Generate AI video in supported 4K modes

Seedance 2.0 Standard currently includes a native 4K resolution option for its supported text, image, first-and-last-frame, and reference workflows. Seedance Fast and Mini currently top out below 4K.

Kling 3.0 Standard and Kling 3.0 Omni expose a separate 4K quality option on supported workflows. Kling 3.0 motion control is limited to Standard and Pro quality, so 4K should not be assumed across every Kling mode.

A 4K output contains more pixels than lower-resolution options, but it cannot guarantee correct text, anatomy, logos, reflections, product geometry, or temporal consistency. Those properties still depend on the model, prompt, source assets, and generated result.

Review the full-resolution file rather than judging only a reduced preview. Fine artifacts, flicker, texture changes, or edge errors can become easier to see at a larger delivery size.

For image-led generation, begin with a clean authorized source whose composition fits the intended frame. For text-to-video, use a focused prompt and avoid overloading a short shot with unrelated subjects or competing camera directions.

Supported ratios, durations, references, and audio settings remain model-specific. Kling 4K quality currently disables its optional audio control, while other 4K-capable configurations apply their own audio behavior.

• Select 4K only where the active model offers it
• Inspect important details at delivery resolution
• Check the current duration, audio, access, and credit quote

A supported 4K generation asks the video model to produce that output setting directly. Upscaling is a separate RedVideo workflow that enlarges a completed image or video and does not recreate the same generation request.

The right path depends on the source, model, delivery need, and current cost. Compare a native high-resolution run with an upscale of an approved lower-resolution result when consistency and budget both matter.
