LTX 2.3 Fast turns text prompts and reference images into short videos at resolutions up to 4K, with synchronized audio generated automatically alongside the footage. If you've ever needed a quick video for a product page, a social post, or a client pitch but had no time or budget to shoot footage, this model fills that gap in under a minute. The model supports clips up to 20 seconds at 1080p, or shorter clips at 2K and 4K at up to 50 frames per second for crisp, smooth motion. Camera motion presets (dolly in, dolly out, jib up, jib down, static, and more) let you direct the shot without touching any camera. You can also provide both a first and last frame image, and the model interpolates the action between them, giving you control over exactly where the scene starts and ends. It fits naturally into content production workflows where speed matters. Batch out several prompt variations, pick the best take, and move on. Picasso IA runs the model without any installation, so you can start testing prompts right away and iterate until you land on the clip you need.
LTX 2.3 Fast is a text-to-video model that produces high-resolution clips with synchronized audio from a written prompt, a reference image, or both. It solves the problem of needing video footage on a tight timeline: a product demo due tomorrow, a social post that needs motion, a concept you want to show before you have time to shoot anything. On Picasso IA, you can go from a blank text box to a 4K clip in under a minute. The model is tuned for speed without sacrificing the resolution and frame rate that make a video worth sharing.
Do I need programming skills or technical knowledge to use this? No, just open LTX 2.3 Fast on Picasso IA, adjust the settings you want, and hit generate.
Is it free to try? Yes, you can run LTX 2.3 Fast on Picasso IA without installing anything or entering a credit card to get started. Check the current plan page for details on generation limits.
How long does it take to get results? Short clips at 1080p typically finish in well under a minute. Longer clips at 4K take a bit more processing time, but the model is built for speed at every resolution setting.
What output formats are supported? The model outputs a video file you can download directly from the page. Audio is included by default and can be turned off if you prefer a silent clip.
Can I customize the output quality or style? Yes. You control resolution (1080p, 2K, or 4K), frame rate (24, 25, 48, or 50 FPS), duration (6 to 20 seconds), aspect ratio (16:9 or 9:16), and camera motion. The prompt itself gives you the most direct control over the visual style and mood.
What happens if I'm not happy with the result? Tweak the prompt, change the camera motion preset, adjust the duration, or try a different frame rate, then run it again. Generation is fast enough that working through several versions takes only a few minutes.
