LTX 2 Fast Image-to-Video (Fast I2V) is the accelerated engine designed specifically for fast image-to-video animation. It takes an input image and a prompt to generate motion clips in seconds. This mode is essential for creators who rely on fast image-to-video animation to iterate on movement, effects, and scene transitions without the longer wait times of Pro mode.
image_url sets the visual foundation (subject, color, composition).prompt, optimized for fast image-to-video animation.Use Fast I2V as your creative sandbox:
1) Upload an image and generate multiple fast image-to-video animation variations.
2) Choose the clip with the best movement.
3) Send it to Retake to slow it down, change timing, or fix artifacts: LTX 2 Retake Video

Speed. This tool is built for fast image-to-video animation, enabling you to iterate on motion concepts, test camera moves, and generate previews in a fraction of the time required for high-fidelity rendering.
Fast mode generally preserves the core subject and composition, but it prioritizes fast image-to-video animation speed over pixel-perfect identity retention. For critical identity preservation (e.g., specific faces), Pro Image-to-Video is recommended.
It is significantly faster, especially at 1080p resolution. This reduced latency makes fast image-to-video animation feasible for running multiple experimental generations to find the perfect motion before scaling up.
Yes. Fast image-to-video animation is great for content where motion and vibe are more important than 4K texture detail. Many users find the 1080p/50fps output perfect for Instagram Reels, TikToks, and other mobile-first platforms.
If you like a motion generated in Fast mode but want to tweak it, you can send your fast image-to-video animation output directly to LTX 2 Retake Video to refine it without starting from scratch.
Negligibly. The audio generation model is efficient and runs in parallel, complementing the fast image-to-video animation process. We recommend keeping generate_audio enabled (default) to get a complete audiovisual preview.
