Dad across the cuts
One uploaded adult identity follows the birthday protagonist from doorway to cake table.
The selected birthday gathering
The cake table, doorway surprise and family cake-sharing montage in the reference’s first 15 seconds.
His face in the family birthday montage
Happy Birthday Dad AI Video replaces the older birthday protagonist in a short family celebration. The reference moves between the cake table, his surprised entrance through the curtain and family members offering a bite.
One adult photo follows that same central person across the cuts. Dad’s face, hair, build and visible clothes come from your photo; the room, balloons, cake, expressions, camera and birthday gestures follow the selected reference.
Only the first 15 seconds are used, at the original pace. The download is a vertical 9:16 MP4 at 720p with the sound from that exact window. Other people in the family scene keep their reference identities.
A curtain entrance and a cake shared with family
This selected take is a montage. It opens at the cake, cuts to the birthday person coming through the patterned doorway curtain, returns to the table and ends within the family cake-sharing sequence. It does not become one invented continuous shot.
The older birthday protagonist stays the same person in every scene, including when hands, cake or other family members partly hide the face. Your single portrait maps to that role rather than to every adult who appears.
The woman beside the table and the younger relatives remain in their existing roles. Their faces, hands and body positions are kept separate from Dad’s identity as they stand near him or feed a bite of cake.
The yellow gift box, gold star balloons, silver tinsel, tablecloth and existing cake decoration stay fixed. The page has no name, age, note-writing or custom-speech controls. Add the words you want him to read when you send the video.

- Use one adult photo with an unobstructed face and natural lighting.
- Pick a photo that shows the outfit you want at the birthday table.
- Avoid heavy face filters, sunglasses hiding the eyes or a group portrait.
- Watch the first 15 seconds: the curtain, cake and reference family are fixed.
- Only upload yourself or adults who agreed to appear. Do not use photos of celebrities, public figures or strangers.
Birthday video for Dad questions
How can I make a happy birthday dad video from his photo?+
Upload one clear adult photo of Dad with his permission, confirm the consent box and generate the curtain-surprise scene. The saved MP4 follows the selected birthday montage for 10 credits.
How many family photos should I upload?+
Only one photo for the older birthday protagonist. The reference relatives keep their own identities; this page does not replace the whole family.
Which person gets Dad’s face?+
The older birthday adult who appears through the patterned doorway curtain and beside the cake. That same identity stays bound to him across the cuts, even during brief occlusion.
What happens in the birthday montage?+
It opens at the cake, shows the birthday adult entering through the curtain, returns to the table and continues into family members offering cake. The output uses the first 15 seconds rather than the longer original clip.
Will the clothes in his photo be used?+
Yes. His face, hair, body appearance and visible clothing come from the uploaded photo. The birthday reactions, moving pose and hand contact follow the reference.
Can I change the cake, age or room?+
The cake decoration, yellow gift box, balloons, tinsel and room stay with the selected reference. This page does not have age, name, text or room-upload controls.
Does it make a spoken birthday message for him?+
It restores the sound of this exact reference window. It does not create new dialogue or say a custom name. Send a personal message alongside the downloaded video.
How long is the video?+
The selected window is 15 seconds at the original pace. The result is a vertical 9:16 MP4 at 720p with matching reference sound.
Can I make it for another consenting adult?+
Yes. Use this scene when the older central birthday role and reference family gathering fit the occasion. Every uploaded person must be an adult who agreed to appear.
Is the birthday video for Dad free?+
Each generation uses 10 credits. Preview playback is free. A low balance opens the credit-pack dialog before generation or input upload starts.
What if the task fails or I leave the page?+
Open this template again or visit My creations to read the saved task. A confirmed failure shows the error and returns the generation credits; reopening does not create another paid task.
