Create rapid high-quality video drafts with precise style and speed
LTX 2 Pro Image-to-Video (I2V) turns a single reference image plus a prompt into a coherent video. It's built for maximum fidelity: preserve subject identity, add controlled camera/motion, and optionally generate synchronized audio. Use it to animate images with LTX 2 for cinematic results.
image_url.prompt describes motion, atmosphere, and camera moves (e.g., "slow dolly in", "pan right").Use I2V to create a strong first pass, then refine with targeted edits:
1) Generate your base clip here.
2) Send it to Retake to adjust motion intensity, re-time segments, or refine specific regions without starting over: LTX 2 Retake Video

Seedance 2.5 4K Image to Video: animate stills into 4K motion
Create 1080p cinematic clips from stills with physics-true motion and consistent subjects.
Produces crisp 1080p AI videos with smart motion logic and speed
Prompt-driven Pro-tier video editing at $0.167 per second.
Generate cinematic videos from text prompts with Seedance 1.0.
It animates a single reference image into a coherent video clip guided by your prompt. Use it to animate images with LTX 2 when you need cinematic motion, strong subject preservation, and optional synchronized audio.
This Pro I2V workflow is image-conditioned. The image_url anchors composition and identity, while the prompt specifies motion and camera. This mechanism yields higher fidelity and stability than text-only inputs.
Pro prioritizes fidelity over raw speed. Latency increases with resolution (1080p < 1440p < 2160p) and FPS (25 < 50). Expect longer runtimes than fast text-to-video generation baselines, especially at 4K and 50 FPS.
Resolution up to 2160p (4K), durations of 6/8/10 seconds, aspect ratio fixed at 16:9, and FPS at 25 or 50 to balance motion smoothness and coherence.
First generate a solid base clip here, then refine specific regions, motion intensity, or timing in Retake: LTX 2 Retake Video. This avoids starting over and speeds up creative iteration.
Yes. Set generate_audio=true (default) to receive a video with synchronized ambience and sound effects that match on-screen events.
