How to Write a Great LTX 2.3 Fast Prompt
LTX 2.3 Fast is a generate-first engine, so keep the prompt short, visual and direct.
Tip: the UI already handles duration, aspect ratio, resolution, fps and the long-duration routing constraint. Focus the prompt on one subject, one move and one mood.
How LTX 2.3 Fast uses references
Text prompt
Test subject, style, camera and format instructions with short prompt variants.
Start image
Use image-to-video when a visual seed should define composition or product framing.
Vertical draft
Frame early social concepts around 9:16 or 16:9 review needs.
Look comparison
Run prompt variants to compare lighting, color and motion direction.
Production handoff
Move the strongest draft into the appropriate final route once the concept is clear.
Quick prompt (fastest draft)
Use this for rapid variants and hook testing.
[Subject + one action], [camera move], [lighting/style], [optional sound cue], [16:9 or 9:16 vibe].
EXAMPLE
[Subject + one action], [camera move], [lighting/style], [optional sound cue], [16:9 or 9:16 vibe].
Global principles
- One subject, one action and one move beat longer wish-list prompts.
- Use start images for identity and prompts for motion.
- Reserve 12 to 20 second runs for cases where the extra pacing room really matters.
Engine quirks / what to watch for
- Fast responds well to concise prompts.
- Image-to-Video works best when the still already contains the desired composition.
- Start/end image transitions are most reliable when the two frames are clearly related.
Demo prompt - fast cinematic draft

A powerful boxer walks alone through a dark arena tunnel toward the ring, athletic frame wrapped in a hooded robe, shoulders relaxed but dangerous. Low front tracking shot, slow push-in, hard rim light, drifting haze, muted crowd rumble and one sharp impact cue, 10 seconds, 16:9.

Practical strengths and boundaries
Best practices, common fixes, and important limitations to help you get the strongest results with LTX 2.3 Fast.
What works best
- Good cost/speed balance for concept exploration, hook testing and aspect-ratio variants.
- Useful when you want a lighter-weight LTX page without extend/retake complexity.
- Start/end image support makes it practical for simple transformation cuts and reveal transitions.
Common problems → fast fixes
- Longer runs look less flexible -> keep >10 second clips only for cases where the extra length is worth the 1080p/25 fps cap.
- Image-to-Video feels weak -> improve the start image composition before adding more prompt detail.
- Start-to-end transition feels forced -> make the end image closer to the same visual world.
- The clip feels too busy -> reduce to one action and one camera move.
- You need source-video editing -> move to LTX 2.3 Pro instead of overloading Fast.
Hard limits to keep in mind
- No Audio-to-Video, Extend or Retake on the Fast route.
- Durations above 10 seconds are constrained to 1080p at 25 fps.
- Fast is best used for generation, not source-video repair workflows.

Fast is optimized around Text-to-Video and Image-to-Video only. It is the easiest LTX 2.3 entry point when the goal is to test more ideas, faster.
- Use Text-to-Video for broad ideation.
- Use Image-to-Video when the first frame or product identity matters.
- Use 9:16 for social-first variants.
- Keep the prompt focused on one motion beat.
What Fast does not include
The product boundary is important for clear UX. Audio-to-Video, Extend and Retake stay on LTX 2.3 Pro so Fast remains simpler and more predictable.
