LTX-2.5-Pro

LTX-2.5 Pro is the higher-fidelity variant of LTX-2.5, Lightricks' latest video generation model. It turns a text prompt or a starting image into video up to 4K, in landscape, portrait or square, at cinematic frame rates, with an AI-generated audio track that matches the scene.

LTX-2.5 improves every stage of generation: a diffusion video decoder for higher pixel quality, finer detail in texture, faces and typography, stronger prompt adherence, and native multi-shot scenes. A single generation can produce several connected shots that keep character, scene, lighting, visual style and voice consistent across cuts.

• Text-to-video and image-to-video in 16:9, 9:16, 1:1, 3:2 and 2:3
• Up to 4K, at 24, 25, 48 or 50 fps
• Clips of 6, 8 or 10 seconds
• Synchronized audio, or silent video with generate_audio: false
• Camera motion presets: dolly in/out/left/right, jib up/down, static, focus shift
• First and last frame control for image-to-video

Image-to-video

Pass image_url to animate an image from its first frame, and optionally last_frame_url to set where the clip ends. Each takes an https URL (up to 15 MB), a base64 data URI or a file upload (up to 7 MB encoded), in PNG, JPEG or WebP. Image-to-video costs the same as text-to-video.
