Musebox Feature Guide: Extend, Animate, Sound and Characters

Image-to-video

Input: an uploaded photo. Controls can include template, style or motion, custom and negative prompts, quality, frame rate, duration and model-specific add-ons. Output: a short video in Collection. This mode preserves the starting composition but cannot invent missing off-frame detail reliably.

Text-to-video

Input: a written scene. Controls depend on the model and may include style, movement, duration and quality. Output: a new scene from the prompt. Unlike image-to-video, no uploaded composition anchors the first frame.

Picture generation and Animate

Picture templates create a still from a prompt or image workflow. Animate adds motion to that result. The official guide lists Animate at 15 extra credits and describes motion and depth; the exact movement depends on the template and source.

Extend Video

Input: a generated video selected from Extend or Collection. The app uses the end state as the next starting point and can apply extension more than once. A public fixed cost was not found, so record the estimate for each step.

Sound and Remix

Input: a generated clip. Musebox exposes an option described as adding realistic sounds and a Remix sound workspace. Output: a video with generated audio or soundtrack treatment. Public pages do not publish a universal audio duration or format.

Character and private-model tools

The app has character pages and a Train workflow. Input is reference material used for a reusable identity. The output is a selectable character or model for compatible workflows. Reference count, training cost and model compatibility must be checked in the live configuration.

Advanced prompts and Usage Tips

Custom Prompt adds desired content, Negative Prompt names content or artifacts to avoid, and Usage Tips gives template-specific input guidance. These are explicit controls. Advice such as simple backgrounds or changing one variable remains an editorial method, not a named tool.

Which feature to choose

Use image-to-video when composition matters, text-to-video for a scene from words, Animate for motion from a still, Extend after approving a base clip, sound after the picture edit is stable, and a character or private model when identity must repeat. Confirm cost and compatibility before a multi-step sequence.
