Positioning Overview

kling-3.0/text-to-video is the text-to-video route in the Kling 3.0 series: enter a text description and generate a finished video with optional native audio. It supports durations from 3 to 15 seconds, resolutions from 720p to 4K, and landscape, portrait, and square aspect ratios. It is suited to developers and content teams that need to turn scripts or ideas into publishable videos quickly, and per-second billing makes it easy to control costs by clip length.

Key Highlights

  • Text-to-video with native audio — when the audio option is enabled, it generates sound effects and ambient sound synchronized with the visuals, eliminating the need for a separate dubbing step.
  • Resolution and aspect ratio coverage for mainstream publishing needs — 720p, 1080p, and 4K resolutions and 16:9, 9:16, and 1:1 aspect ratios let a single call match landscape, portrait, and square placements.
  • Adjustable duration to fit the narrative — generate 3 to 15 seconds per call, so short films and multi-shot segments can both be completed within the same interface.

Capability Description

Pure text to finished video: submit only a prompt to produce a video, ideal for teams that already have scripts or copy but lack footage and need to produce videos quickly.

Choose native audio or silence: optionally enable synchronized sound effects and ambient sound, or turn audio off and output visuals only, making it easy to add your own music or voiceover in post-production.

Parametric resolution and aspect ratio: control output specifications directly through resolution and aspect ratio parameters, reducing the quality loss caused by cropping and scaling after generation.

Duration linked to cost: billing is by output seconds, so shortening duration or lowering resolution compresses the cost per clip, making batch test clips easier.

Use Cases

  • Marketing teams quickly produce ad clips from copy — turn campaign copy into 9:16 or 16:9 finished videos for direct use in feed ads and brand short videos.
  • Content creators mass-produce vertical short videos — batch-generate 9:16 short-video assets by topic for daily updates on social platforms.
  • Validate storyboard ideas when live-action footage is lacking — generate short clip previews from text descriptions to evaluate shot effects for early-stage storyboarding and creative review.

Limitations and Selection Advice

The maximum duration per generation is 15 seconds; long narratives need to be generated in segments and then stitched together. Native audio covers only sound effects and ambient sound, not dialogue or lip sync; dialogue content requires separate audio or a different route in the series. Resolution, duration, and the audio switch all affect cost, so before mass production it is advisable to validate results with a low-resolution short clip first. If reference images are available or motion control is needed, choose the image-to-video or motion-control route in the same series.
