture.
Broadcast-Ready Output
16-bit HDR color depth and ProRes export — hand off directly to a broadcast QC pipeline without a separate grading pass.
When 4K Actually Matters
Broadcast TV & TVCs
4K is the delivery standard for TV commercials and broadcast QC. Ship ProRes 4K straight from our generator to your post-production timeline.
Large-Screen Installation
Event LED walls, conference hero videos, showroom installs. Above ~55 inches, 1080p pixels start showing — 4K earns its keep here.
YouTube Long-Form & Cinematic
YouTube rewards 4K content with a visible quality badge and algorithmic lift for documentary and cinematic work. 60fps helps retention.
Product & E-Commerce Close-Ups
Jewelry, watches, leather goods, woven fabric — categories where the close-up is the whole reason the camera is there. 4K texture sells.
How It Works
From prompt to 4K export in four steps
Pick Input Mode
Start from a text prompt or upload a reference image. Image-to-video is the most common path for 4K product and hero shots.
Enable 4K Mode
Toggle the Professional 4K switch in the generation panel, pick aspect ratio (16:9 / 9:16 / 1:1), and set duration up to 15 seconds.
Draft at 1080p First
Run a cheap 720p preview to lock in motion and composition — then burn 4K credits only on the take that actually works.
Export in 4K
Generate the final render at 4K Pro or 4K Master, download in ProRes / H.265 / H.264, and ship it straight to your edit timeline.
AI 4K Video Generator FAQ
What is an AI 4K video generator?
An AI 4K video generator produces video clips at 3840×2160 resolution — four times the pixel count of 1080p — using an AI model. ImagineToVideo's 4K mode runs Kling V3, which generates the 4K frames natively from the diffusion process rather than upscaling a lower-resolution output.
Is this native 4K, or is it upscaled from 1080p?
Native 4K. The model renders at 3840×2160 end-to-end — no ESRGAN upscaling, no Topaz pass, no 'detail hallucination' layer. You get real sub-pixel detail: fabric weave, skin micro-texture, tool marks on metal — information an upscaler cannot invent from lower-resolution input.
What frame rates and aspect ratios are supported?
Up to 60fps in Professional mode, with 16:9, 9:16, 1:1, and 21:9 cinematic ratios supported natively. Some mode combinations cap at 30fps — if you're delivering to broadcast, double-check fps in the export file before signing off.
How long can a single 4K video clip be?
Up to 15 seconds per clip with Kling V3 in 4K mode — a meaningful jump from the 10-second ceiling of Kling 2.6. For longer sequences, chain multiple clips in a timeline or use Kling V3 Omni's multi-shot mode for up to 6 connected shots.
How much do 4K generations cost versus 1080p?
4K renders consume roughly 2–3× the credits of a 1080p render at the same duration. We recommend drafting in Standard at 1080p to nail motion and composition, then burning 4K credits only on the final take — this single workflow habit saves more credits than any prompt technique.
When should I actually use 4K instead of 1080p?
4K pays off for broadcast TV delivery, large-screen installations (≥55″), long-form YouTube, and product shots where close-up texture carries the pitch (jewelry, fabric, leather). For a 9:16 TikTok clip viewed on a phone at 40% brightness, 1080p is the right call — don't burn 4K credits out of habit.
