Quick take
LTX-2.5 Pro
Lightricks' quality-focused video model for making 720p or 1080p clips from text, images, or audio with native sound.
Best for
- Short 1080p creative video
- Audio-led or image-led animation
- Shot-based production with predictable unit cost
Watch out for
Native audio is on by default and adds creative variables that need review. Test dialogue, voice consistency, shot boundaries, and the exact frame-rate option before scaling a production workflow.
LTX-2.5 Fast
LTX's speed-optimized video model for text, image, or audio input, native sound, automatic duration, and output up to 4K.
Best for
- Fast video experiments with native audio
- Portrait or landscape output up to 4K
- Prompt-driven multi-shot clips with automatic duration
Watch out for
Fast does not mean every 4K job finishes instantly. Price grows from $0.09 to $0.30 per generated second, and permitted duration depends on resolution and frame rate.
