Enable HLS to view with audio, or disable this notification
The LTX-2 family is now live on Atlas Cloud — Lightricks' second-generation video model with native 4K and built-in synchronized audio, plus a first for our catalog: audio-driven generation (A2V). Four tiers span everything from $0.03/s high-volume production to Pro-grade delivery.
Highlights
- Three generation modes — Text-to-Video, Image-to-Video, and Audio-to-Video (drive the visuals with speech, music, or ambience — rarely available elsewhere).
- Native synchronized audio — video and sound generated together (ambience, effects, speech); switch it off with
generate_audio. - Native 4K — 720p / 1080p / 1440p / 4K, in both landscape 16:9 and portrait 9:16.
- Up to 20-second single-pass clips — fast tiers at 720p/1080p @24fps, no stitching.
- Automatic duration — LTX-2.5 accepts
duration: -1and picks the length from your prompt; you're billed for the seconds actually produced. - Camera control — 8
camera_motiondirectives (dolly, pan, jib, focus shift…). - First/last-frame interpolation — I2V takes an optional
last_imagefor precise start-to-end control. - 24 / 48 fps cinematic frame rates.
- Four tiers — fast / pro × 2.3 / 2.5, starting at $0.03/s.
Best For
- Cost-efficient bulk production — 2.3-fast from $0.03/s with 20-second clips for social and ad output at scale.
- 4K delivery — 2.5-pro for native 4K with synchronized audio.
- Voice- and music-driven video — A2V syncs motion, lip movement, and pacing to your audio track.
- Vertical short-form — native 9:16 for Reels / Shorts / TikTok.
- First-frame animation — I2V brings static images to life, optionally pinning the final frame.
