AI Birthday Video Maker — their photo, moving, with a song that sings their name

Video models redraw every frame, and lettering is the hardest thing for them to keep steady. So make the card as a still first, where you can check every letter, and use it as the end frame of the intro. Google's Veo 3.1 documentation describes exactly this set-up — a start image plus an optional end image, with the video generated between them ^[2]. In Kenerate the “End frame” slot is on Wan 3.0, Seedance 2.0 and Veo 3.1 Fast. For a name that must never wobble, add it as a text layer in your editor instead.

All four music families in Music Studio can sing; they differ in length and price:

• Ken Music 1.5 (30 credits): full songs with vocals up to about 3 minutes, Song mode writes the lyrics, Lyrics mode sings yours. It can also take an image — the card — to inspire the track.
• Ken Music 1 (12 credits): quick clips of about 30 seconds, enough for a short greeting.
• ElevenLabs Music v2.5 (225 credits per started minute): set the exact length, from 10 seconds, to match the video.
• Mureka V9.5 (68 credits) and MiniMax Music 3.0 (45 credits): more choice of style and vocal.

Animating a friend's or partner's photo for a private greeting is a common, kind thing to do — but it is their face. Use a photo they shared with you or that you took together, keep the motion warm and true to them, and don't post it publicly without asking. Never animate photos of strangers or public figures.

Kenerate's birthday videos are for grown-ups and pets. The content filter blocks prompts about children and ages under 18 in video, music and voice, so this page offers no ideas for children's parties.

From each vendor's own page, read on 24 October 2026 ^[3][4]:

• HeyGen: a name, photos and a message; it writes the script, can animate a photo to speak and offers a music library; it suggests 15–45 seconds and has a free plan, but lists no prices and says nothing about consent for photos.
• InVideo: a prompt plus your photos, AI voice-over in 50+ languages and background music; it doesn't state a length or offer a sung birthday song.
• Kenerate: you build the card, the moving photo and a song that sings the name, pick the model and length, and see the credit price before each render.

For decades a music publisher collected licence fees for the song. In 2015 a US federal judge ruled the publisher held no valid copyright in the lyrics, and his final order in 2016 declared the song in the public domain in the United States ^[1]. You can paste the words into Lyrics mode; the engine still writes its own melody.

A festive birthday card: gold and blush balloons, falling confetti and soft bokeh lights on a cream background. The words “Happy 40th, Maya” in large elegant gold script, centred and fully legible. No other text.

Confetti falls and the balloons drift gently upward as the greeting appears and settles, sharp and still for the last second. Static camera. The text never changes. Sound: a soft party pop and light chimes.

She smiles warmly and laughs, looking at the camera, as gold confetti drifts down around her and warm party lights glow in the background. Slow, gentle push-in. Her face and features stay the same.

He raises a glass with a big smile and says: “Happy birthday, Sam — here's to forty more!” Warm living-room light, soft cheering in the background, static camera.

Upbeat acoustic pop happy birthday song for Maya who is turning 40, sing her name Maya in the chorus, warm female vocals, ukulele and handclaps, joyful and a little funny, about one minute.

The dog wears a small paper party hat, wags its tail and tilts its head at the camera while colourful confetti falls. Bright, cheerful room, static camera.
