Best Practices

Prompt Engineering for Video

Include motion and action:

“A car driving down a winding road”
“Waves crashing on the shore”
“A bird flying through the sky”

Specify camera movement:

“Smooth camera pan across the landscape”
“Drone shot flying over the city”
“Tracking shot following the subject”

Describe timing and pacing:

“Slow motion water droplets falling”
“Fast-paced city traffic”
“Gentle floating motion”

Video Optimization

Keep prompts concise but descriptive (under 200 characters recommended)
Specify duration based on your needs (5s for social media, 10s for detailed scenes)
Choose aspect ratio to match your platform (16:9 for YouTube, 9:16 for TikTok/Instagram)
Use seeds for consistent variations

Pricing

Video generation is billed per second of output. Contact us for detailed pricing based on your usage volume.
