Prompts to copy and change
- Colourful balloons floating up against a blue sky, camera tilting up
- A birthday cake with lit candles on a table with party lights, slow push-in
- Confetti falling in slow motion with bright colours, studio light
- Gift boxes with ribbons on a wooden table, soft daylight, slow zoom in
- A party table with cupcakes and streamers, camera gliding past
- Sparklers glowing in the dark in a garden, warm light
Add a voiceover to your birthday videos video
Switch Sound to Voiceover and paste a script. Each example below shows what it would cost.
- "Happy birthday! Wishing you a day full of laughter, cake and everything you love." That script is 14 words, so the video falls in the "6–10 seconds" length and costs 2 credits in Full HD or 4 credits in 4K.
- "Another year, another reason to celebrate. Today is all about you, so enjoy every single minute." 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.
