What you can build with this model

Real-world workflows and production use cases you can build and ship with this model.

Sound in the same render

Dialogue, ambience and effects come with every reAPI Video 1 clip, generated from the same prompt as the picture. No voiceover pass, no lip-sync step: describe the room tone and the effects, and say no music when you do not want a bed.

Generate a clip

Name the camera, get the look

reAPI Video 1 responds to a real camera body, lens and aperture far more than to words like cinematic. Write the shot the way a crew would brief it and keep the camera still: short, contained shots with one subject are where it is strongest.

Keep your product in the shot

Give reAPI Video 1 photos, clips or audio in reference mode and the colour, form and markings of what you supplied carry into a new scene. Address each one in the prompt as Picture 1 or Video 1. Write each label in angle brackets.

Why reAPI for reAPI Video 1

Picture and sound together

Every reAPI Video 1 clip carries its own stereo track of dialogue, ambience and effects, so a talking scene or a product shot is finished in one request.

Does what you asked

reAPI Video 1 follows a brief literally and keeps objects at their size and place. No dialogue in the prompt means no dialogue in the clip.

Repeatable shots

Fix the seed and reAPI Video 1 returns the same clip for the same prompt, so you can change one detail at a time instead of starting over.
