Short answer: to make an AI birthday video from a photo, upload a clear photo of the birthday person to an image-to-video model and describe one warm action, such as "she smiles, blows out the candles and laughs". In Dora that takes a few minutes: choose a model that accepts photos, write the prompt, pick a vertical shape and generate a 4 to 6 second clip.

Birthday guides from other tools follow the same recipe: pick photos with personal meaning, animate them with moderate motion, then add a message and music (Morphic, Dreamina). Here it is with Dora's real controls, plus a way to make the photo say happy birthday in your own voice.

Step 1: Choose the photo

  1. Use a sharp, front-facing photo with even light and the whole face visible.
  2. One person is the safest start. Groups give the model more faces to get wrong.
  3. Pick a photo with a bit of room around the person if you want a wave or a hug; a tight close-up can only smile or blink.
  4. A scan of an old print works too. If it is faded, clean it first with the steps in how to restore and animate old photos.

Step 2: Decide what the clip does

  • A smile and a wave: the simplest and the most natural.
  • Blowing out candles: a birthday cake in the photo helps; otherwise describe it.
  • A speaking or singing greeting: use Lip Sync (step 4).
  • Birthday scene: the same person at a party with balloons. Same Character takes up to 7 photos of one person and places them in any scene you describe.
  • A pet's birthday: see how to make an AI video of your pet.

Step 3: Make the video in Dora

  1. Open the create page and switch to video.
  2. Pick a model that accepts a photo. Seedance 2 Mini, Kling 3.0 Turbo, Kling Omni and Gemini Omni all do. The models page shows each one's cost in coins before you spend anything.
  3. Upload the photo.
  4. Write the prompt: subject, one action, mood and camera (examples below).
  5. Choose 9:16 for Stories, Reels and messaging apps, or another shape if you need it.
  6. Keep it to 4 to 6 seconds, then generate. The clip lands in your gallery, where you can download it.

Step 4: Make the photo say happy birthday

On the web app, Lip Sync animates a face from a still photo plus an audio track, so the mouth follows your recording. The audio must be 15 seconds or shorter, which fits a greeting.

  1. Record a short message on your phone: "Happy birthday, Mum! Sorry I can't be there, big hug."
  2. In Dora's web app choose Lip Sync, upload the photo and the audio.
  3. Pick 9:16, 16:9 or 1:1 and 480p or 720p, and generate.

You can also record yourself singing one line. For a longer greeting, make several clips and join them in your phone's editor. More on the options in how to make a talking AI avatar.

Birthday prompts to copy

  • Smile and wave: "The woman in the photo smiles warmly and waves at the camera, soft indoor light, slight push-in. Keep her face the same."
  • Candles: "He leans in and blows out the candles on the cake, smoke rises, he laughs, warm light, static camera."
  • Balloons: "Colorful balloons drift upward behind her as she looks up and smiles, gentle handheld camera."
  • Party scene (Same Character): "The same person laughs at a table with a birthday cake and friends clapping, warm evening light, slow tracking shot."
  • Pet: "The dog sits wearing a small party hat and wags its tail, confetti falls, static camera."

Say what must stay: "keep the face and the background the same".

Make it look better

  1. One action per clip. Waving, blowing candles and laughing in four seconds will blur together. Make three clips.
  2. Gentle motion. Morphic warns that very heavy motion can distort faces, and in our experience subtle movement reads as more real.
  3. Try two models with the same photo and keep the better take.
  4. Add a song or voice in your editor; Dora makes the visuals, not the final cut.
  5. Check the face against the original photo before you send it.

What can go wrong

  • Faces drift. The more the prompt changes, the more the face can change. Shorten the clip or simplify the action.
  • Candles and cakes. Small objects and any lettering on a cake are weak spots. Do not rely on a readable "Happy Birthday" in the picture.
  • Lip Sync needs a clear face. A turned head or a hand over the mouth gives poor results.
  • Consent. Only use photos of people who agree, and be careful with photos of people who have died; some relatives find it moving, others upsetting.
  • Labels. If you post publicly, TikTok asks creators to label AI-generated content that shows realistic-looking people (TikTok Community Guidelines).

Other tools for birthday videos

Dora is a general generator with no birthday template pack. If you want a guided look, these are worth trying:

Where Dora is different: you choose from several video models, you write the prompt, and the cost in coins is shown before each generation. Where template tools are better: a finished look with music and no prompt writing.
