LongCat Video

LongCat Video Text to Video 480p turns a complete written shot specification into a low-resolution video proxy. It is the economical full-model text route for exploring subject staging, action timing, camera movement, and aspect ratio before a production team invests in larger frames. With no source image to carry visual assumptions, the prompt should name concrete visible events and keep the sequence simple enough to judge clearly at 480p.

The endpoint exposes fps, total frames, aspect ratio, guidance, inference steps, quality level, write mode, and four output containers. Its 480p ceiling makes it well suited to previsualization, prompt A/B tests, and large candidate pools, while the absence of refinement-step control keeps the workflow lean. Compare story and motion rather than microscopic detail, then transfer an approved brief to the 720p route for closer review.

Highlights

• 480p proxy-first text generation. This route renders written scene direction at a fixed 480p target, making broad prompt and motion exploration economical before an HD pass.
• Lean generation controls. num_inference_steps, guidance_scale, num_frames, and fps expose the main trade-offs for fast preview creation without a separate refinement stage.
• Composition across delivery shapes. Ten aspect_ratio choices cover cinematic, square, landscape, and portrait proxies while preserving the route's 480p review purpose.
• Review-friendly encodes. X264, VP9, ProRes 4444, and GIF outputs plus fast, balanced, or small write modes let teams tailor proxies to browser review, editing, or lightweight sharing.

When to Use

Prompt Guide

Start with the desired result, then describe the source relationship, subject action, composition or camera behavior, lighting, style, and timing. For text-to-video generation, state what must remain stable as clearly as what should change. Use only fields exposed by the schema; the example below is structurally valid for this route.

{
  "prompt": "realistic filming style, a person wearing a dark helmet, a deep-colored jacket, blue jeans, and bright yellow shoes rides a skateboard along a winding mountain road. The skateboarder starts in a standing position, then gradually lowers into a crouch, extending one hand to touch the road surface while maintaining a low center of gravity to navigate a sharp curve. After completing the turn, the skateboarder rises back to a standing position and continues gliding forward. The background features lush green hills flanking both sides of the road, with distant snow-capped mountain peaks rising against a clear, bright blue sky. The camera follows closely from behind, smoothly tracking the skateboarder’s movements and capturing the dynamic scenery along the route. The scene is shot in natural daylight, highlighting the vivid outdoor environment and the skateboarder’s fluid actions.",
