Frequently Asked Questions
The model uses advanced AI algorithms to analyze your image and text prompt, then generates a sequence of video frames with realistic motion and transitions. It can also synthesize matching audio to enhance the video output.
You can create a wide range of videos, from cinematic clips and animated stories to marketing content, educational visuals, and engaging social media posts. The customizable settings allow you to tailor the output to your specific creative needs.
Yes, you have full control over key parameters such as frame count, frame rate, video size, output format, guidance scale, and video quality. The model also supports negative prompts to exclude unwanted elements and features multi-scale generation for added detail.
There is no fixed limit on the number of videos you can generate. The platform operates on a pay-as-you-go credit system, allowing you to scale your usage according to your project's needs.
Yes, LTX-2 19B includes an integrated safety checker to help prevent the generation of inappropriate or unsafe content, ensuring outputs are suitable for various professional and creative applications.
Credit usage scales with frame count, resolution, and advanced settings. A standard 121-frame video at 1080p with audio typically costs 15–25 credits, while a 481-frame 4K output with multi-scale enabled can reach 60–80 credits. Disabling audio generation or reducing inference steps lowers cost. For budget-conscious workflows,
LTX 2.3 Image to Video Fast offers similar quality at roughly 40% lower credit consumption. Check the live credit estimator in your JAI Portal dashboard before generation, and consider batching multiple images in a single session to amortize setup overhead.
Yes, all videos generated with paid credits on JAI Portal carry full commercial-use rights. You own the output and can incorporate it into client work, advertising campaigns, product demos, or resale without attribution. This applies to both the video frames and the synthesized audio track. Free-tier or trial generations may have watermarking or restricted licensing, so confirm your account status before finalizing deliverables. If you need batch processing or API access for enterprise workflows, JAI Portal supports programmatic generation with the same commercial terms, making it straightforward to integrate LTX-2 19B into automated content pipelines.
LTX-2 19B auto-detects your input image dimensions and generates video at the same aspect ratio by default. You can override this with presets like 'landscape_16_9' (1920×1080), 'portrait_16_9' (1080×1920), 'square_hd' (1080×1080), or 'custom' for manual width/height. Maximum supported resolution is approximately 1920×1920 pixels; larger inputs are downsampled. For ultra-wide or vertical formats,
Kling Video v3 Pro Image to Video handles non-standard ratios more reliably. Output formats include MP4 (H.264), WebM (VP9), MOV (ProRes 4444 for professional editing), and GIF, with quality presets from 'low' to 'maximum' to balance file size and visual fidelity.
Jittery motion often stems from ambiguous prompts, low-quality source images, or insufficient inference steps. First, ensure your input image is sharp and at least 1024px. Next, rewrite your prompt to specify smooth, continuous actions ('slow zoom in' instead of 'zoom'). Increase 'num_inference_steps' from 40 to 45–50 for more refined frame interpolation, though this adds generation time. Enable 'use_multiscale' for complex scenes with multiple moving elements. If issues persist, try lowering 'guidance_scale' to 2–2.5 to reduce over-correction. For physics-based motion that minimizes artifacts, compare with
NVIDIA Cosmos Predict 2.5 Image to Video, which uses world models for smoother trajectories.
Yes, JAI Portal provides a REST API for programmatic access to LTX-2 19B and all other models. You can submit multiple image-to-video jobs asynchronously, poll for completion, and retrieve results via webhook or direct download. This is ideal for agencies processing client galleries, e-commerce platforms animating product photos at scale, or content studios generating hundreds of social clips. API usage consumes the same pay-as-you-go credits as the web interface, with no subscription required. Authentication uses API keys from your account dashboard. For detailed endpoints, rate limits, and code examples, visit the JAI Portal API documentation or contact support for enterprise onboarding and volume discounts.
