What makes a good space and planets prompt
Space prompts should name the object and the scale. Describe the colours, the light source and a slow, wide move.
Prompts to copy and change
- A blue planet with rings and a small moon with sunlight glinting, slow drift
- A glowing purple nebula with scattered stars, camera slowly moving forward
- An astronaut silhouette floating in front of a bright Earth, slow rotation
- A comet with a long tail crossing a starfield, wide shot
- A spaceship passing a red desert planet at sunrise, slow tracking
- A telescope under a starry sky with a faint glow, slow tilt up
Add a voiceover to your space and planets video
Switch Sound to Voiceover and paste a script. Each example below shows what it would cost.
- "The universe is bigger than any story we tell. Let us start exploring." That script is 13 words, so the video falls in the "6–10 seconds" length and costs 2 credits in Full HD or 4 credits in 4K.
- "Look up tonight. The stars are closer than you think, and our observatory is open for everyone." That script is 17 words, so the video falls in the "6–10 seconds" length and costs 2 credits in Full HD or 4 credits in 4K.
Tips
- Name colours of the nebula or planet
- Wide shots for scale
- Cinematic music
