Birthday Drive-By AI Video

Birthday Drive-By replaces the driver in a candle-blowing birthday scene. The car approaches a handheld cake on a wet evening street; the camera movement, cake, candle action and final birthday edit follow the source video.

How to create this video

  1. Upload one clear photo of the woman or man who should appear in the driver’s seat.
  2. Optionally upload a car photo, choose your resolution and generate.
  3. Choose 480p, 720p or 1080p. Review the credit cost, then generate and view the result in Studio.

Reference order

@Image1 is the person. @Image2 is the optional car. Without a car photo, the original vehicle stays. The 7.17-second source is billed as 8 whole seconds.

Frequently asked questions

How do I make a Birthday Drive-By video?

Upload one person photo, optionally add a car photo, select 480p, 720p or 1080p, then generate with Higgsfield Genjutsu.

Can I use a woman or a man as the driver?

Yes. The required person reference replaces the main driver. Use a clear, well-lit photo with a visible face; exact identity reproduction is not guaranteed.

Do I have to upload a car photo?

No. The car input is optional. Leave it empty to preserve the original vehicle, or upload a clear car photo to request a replacement.

Which reference belongs to each input?

The person is @Image1 and the optional car is @Image2. These references replace the driver and vehicle respectively, not the cake or background.

Can I change the cake, candles or background?

This template has no cake or background input. It preserves the source birthday cake, candle-blowing sequence and wet evening street.

What does this template cost?

The 8-second billing duration costs 128 credits at 480p, 280 at 720p and 640 at 1080p. The creator shows the current price before submission.

How long does processing take and what if it fails?

Processing time varies. Follow the job in Studio; do not submit the same video again while it is processing or under review. Credits are returned after a confirmed failure according to the generation rules.

Is the original audio included?

The uploaded source and public preview retain the original audio. The generation requests source-audio preservation; you must have permission to use any music when sharing.
