Overview

WAN T2V is a text-to-video model from Pruna. It takes a detailed scene description and synthesizes a short video clip as a sequence of generated frames. It then packages the result as a playable MP4, which makes it easy to drop into edits or prototypes. The main value is fast iteration on motion, camera ideas, and style without filming.

What you can build

  • 5-second concept clips for storyboards and pitch decks
  • Vertical social posts (9:16) from a single written shot description
  • Landscape b-roll ideas (16:9) for ads, trailers, and mood reels
  • Style explorations like cinematic, anime, macro, or watercolor looks
  • Quick motion tests for “camera moves” like pan, dolly, and drone shots

Inputs

  • A required written description of the scene, including action, motion cues, camera movement, and visual style.
  • A required output resolution choice of 480p or 720p.
  • An optional aspect ratio choice of 16:9 (landscape) or 9:16 (vertical). For 16:9, outputs map to 832×480 or 1280×720. For 9:16, outputs map to 480×832 or 720×1280.
  • An optional toggle to enable frame interpolation for smoother motion. When enabled, the output video is upsampled to 30 fps.
  • An optional toggle for a fast mode. Turn it off when you want higher visual quality.
  • An optional toggle to auto-optimize the prompt by translating it to Chinese before generation.
  • An optional motion shift control (a decimal number from 1.0 to 20.0). Higher values tend to increase visible motion.
  • An optional seed value (an integer from 0 to 99,999,999) to help reproduce a result. Set it to 0 to randomize.
  • An optional toggle to skip the safety checker on generated content.

Outputs

  • A single MP4 video clip.
  • The clip matches the selected resolution and aspect ratio.
  • If frame interpolation is enabled, the MP4 is delivered at 30 fps for smoother playback.

Limitations

  • The model generates short clips (about 5 seconds). It isn’t meant for long scenes.
  • Output size is limited to 480p or 720p, with only 16:9 or 9:16 framing.
  • Text-only conditioning can miss exact details like logos, specific text, or consistent identity across frames.
  • Fast mode can reduce fine detail, increase artifacts, or soften textures.
  • Results depend heavily on prompt quality. Vague prompts often produce unclear motion or unintended scene changes.
  • Seeds can improve repeatability, but changes to resolution, aspect ratio, or motion settings can still change outcomes.

Safety & compliance

  • The model can run with a safety checker. If you disable it, you take responsibility for the output.
  • Don’t generate sexual content, nudity, or graphic violence.
  • Don’t generate content involving minors in sexual contexts.
  • Respect privacy and likeness rights. Get permission before depicting real people.

Example prompts

Great starting points for wan-t2v.

Extreme close-up macro shot of a single water droplet sliding down the vein of a vibrant green leaf. The droplet falls off the tip of the leaf in slow motion, creating a tiny splash. Highly detailed, photorealistic, blurred background (bokeh), natural sunlight shining through the leaf.Video Generation
Close-up portrait of an 80-year-old wise man with deep wrinkles and a grey beard, sitting in a dimly lit rustic cabin. The warm orange light of a roaring fireplace illuminates his face. He blinks naturally, smiles warmly, and looks directly into the lens. Ultra-detailed, cinematic film grain, dramatic chiaroscuro lighting.Video Generation
A majestic Siberian tiger running at full speed through a dense, snow-covered pine forest. Shot in ultra slow motion. With every heavy footstep, chunks of bright white snow are kicked up into the air. Sunbeams filter through the trees. High-end nature documentary style.Video Generation
Professional food commercial shot. A fresh coffee bean falls in slow motion into a steaming cup of dark coffee against a pure black background. Upon impact, artistic splashes of coffee fly into the air. Sharp focus, dramatic studio lighting, extreme detail.Video Generation
