What makes a good ocean and underwater prompt
Underwater prompts rely on light rays and slow movement. Describe the colour of the water, the creatures and the camera drift.
Prompts to copy and change
- A coral reef with colourful fish and light rays from above, camera slowly gliding
- A sea turtle swimming in clear blue water, slow motion, side view
- Bubbles rising through deep blue water with sunbeams, macro
- A school of fish moving in unison in a sunlit current, wide shot
- A diver silhouette descending along a wall of coral, camera following
- Jellyfish drifting in dark water with soft glowing light, slow zoom in
Add a voiceover to your ocean and underwater video
Switch Sound to Voiceover and paste a script. Each example below shows what it would cost.
- "Beneath the surface, a different world is waiting. Dive in." That script is 10 words, so the video falls in the "Up to 5 seconds" length and costs 1 credit in Full HD or 2 credits in 4K.
- "Explore reefs, wrecks and the quiet blue. Our dive trips leave every morning from the harbour." That script is 16 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 the water colour
- Add light rays for depth
- Calm music
