How to Make a Birthday Rap Video From Two Photos

The topic box takes 120 characters, and the Birthday button fills in “Happy birthday, ” for you. Add three things: the name, the age or milestone, and one detail that is theirs. One idea works better than a list of jokes: a 12-second rap has room for a few lines.

• For a best friend: “Maya turns 30 and still cannot parallel park”
• For a partner: “Happy birthday Sam, ten years of stealing my hoodies”
• For a grandparent: “Grandma Rose turns 70 and still beats me at Mario Kart”
• For a sibling: “Leo turns 18, the brother who eats every leftover”
• For a coworker: “Happy birthday Priya, queen of the 9 am standup”
• For a Halloween birthday: “Jess turns 25 on Halloween, born for costume parties”

These are topics we wrote for this guide, not results we tested. The model is asked to rap in the language of the topic, so a Spanish topic asks for a Spanish rap.

1. Open the birthday rap song page. Its generator starts on AI rap with Seedance 2.0 Mini, 720p, 12 seconds and 9:16.
2. Put the birthday person on the left to rap, or yourself on the left to deliver the wishes. The right photo hypes.
3. Pick a stage: Hotel Lobby is the orange booth; Luxury Lobby, Studio Booth and Street Cypher are other sets at the same price.
4. Tap Change on the sound row, type the topic and tick Both rap (trade bars) if you want to answer each other.
5. Tap Create video and check the credits on the button. Sign in with Google the first time.
6. Watch the whole video before you send it, then tap Download MP4.

On the Hotel Lobby stage, the AI is asked for a new beat in the rhythm of the Hotel Lobby track, with new words and without the original melody or voices. The other stages each have a beat of their own.

Our render

Made on this website on October 3, 2026, with two AI-made people. The topic was only the Birthday button’s “Happy birthday,” with no name, and Both rap was on, so the grandson raps back. It was made before the beat change of October 5, so a new video will have a different beat.

• Listen for the name. We have not measured how often names come out right, so check it. If it matters, record the message yourself.
• Check that your detail made it in. A short, concrete detail (a game, a food, a habit) leaves less to guess than a long story.
• Look at both faces in a few frames, especially when someone turns.
• Every new try costs the same credits again. A render that fails is refunded automatically; a finished video you do not like is not.

Record the wishes with your phone’s voice recorder, then pick Your song on the own song page. The person on the left lip-syncs 2 to 15 seconds of it in the booth. The steps, from Voice Memos to the upload, are in turn a voice note into a Hotel Lobby video.

• Make it a day ahead, so there is time for a second version.
• Keep 9:16 for stories, TikTok and Reels; send the MP4 straight to a group chat.
• On TikTok, turn on the AI-generated label. TikTok does not allow AI content showing anyone under 18 (TikTok), so keep a kid’s birthday video to family chats.
• On iPhone, the download goes to Files first. How to save it to Photos.
