そのまま使えるAI Birthday Video Promptsのプロンプト集
“A cosy living room in warm evening light. A homemade chocolate cake with five lit candles on a wooden table, balloons and paper streamers around it. The camera pushes in slowly as the flames flicker and confetti falls softly in front of the lens. No people, no text, no writing on the cake.”
“A hallway at dusk. A front door opens and a warm room full of balloons and fairy lights is revealed, a table with a cake and small gifts at its centre. Slow push-in through the doorway, soft golden light, gentle party sounds, no people, no text.”
“A sunny garden birthday party: a long table with a white cloth, a tiered cake, bunting between two trees, petals drifting in the breeze. Slow dolly along the table, bright afternoon light, birdsong, no people, no text, no logos.”
AI Birthday Video Promptsとは？
An AI birthday video is a short generated clip made to be sent to someone on their birthday. It can be a candle moment, a surprise reveal, a decorated table or a whole party scene. The point is warmth, not spectacle.
Video models do best with a single, clearly described moment. “A cake with lit candles and falling confetti” gives them everything they need. “A full party with dancing, speeches and fireworks” gives them too much to track and usually produces mush.
Because the clips are short and self-contained, they fit a text message, a story post or the first slide of a card. Add your own caption or message when you send it.
プロンプトをコピー
“A cosy living room in warm evening light, photorealistic. A homemade chocolate birthday cake with five lit candles sits on a wooden table, surrounded by colourful balloons and paper streamers. The camera pushes in slowly toward the cake as the candle flames flicker, then a burst of confetti falls softly in front of the lens. Warm golden light, gentle party ambience, no people, no text, no writing on the cake, no logos.”
01
The one-moment rule
Pick one thing that happens, and describe only that.
- The candle moment
- A cake, lit candles, flickering flames. The classic, and the easiest for a model.
- The surprise reveal
- A door opens onto a decorated room. The camera movement carries the surprise.
- The confetti burst
- Confetti falling softly in front of the lens works as an ending beat for any of the above.
02
Make it feel warm
The words that matter most are about light and pace.
- Golden light
- “Warm evening light,” “soft golden light,” “fairy lights.” Cold white light kills the mood.
- Slow camera
- A slow push-in or a gentle dolly. Fast moves feel like an advert, not a gift.
- Small, real objects
- A cup of tea, a book, a streamer on the floor. Little details make a scene feel lived-in.
03
Make it personal without putting a name on screen
Video models cannot spell reliably, so the personal touch belongs in your own caption.
- Match the number of candles
- Write “five lit candles” for a five-year-old. A count of candles is something a model can follow; a number-shaped candle is lettering, and it goes wrong.
- Match their taste
- A lemon cake, a garden, a bookshop. Pick a setting the person would love.
- Add your own message
- Type the greeting in your messaging app or editor. It always spells correctly.
04
What to leave out of the prompt
A few choices lead to garbled results or trouble when you post.
- Writing on the cake or banner
- Models invent random letters. Say “no writing on the cake” and “no text.”
- Cartoon characters and brand cakes
- Name the colour and shape, never a character or a brand. It avoids copyright trouble.
- Real people’s faces for strangers
- Use an object scene, or upload a photo only of someone who agrees to it.

AI Birthday Video Promptsのよくある質問
A short generated clip made to send as a birthday gift, usually a candle moment, a surprise reveal or a decorated table.
MiniMax H3 reaches up to 4K and handles warm light and candle flames well; Seedance 2.5 adds generated audio such as soft party sounds. Either works from the same chat.
Yes, if they agree. Upload a clear photo as the opening frame and describe the moment around them. For a surprise, an object scene is a safer first try.
Add it as a caption in your messaging app or video editor after you download the clip. Models cannot spell reliably, so avoid asking for text in the video itself.
Five to eight seconds is plenty for one moment. MiniMax H3 offers 5 to 15 seconds per render and Seedance 2.5 goes up to 30 seconds.
Yes. Keep the same room and light, change the moment each day: candles, a doorway, a garden table. A consistent look makes the clips feel like one set.
