Product Overview
ltx-2.3 is an AI video generation application built around the officially Replicate-hosted LTX 2.3 Fast and LTX 2.3 Pro models, used to create cinematic videos. Users can start from text or a single image to generate highly dynamic AI videos.
Key Capabilities
- Text-to-Video: Generate videos from text prompts, such as a futuristic corridor light sweep with clean geometric motion and sharp contrast.
- Image-to-Video: Supports start frame and end frame control, allowing the first frame to be animated into a dark tech-style push-in while maintaining precise motion continuity.
- Image Stability and Motion Control: You can add advanced lighting motion and slow parallax while keeping the scene composition stable; or turn a single static visual into an advertising-style dynamic clip with subtle camera movement.
- Output Specifications: You can choose 1080p to 4K output, and set generation parameters such as duration, FPS, and aspect ratio.
How to Use
Switch between LTX 2.3 Fast and LTX 2.3 Pro within the same workspace, scale from quick tests to advanced rendering, and use supported long-format LTX 2.3 shots. The application currently focuses on two workflows, text-to-video and image-to-video, including optional start frame and end frame control when supported by the selected model configuration.
Billing and Credits
A credit-based system is used, and credit consumption varies with generation settings: higher resolution, longer duration, advanced model variants, and high FPS settings consume more credits.
Subscription plans (billed annually):
- $99/year: 4455 credits/year, up to 247 videos/year at the lowest-cost settings, includes LTX 2.3 Fast access, text-to-video and image-to-video, annual savings compared with monthly billing, private generation. Suitable for individual creators using LTX 2.3 Fast to validate prompts and concepts.
- $299/year: 13455 credits/year, up to 747 videos/year at the lowest-cost settings, includes Fast and Pro access, more 2K and 4K output headroom, suitable for creator businesses and internal teams.
- $499/year: 22455 credits/year, up to 1247 videos/year at the lowest-cost settings, includes high-volume Fast iteration, advanced Pro rendering budget, stable annual production capacity, priority support. Suitable for teams with frequent previews, client concepts, and advanced exports.
One-timeCredit packs (top up generation counts without changing your subscription):
- Small top-up pack: up to 16 videos at the lowest-cost settings, fast Fast generation.
- Balanced top-up pack: up to 50 videos at the lowest-cost settings, batch prompt exploration, mixed use of Fast and Pro.
- Larger reserve pack: up to 86 videos at the lowest-cost settings, for launch campaigns and higher-resolution Pro renders.
"Up to X videos" on the pricing page is based on the cheapest effective supported generation settings: LTX 2.3 Fast, 1080p, 6 seconds. If more expensive settings are chosen, the number of videos each plan can generate will decrease.
Use cases
- Teams iterating faster on motion rounds
- Workflows for testing prompts, frames, and output tiers
- Transitioning from fast Fast previews to more advanced Pro renders
- Frequent previews, client concepts, and advanced exports for creator businesses and internal teams
Limitations and notes
- Credit consumption increases as settings are raised; choosing higher resolution, longer duration, higher FPS, or Pro variants will reduce the number of videos each plan can generate.
- Paid plans are intended for commercial-use workflows on this site, but for policy-level certainty for a specific business use, you should still review the upstream model and platform terms.
- More details on the model's specific technical parameters, maximum supported duration, and similar information are not currently provided in the materials.
