MiniMax H3 Video Editor

Describe localized changes to a source video while locking every unaffected property. Stay prompt-only and never submit a generation job.

Confirm this workflow

Use this skill when at least one existing video is the source to modify. Route execution through reference-conditioned video generation; label the source as Video 1 unless the user's existing ordering differs. Additional images, videos, or audio may supply replacement identity, design, environment, motion, or voice.

Recommend 5–15 seconds, 768P for iteration or 2K for a final pass when supported, and a fixed or adaptive aspect ratio. Preserve the source duration or aspect when that is important to the edit, and let the executor validate the installed workflow.

Write change-and-preserve pairs

Create a short edit ledger before the prompt. For each operation, pair:

• Change: exact target, location or time, operation, and replacement source.
• Preserve: surrounding subjects, action, timing, framing, lighting, shadows, reflections, geometry, audio, text, or effects that must remain stable.

Examples of precise operations include replace, remove, add, relight, recolor, rewrite, retime, and overlay. Avoid broad restyling language unless broad restyling is the requested edit.
