Frequently asked questions

How do I create a Birthday Glow-Up video?

Upload the six references, choose 480p, 720p or 1080p and generate. Genjutsu transfers the original studio motion and birthday transformation to your references.

Which six photos do I upload?

Upload one model photo, three separate outfit photos in appearance order, then the cake before and after. Each slot takes one image.

Which outfit is shown first?

Outfit 1 is the opening standing look. Outfit 2 follows during the middle transition; Outfit 3 is the final birthday look. Keep each photo in its labeled slot.

How do the before and after cake photos work?

The before cake appears when the cake first enters the scene. The after cake replaces it at the original candle or number change. Use clear photos showing the decorations and any desired numbers; exact lettering is not guaranteed.

What makes a good model and outfit reference?

Use a clear photo of one consenting adult and separate, well-lit outfit photos. Visible garment shape and fabric details help; blur, collages and obscured faces can reduce fidelity.

How much does it cost and what is the output?

The clip is approximately 15 seconds in vertical 9:16. Current prices are 240 credits at 480p, 525 at 720p and 1,200 at 1080p. Check the Generate button for the current cost.

Will the result match the example exactly?

No. The preview demonstrates the source performance; your photos change the person, wardrobe and cakes. Identity, fabric detail and candle text can vary.

Can I leave while the video is processing?

Yes. Check Studio for the result. Processing time depends on the provider and queue; no fixed completion time is promised.

What if the job fails or needs review?

Check Studio and Credit activity for status and any returned credits. If the result is being checked, do not submit the same video again yet; contact support@retwist.ai with the job ID.

May I publish the result with its audio?

Use photos you own or have permission to use and obtain consent from the person. Source audio does not grant music rights; confirm those rights before publishing.
