Biker Birthday Cake Kling prompt you can paste
Updated:
Short answer
Paste the paragraph into Kling's main box and the negative line into the box below it, add your photo and choose 9:16. Kling does not offer exactly 7 seconds, so this version runs 10: the arrival is slower and the freeze at the end lasts longer. Plan on several attempts.

Paste-ready paragraph and negative prompt
A vertical 9:16 video of 10 seconds, shot in the first person. Two hands at the bottom of the frame hold out a round dark chocolate birthday cake with glossy icing, a few gold chocolate decorations and seven tall, thin lit candles at chest height. The cake carries no writing, letters or numbers. The camera is handheld but steady and never cuts. The setting is a wide, empty, rain-soaked waterfront car park at night, a long line of city lights across the black water, wet tarmac reflecting them. For the first three seconds the candles flicker while one motorcycle headlight, far across the car park, streaks straight toward the lens. A plain black sport motorcycle with no emblem or badge swings in and stops sideways just behind the cake, and its rider, in a plain glossy black full-face helmet, turns to the camera and pulls the helmet off with both hands. The rider is the person or pet from the reference photo, with face, hair, skin tone and clothes exactly as pictured. Hair moves in the wind, the helmet goes under one arm, and the rider smiles, leans in and blows out every candle in one breath, leaving thin smoke. In the last two seconds the colour fades to black and white and the picture slows to a near freeze on the smiling face. Sound: soft night ambience, an engine arriving and idling, a mellow instrumental swell as the flames go out. No singing, no lyrics, no speech, and no text or watermark on screen. Negative prompt: brand names, logos, badges, lettering or numbers on the bike, helmet or cake, subtitles, watermark, voices, singing, birthday song, extra people
Using Kling's two boxes
- The paragraph is for the main prompt box and the last line is for the negative field. Keep the "no" words out of the paragraph, since Kling reads the two apart.
- Pick ten seconds. If you only have 5, drop the hair flick and let the helmet come off straight away.
- Add the greeting and the sound after rendering. Never upload a celebrity's picture.
Questions people ask
Why does the text insist on no brand names?
Video models love to put real motorcycle and helmet logos on things. Describing the bike as plain and listing brand names in the negative box keeps them off.
Will the sound line up?
Only roughly. At ten seconds the beats sit later than in the 7-second original, and nothing in the text pins them to a track.
Is a song or a real person named in it?
No. The prompt covers the scene only. No song, artist or real person is named.
