Best Practices

Crafting Effective Prompts

Be Specific and Descriptive:

• Include camera angles (close-up, medium shot, wide shot, aerial view)
• Specify lighting conditions (golden hour, moonlit, studio lighting)
• Describe mood and atmosphere (tense, cheerful, mysterious)
• Include audio elements in your description
• Mention timing and pacing when relevant

Example Effective Prompt: "A medium shot of a wise owl circling above a moonlit forest clearing at night, wings gently flapping. The camera follows the owl as it descends to a forest path. Audio: soft wing flaps, distant owl calls, gentle wind rustling through trees, and a light orchestral score with woodwinds."

Camera Control Examples:

• "tracking shot following a runner through a park"
• "slow dolly zoom on a city skyline at sunset"
• "handheld camera walking through a crowded market"
• "crane shot rising above a mountain landscape"

Using Reference Images

Best Practices:

• Choose clear, well-lit images showing the subject from desired angles
• Provide 1-3 images for optimal guidance
• Ensure consistent lighting and quality across references
• Use images that clearly show distinguishing features
• Match reference style to desired output aesthetic

Reference Types:

• Character references: Close-up portraits showing facial features
• Style references: Images demonstrating desired artistic treatment
• Asset references: Clear product shots or object views

Image-to-Video Tips

Optimal Input Images:

• Use high-quality, high-resolution source images
• Ensure clear subject focus and good composition
• Avoid overly complex or cluttered backgrounds when possible
• Match image aspect ratio to desired output

Prompt Strategy:

• Describe the motion and action, not just what's in the image
• Focus on what should happen, not what's already visible
• Specify camera movements and transformations
• Include audio descriptions for complete scenes

Audio Considerations

Guiding Audio Generation:

• Describe specific sounds: "footsteps on gravel," "car engine starting"
• Request ambient audio: "city traffic in the distance," "ocean waves"
• Specify music style: "upbeat jazz," "dramatic orchestral score"
• Include dialogue cues: "character speaks nervously"
• Mention audio transitions: "music fades as dialogue begins"

Audio Best Practices:

• Be specific about sound types and intensity
• Consider how audio complements visual action
• Use audio to enhance mood and atmosphere
• Audio is automatically synchronized but can be guided with clear descriptions

Frame Control

First & Last Frame Generation:

• Ensure start and end frames are visually compatible
• Request physically plausible transitions
• Consider natural motion sequences
• Match lighting and color grading between frames
• Works best with logical motion progressions

Scene Extension:

• Plan for continuity when extending clips
• Consider how audio will continue across extensions
• Best for extending establishing shots and ambient scenes
• Each extension builds on the final second of previous clip
