What will change

Your portrait targets only the central performer wearing sunglasses and a pink shirt. The people around him should stay as they are. AI can miss an identity or change background details, so review the full result.

Small timing differences are aligned to the source length. Face quality and lip sync need your review.

AI CASE EXAMPLE

See the lead as a blue character.

This example result shows an AI character treatment on the central performer while the surrounding scene remains recognizable. Play the case video to see the result in motion.

This supplied case is a 6-second, 360 × 640 silent example. It is separate from the studio’s 5, 12 and 23-second generation options, which use the original clip and restore its audio. Results can vary.

THE ORIGINAL SOURCE

Watch the 23-second scene.

The lead performer appears in the center wearing sunglasses and a pink shirt. The studio uses this video from 0:00; shorter options take its first 5 or 12 seconds.

This is the original footage, not an AI result. The model is instructed to change only the lead, but identity and background details can vary. Review the generated video before using it.

BEFORE YOU CREATE

Bulin 47 AI questions.

What to expect from this single-photo scene workflow.

Which person does my photo replace?

Your photo targets only the central performer wearing sunglasses and a pink shirt. The people behind him and the people holding phones in front are meant to stay as they appear in the source. AI can make mistakes, so inspect the finished clip.

How many photos do I need?

One clear portrait. Upload a JPEG, PNG or WebP image up to 10 MB. You need permission to use that person’s likeness; a parent or guardian must authorize the use of a minor’s photo.

Which part of the source is used?

Choose the first 5, 12 or 23 seconds of the supplied clip. Every cut starts at 0:00, and the studio previews the exact cut you select.

Will the original sound be in my result?

After generation, the original source audio is restored to the output. Check the finished video for timing and lip sync before sharing.

How many credits will it use?

The exact quote depends on the length and resolution you choose. The studio displays it before you confirm generation. See credit pricing.
