LTX 2 Pro API for Image to Video

LTX‑2 Pro Image‑to‑Video takes a single still image and turns it into a 6–10 second, 16:9 video clip with cinematic motion and synchronized audio, while largely preserving the original look.​

What LTX‑2 Pro Image‑to‑Video does

• Starts from one input frame (photo, render, or AI image) and animates it into a smooth video with camera motion, subject motion, or both.​

• Outputs 1080p, 1440p, or 4K (2160p) at up to 50 fps, so even simple images become broadcast‑grade motion shots.​

• Generates an audio track in the same pass (ambience, light SFX, simple music) that matches the visual pacing, removing the need for manual sound syncing.​

Typical workflow from one image

1. Upload image

   • Provide a high‑quality JPG/PNG/WebP; results improve if the image already matches a 16:9 ratio and has clean detail.​

2. Write a motion prompt

   • Describe:

     • Camera moves (for example, slow push‑in, orbit, pan across scene).

     • Subject motion (subtle breathing, hair movement, environmental motion like clouds or water).

     • Mood and style (cinematic, vlog, product ad, dreamy, etc.).​

3. Choose settings

   • Duration: 6, 8, or 10 seconds.

   • Resolution: 1080p, 1440p, or 4K; fps usually 25 or 50.​

   • Audio: enable “Generate Audio” to get synchronized sound designed to fit the scene.​

4. Generate and iterate

   • Render a first pass, then refine the motion prompt (slower/faster camera, more or less subject movement) until it matches your storyboard.​

Where it’s especially useful

• Turning product or key art images into quick cinematic promos with gentle camera moves and light motion.​

• Breathing life into character stills for intros, outros, and social clips without running a full text‑to‑video pipeline.​

• Slotting into ComfyUI and similar node‑based pipelines via LTX‑Video partner/API nodes for image‑to‑video plus built‑in audio.
