Turns static visuals into cinematic motion with synced audio and natural camera flow
LTX 2 Fast Text-to-Video prioritizes fast text-to-video generation. It generates video clips from text prompts significantly faster than the Pro model, allowing for rapid iteration and real-time experimentation. Use this mode to explore concepts, test prompts, and create drafts with our fast text-to-video generation engine before finalizing with high-fidelity generation.
Fast mode is the perfect starting point for the Retake workflow:
1) Rapidly generate multiple variations with fast text-to-video generation to find the best motion or composition.
2) Select your favorite clip.
3) Send it to Retake to refine, upscale, or adjust specific elements: LTX 2 Retake Video

It is engineered for speed. While Pro focuses on maximum fidelity, Fast Text-to-Video minimizes latency, allowing you to generate and view video concepts in seconds. It's the best choice for fast text-to-video generation when time is the priority.
Yes. You can still select up to 2160p (4K) resolution and enable audio generation. However, increasing resolution to 4K will naturally increase generation time compared to the lightning-fast text-to-video generation 1080p baseline.
Use it for rapid brainstorming, prompt testing, storyboarding, and creating quick social media drafts. It allows you to iterate on ideas quickly with fast text-to-video generation before committing to a final high-fidelity render.
Indirectly, yes. Use fast text-to-video generation to lock in your prompt and composition. Then, use the same prompt and seed in the Pro Text-to-Video workflow, or take your Fast result into the Retake Video tool for refinement.
Fast mode supports standard durations (6s, 8s, 10s) and extended durations up to 20s. Note that durations above 10 seconds are currently optimized for 1080p resolution and 25 FPS to ensure successful fast text-to-video generation.
Yes, the audio generation capability is identical. The "Fast" designation applies to the video generation steps and optimization, not the audio synthesis.
