Toono
ByteDance long-form multimodal video model

Carry one visual story through a longer, reference-rich sequence

Direct 5–30 second videos with text, start and end frames, or a large multimodal reference set. Use up to 30 images, 10 videos, and 10 audio files, choose 480p or 720p, and generate optional native sound.

Longer output raises the review burden. Draft one clear story beat first, then inspect identity, transitions, text, products, and audio across the entire clip.

These clips test whether the model can hold a subject, action arc, camera plan, and sound direction together across different commercial briefs.

Reference story baseline

A concise motion brief provides a common baseline for continuity, framing, and sound.

Skincare ritual

Hands, reflective packaging, and a quiet camera test fine-detail consistency and pacing.

Running shoe story

A multi-beat product scene tests shape stability, energetic motion, and a purposeful finish.

Desktop speaker launch

Lighting changes and sound cues test product geometry, atmosphere, and synchronized audio.

The Toono test clips use economical 480p, 5-second settings with native audio. The workspace supports 5–30 seconds and 480p or 720p for longer production tests.

Practical workflow

Plan the story before filling the reference limits

The larger input canvas is useful when each asset controls a known subject, location, motion, sound, or transition. More files are not automatically more control.

  1. 01

    Write the beat sheet

    Define the opening state, two or three important beats, camera language, sound intent, and final state before choosing assets.

  2. 02

    Assign reference roles

    Use a start/end frame path or a multimodal set with up to 30 images, 10 videos, and 10 audios. Remove any asset without a clear job.

  3. 03

    Test short, then extend

    Prove identity, motion, and edit logic in a 5-second 480p run before committing credits to 720p or a 30-second sequence.
