LTX 2.3 Prompt Engineering Best Practices from Community

The LTX 2.3 community has discovered specific prompt patterns that consistently produce higher-quality videos. This guide compiles the most effective techniques.

Camera Movement Descriptors

Effective patterns:

• "camera slowly dollies in" - smooth forward movement
• "jib up from ground level" - crane shot upward
• "gentle pan right" - horizontal camera rotation
• "orbit around subject" - circular camera path

Avoid:

• Vague terms like "dynamic camera" or "interesting angle"
• Multiple conflicting movements in one prompt
• Camera speeds without context ("fast pan" vs "whip pan")

Motion Control

High success rate:

• "subtle wind blowing hair" - natural micro-movements
• "waves gently lapping shore" - repetitive motion
• "character turns head slowly" - controlled action

Common failures:

• "everything moving" - causes chaos
• "fast action" without specifics - unpredictable results
• Complex multi-object choreography - often fails

Lighting and Atmosphere

Works well:

• "golden hour sunlight" - specific time of day
• "soft diffused lighting" - quality descriptor
• "rim light from behind" - directional lighting

Problematic:

• "dramatic lighting" - too vague
• Multiple light sources without hierarchy
• Conflicting atmosphere terms

Technical Quality Descriptors

Recommended:

• "high detail architecture" - emphasizes sharpness
• "crisp focus on subject" - depth of field control
• "smooth 24fps motion" - frame rate specification

Skip these:

• "4K" or "8K" - model ignores resolution terms
• "photorealistic" - often counterproductive
• "professional" - meaningless to model

Prompt Structure

Optimal format:

1. Subject (what)
2. Action (movement)
3. Camera (perspective)
4. Lighting (atmosphere)
5. Technical (quality)

Example: "Ocean waves crashing on rocky shore, camera slowly pans right, golden hour sunlight, high detail water physics, 25fps"

Common Pitfalls

Artifact triggers:

• Overly long prompts (>100 words)
• Contradictory instructions
• Abstract concepts without visual anchors
• Multiple subjects with different actions

Quality killers:

• Wrong aspect ratio for content
• CFG scale above 5.0
• Insufficient context for complex scenes

Community Tips

• Test prompts at low resolution first
• Keep CFG between 3.0-4.5 for most cases
• Add "smooth motion" for better temporal consistency
• Specify frame rate explicitly
• Use reference images when possible
