Crafting Effective Prompts for LTX Video
When writing prompts, focus on detailed, chronological descriptions of actions and scenes. Approach it like a cinematographer meticulously describing a shot list, ensuring the scene flows naturally and vividly in one cohesive paragraph. Start directly with the main action, ensuring descriptions are literal and precise. Use the following structure for optimal results:
- Main Action: Begin with a single sentence summarizing the key event or motion.
- Movements and Gestures: Add specifics about how characters or objects move and interact within the scene.
- Appearance: Describe the physical traits or textures of characters and objects with clarity.
- Environment: Include detailed descriptions of the background, setting, and atmosphere.
- Camera Work: Specify angles, focal lengths, and movements (e.g., zoom-ins, tracking shots).
- Lighting and Colors: Set the mood by detailing lighting sources, shadows, and color palettes.
- Dynamic Changes: Note any transitions, sudden movements, or impactful shifts.
Example Prompt
„A lone cyclist races down a winding mountain trail, the gravel crunching beneath their tires as pine trees blur past. The rider’s red jacket flutters in the wind, contrasting sharply against the green canopy. The camera tracks from a low angle, capturing the rider’s determined face and the dirt spraying from the wheels. In the background, a golden sunset casts long shadows across the trail, illuminating the dust in the air. As the rider rounds a sharp bend, the camera pans to reveal a distant valley shrouded in mist.”
🎮 Parameter Guide
- Resolution Preset: High for intricate detail, low for faster scenes.
- Seed: Save seeds to recreate specific aesthetics.

LTXV Prompt Structure Analysis
The provided text-to-video prompts demonstrate a structured and detailed approach to crafting scenes for video generation. Each prompt effectively combines elements of action, description, and environment to create visually rich, realistic outputs. Here’s an analysis of their structure and key components:
1. Main Action
Each prompt begins with a clear, primary action or setting to anchor the scene.
- Example 1:
„A young woman in a traditional Mongolian dress is peeking through a sheer white curtain, her face showing a mix of curiosity and apprehension.” - Example 2:
„A young man with blond hair wearing a yellow jacket stands in a forest and looks around.”
Purpose: Starting with the action sets the tone and immediately provides context for the video. It introduces the character, their behavior, or a defining activity.
2. Character/Subject Description
Detailed descriptions of the characters or subjects follow the main action, including physical appearance, clothing, and unique features.
- Example 1:
„The woman has long black hair styled in two braids, adorned with white beads, and her eyes are wide with a hint of surprise. Her dress is a vibrant blue with intricate gold embroidery, and she wears a matching headband with a similar design.” - Example 2:
„He has light skin and his hair is styled with a middle part.”
Purpose: This step ensures the generated video accurately reflects the intended details, creating a specific and vivid visual image.

- Example 1:
„The background is a simple white curtain, which creates a sense of mystery and intrigue.” - Example 2:
„The background is slightly out of focus, with green trees and the sun shining brightly behind the man.”
Purpose: Adding environmental details ensures the scene feels immersive and well-rounded, complementing the subject.
4. Camera Angle and Movements
Camera positioning and actions are explicitly mentioned to guide the framing and composition of the video.
- Example 1:
„The camera angle is a close-up, focused on the woman with brown hair’s face.” - Example 2:
„The camera angle is low, looking up at the man, and remains stationary throughout the video.”
Purpose: Specifying camera work helps the AI create videos that mimic cinematic techniques and desired perspectives.
5. Lighting and Atmosphere
Lighting conditions and their effects on the scene are described to establish mood and realism.
- Example 1:
„The lighting is warm and natural, likely from the setting sun, casting a soft glow on the scene.” - Example 2:
„The lighting is natural and warm, with the sun creating a lens flare that moves across the man’s face.”
Purpose: Describing lighting adds dimension and emotional tone to the scene, enhancing its realism.
6. Additional Effects or Changes
Dynamic elements, such as lens flares, changes in subject movement, or focus shifts, are included to make the scene more engaging.
- Example 1:
There’s a sense of mystery from the woman peeking through the curtain. - Example 2:
„The sun creating a lens flare that moves across the man’s face.”
Purpose: These elements introduce subtle motion or atmospheric shifts, creating a more dynamic and visually compelling output.
