Image-to-video

Generate high-quality video with audio from images using LTX-2.3

LTX 2.3 Quality Image-to-Video

LTX 2.3 Quality Image-to-Video animates a static image into a high-quality video guided by a text prompt. It produces fluid, temporally consistent motion while preserving the visual style, colors, and composition of the source image.

🌟 Key Features

🖼 Image-Driven Animation

Breathe life into any static image — photos, illustrations, or AI-generated artwork — with prompt-guided motion and cinematic quality.

🔊 Optional Audio Generation

Optionally generate synchronized audio alongside the video in a single request.

📐 Multiple Resolution Presets

Six aspect ratio presets to match any layout requirement.

🔁 Reproducible Results

Pin a seed value to reproduce or iterate on a specific generation.

⚙️ Parameters

💡 Prompt Tips

The flowers sway gently in the breeze, petals catching the sunlight, soft bokeh background slowly shifting.

  • Focus the prompt on motion: "camera slowly zooms in", "gentle wind moves the trees", "waves lap at the shore".
  • Keep the prompt consistent with the image content — contradictory prompts produce unstable motion.
  • Use short, specific motion descriptions for best results; long narrative prompts can reduce temporal coherence.
  • Fix seed when tweaking prompt wording to isolate motion changes.

🎯 Use Cases

  • Product Animation — Animate product photos for e-commerce with subtle, professional motion.
  • Portrait & Character Animation — Add lifelike motion to portraits, illustrations, or avatars.
  • Landscape & Nature — Bring scenic photos to life with realistic environmental motion.
  • Art & Illustration — Animate concept art, paintings, and graphic design assets.
  • Social Media Content — Transform static posts into engaging short video clips.

📝 Notes

  • Both prompt and image_url are required.
  • num_frames must satisfy: (num_frames - 1) % 8 == 0 (e.g. 25, 33, 41, 81, 121, 161, 257).
  • Task status values: created, processing, completed, failed.
  • Generated video URLs are returned in outputs once status is completed.
