Best Practices

Write Clear Prompts

Choose the Right Media Type

Use ai-images for educational content, gameplay for gaming, custom media for brands.

Match Voice to Content

Choose a voice that fits your content tone - energetic for gaming, professional for business.

Use Webhooks

Always use webhooks in production instead of polling for video status.

Prompt Writing Tips

Good Prompts

“Create an engaging video about the top 5 productivity tips for remote workers. Target busy professionals and use a motivational tone.” “Explain how blockchain technology works using simple analogies. Make it beginner-friendly and include real-world examples.” “Share 3 mind-blowing facts about space that most people don’t know. Hook viewers in the first 3 seconds.”

Avoid

“Make a video” (too vague) “Video about stuff” (no direction) “Something interesting” (unclear intent)
